Specifically they increase for temperatures below 25 C (5SJ41), 30 C (5SP, 5SX, 5SY) and decrease for temperatures above 25 C (5SJ41), 30 C (5SP, 5SX, 5SY). For DC voltages the maximum current values of the instantaneous tripping operation increase by a factor of 1.2. If more that one electrical circuit is loaded in a series of miniature circuit breakers or supplementary protectors, the resulting increase in ambient temperature affects the characteristic curve. In this case an additional correction factor found in the following table must be used.

General Data 5SX, 5SY and 5SP Supplementary protector Application Design Features Siemens' UL 1077 Supplementary Protectors are designed to provide additional protection along with a branch circuit protection device. Since our Supplementary protectors are made to trip faster than a standard UL 489 Circuit Breaker they are able to provide additional protection for more sensitive devices inside the panel. Supplementary protectors can be used in a number of industrial applications such as to provide selectivity for multiple motor control circuits on the secondary side of a control transformer or power supply by allowing the user to quickly find the problem circuit should a fault occur with out having to shut down all of the other control circuits. Supplementary protectors may also be used as a local disconnecting means inside the panel when a branch circuit protection device is already present. Always remember to follow the National Electric code when wiring your panel for applications within the United States. Supplementary protectors are equipped with a delayed overload/time-dependent thermal release (thermal bimetal) for low overcurrents and with an instantaneous electromagnetic release for high overload and short-circuit currents. The special contact materials used guarantee a long service life and offer a high degree of protection against contact welding. Mode of operation Thanks to the extremely fast contact separation in cases of failures and the rapid quenching of the arc consequently generated in the arcing chamber, supplementary protectors assure a safe and current-limiting off-switching. The permissible limit-i 2 t-values of the energy limitation class 3 specified in EN 60 898 are generally undercut. This guarantees an excellent selectivity towards upstream overcurrent protection devices. High rated breaking capacity of up to 10,000 A acc. to EN 60 898 / up to 15 ka acc. to EN 60 947-2 Excellent current limiting and selectivity characteristics Tripping characteristic A, B, C and D Terminals offer protection against contact with fingers or the back of the hand acc. to the German accident prevention regulations VBG 4/ BGV A2 Combined terminals enable a simultaneous connection of busbars and feeder cables Uniform components that can be quickly mounted individually, thanks to their snap-on technique The handle locking device effectively prevents any unauthorized operation of the handle Features of 5SY Rapid connection of the feeder cable in front of the busbar Identical terminals at both sides for an optional infeed from the top or the bottom No tool required for mounting or dismounting Supports a fast and comfortable removal from the assembly Separate switch position indication Features of 5SP4 Disconnection characteristics acc. to EN 60947-3 (DIN VDE 0660 Part 107) Main switch characteristics acc. to EN 60 204-1 Can be screwed onto bases Separate switch position indication.
