2 Selection table current relay, mains monitoring relay, current-limiting relay and mains disconnection relay The bodyguards ELTAKO mains disconnection relays switch off a monitored 230V conductor after connected loads are switched off manually. This prevents interfering electromagnetic alternating fi elds. A DC voltage with an extremely low residual ripple is used for monitoring purposes. No measurable alternating fi eld is generated but it is guaranteed that room lighting is detected when switched on. The monitored conductor is then switched on again. Electronically controlled loads or supplied loads, require a high degree of monitoring effort. Here, the self-learning mains disconnection relays are ideal for such applications.

With an internal toroidal-core current transformer the single phase AC current flowing through a consumer V1 of 0.1A up to max. 32A is compared to the setpoint. When the latter is exceeded a special relay with high capacity switches off a consumer V2 connected to 2 within 0.5 seconds or switches on a consumer V3 connected to 3. Adjustment accuracy ±5%. From 25A the relay always switches on. Zero passage switching to protect contacts and consumers. State-of-the-art hybrid technology combines advantages of nonwearing electronic control with high capacity of special relays. The basis of current A will be set with the lower rotary switch A. The following basic values can be selected: 0.1A, 0.3A, 0.6A, 0.9A,1.5A,1.9A, 3.0A and 3.2A. The multiplier xa will be set with the middle rotary switch xa and offers values between 1and 10.

The current-limiting relay is connected on the load side of the protected relay contact. Permanent load max W, max. switching frequency 600/ h. Explanation of capacitive load specification: The specified max. capacitive load directly at the mains is the deciding factor determining shunt-compensated fluorescent lamps or conventional ballast, for example.

6 Self-learning mains disconnection relay FR12 FR12-230V V G4 Rotary switches Standard setting ex factory. monitored circuit 1 NO contact not potential free 16A/250V AC. Incandescent lamp load 2300W. Standby loss 0.8 watt only. Modular device for DIN EN rail mounting. 1 module =18mm wide and 58mm deep. 230 V supply voltage and switching voltage. State-of-the-art hybrid technology combines advantages of nonwearing electronic control with high capacity of special relays. The FR12-230V mains disconnection relay disconnects the power supply once all series connected loads are turned off, thus preventing any electromagnetic interference fields from occurring. Small loads up to 200mA, are acceptable and, once major loads are disconnected, they do not prevent field disconnection. There is no need to manually set the limit; it is learned by the FR12. Loads drawing more than 200mA are consistently defined as loads which should cause the line power to be connected. As long as no major load is turned on, one pole of the monitored circuit remains isolated from the mains. Neutral and earth are connected continuously to avoid acting as an aerial. A DC voltage with an extremely low residual ripple is applied for monitoring. Therefore, it is prohibited to bridge the relay contact, which would ultimately cause device failure. When a load is turned on, the mains disconnection switch connects the monitored phase after approx. 1 sec and the LED lights red. Function of the lower rotary switch In the function ON/ position, the relay contact is continuously closed and field disconnection deactivated. Turn the switch to the position A = automatic with 'self-learn mode', the actual current value is saved as a switch-off value. When this value is reached, the FR12 breaks the electrical circuit regardless whether small consumers such as electronic dimmers are connected. Therefore, the lighting must always be OFF for learning by means of the rotary switch. When the switch is in the A position the FR12 adapts to changes in connected consumers. The FR12 performs a new learn-in routine after phase is activated and when the power supply is restored after a power failure. If a new small load is switched on for more than 24 hours, the total current drawn by the monitored circuit is less than 200mA, the FR12 is set to A mode and in the meantime the light has been switched on and off, the new load is learned in and the conductor is switched off. When the rotary switch is set briefly from A to, learn-in takes place immediately after connecting a new load. If the function self-learn is not required, set the rotary switch to A automatic OFF. Function of the upper rotary switch The monitoring voltage can be adjusted in the range from 5V DC to 230V DC. Due to its low residual ripple, it generates no measurable alternating field even at 230V DC. The higher the adjustment, the greater the number of capacitive loads detectable without switching on a base load. It can therefore be reduced until the loads are barely detectable. In many applications, even the lowest monitoring voltages are detectable. Technical data page G6. Housing for operating instructions GBA12 page Z2.

7 Self-learning mains disconnection relay FR61, accessory base load FR V 1 NO contact not potential free 10A/250V AC. Standby loss 0.8 watt only. Side view monitored circuit Built-in device for installation and surface mounting 45mm long, 55mm wide, 26mm deep. 230 V supply voltage and switching voltage. State-of-the-art hybrid technology combines advantages of nonwearing electronic control with high capacity of special relays. The FR61-230V mains disconnection relay disconnects the power supply once all series connected loads are turned off, thus preventing any electromagnetic interference fields from occurring. Small loads up to 20mA are acceptable and, once major loads are disconnected, they do not prevent field disconnection. There is no need to manually set the limit; it is learned by the FR61. Loads drawing more than 200mA are consistently defined as loads which should cause the line power to be connected. As long as no major load is turned on, one pole of the monitored circuit remains isolated from the mains. Neutral and earth are connected continuously to avoid acting as an aerial. A DC voltage of 230V DC with an extremely low residual ripple is applied for monitoring. Therefore, it is prohibited to bridge the relay contact, which would ultimately cause device failure. When a load is turned on, the mains disconnection relay connects the phase. If the phase is switched on for the first time and after a power failure the FR61 automatically learns in again: At first an inrush current of 30mA is specified. If a new small load is switched on for more than 24 hours, the total current drawn by the monitored circuit is less than 200mA, and in the meantime the light has been switched on and off, the new load is learned in and the conductor is switched off. This learn-in mode can be realised immediately after connection of the new load by briefly switching off the MCB. G5 Technical data page G6. FR61-230V 1 NO 10 A EAN GLE Accessory base load A base load is used if loads cannot be detected due to their capacitance but are meant to switchon the line voltage. Base loads must consistently start or operate in parallel with the related loadand be turned off with the latter. Higher stand by loads may affect or jam the detection of a base load. Typical applications: Fluorescent lamps, dimmer circuits and electronic transformers. GLE base load element PTC in a small coupler with connecting leads; can be used directly in a load, a switch box or a junction box. It is not capable of keeping the mains disconnection relay in the connected state without an additional load connected. GLE 1x base load EAN Recommended retail prices excluding VAT.
