4 UL 0 DIN Rail Supplementary Protectors Product Overview UL 0 DIN Rail Supplementary Protectors PRODUCT OVERVIEW Product Overview Standard Features WMZS breaker terminals provide finger and back-of-hand protection to guard against accidental contact with live parts. A color-coded red/green indicator provides immediate visual indication of device status (green for OFF, red for ON) and isolation function. All WMZS breakers also incorporate a trip-free mechanism. This prevents the trip function from being defeated by holding the operator in the ON position. Eaton s WMZS line of miniature circuit breakers includes a broad range of devices defined as supplementary protectors. These breakers comply with ULT 0 and CSAT. No. regulations defining supplementary overcurrent protection. In these applications, branch circuit protection is not required, or is provided by a separate device like a fuse or molded case circuit breaker. WMZS Supplementary Protectors are typically used for control circuits, lighting, business equipment, appliances and a range of other applications where closer protection is desired than that offered by a branch circuit protection device. Worldwide Acceptance WMZS Supplementary Protectors are UL Recognized for use in the United States in accordance with NFPAT 0 (NECT). The devices comply with UL 0 and CSA. No., meeting the requirements for supplementary protectors. These devices also comply with IEC 09- and are CE marked. These devices are RoHS compliant. Extensive Product Range Eaton s Supplementary Protectors are available in -, - and -pole configurations and 0 different current ratings from 0.A to A. Three different trip characteristics, including B, C and D curves, give you the ability to configure the exact protection scheme you require. Devices can be used in applications up to 80 Vac and 8 Vdc with short-circuit ratings up to 0 ka. Ease of Installation All breakers mount on a standard mm DIN rail. Each device has box terminals that accept multiple conductors. Bus connectors and feeder terminals facilitate mounting and wiring of multiple miniature circuit breaker arrays in control panel assemblies. Power to the circuit breakers can also be fed from the line or load side. eaton corporation UL 0 DIN Rail Supplementary Protectors

5 UL 0 DIN Rail Supplementary Protectors PRODUCT OVERVIEW Discover These Advanced Features Three Tripping Curves to Choose Breakers install on standard DIN rail Captive posidrive terminal screws with finger and back-of-hand protection (IP0) Eaton WMZS Supplementary Protectors are available with three different tripping characteristics, including Type B, C and D. Definitions for each trip curve are contained on the ordering pages and can be used to determine the optimal characteristic for your application. For example, low level short-circuit faults in control wiring, such as PLCs, are best protected by devices with Type B trip characteristics ( to X continuous rating of the device (I n ). Product Overview Available in -, - and -pole models Color-coded indicator provides breaker status for easy troubleshooting Trip-free design; breaker cannot be defeated by holding the handle in the ON position Breaker information printed on the front of the device for quick identification Even though not required by NEC or CEC for Supplementary Protectors, Eaton s WMZS devices are current limiting, which means they interrupt fault currents within one half cycle. Current limiting devices offer superior protection by reducing peak let-through current and energy Time-current characteristic acc. to UL 0 a conventional non-tripping current I nt =.
