FAZ Series - Supplementary Circuit Breakers (UL-1077) - General Information
 
Supplementary Circuit Breaker - General Information
 
Moeller’s FAZ line of miniature circuit breakers includes a broad range of devices defined as “supplementary protectors.” These breakers comply with UL 1077 and CSA 22.2 No. 235 regulations defining supplementary over-current protection. In these applications, branch circuit protection is not required, or is provided by a separate device like afuse or molded case circuit breaker. FAZ 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.
Moeller - Faz Series Supplementary Circuit Breakers  
Extensive product range
Moeller Supplementary Protectors are available in one, two and three pole configurations and up to 17 different current ratings from 0.5A to 63A. One pole plus neutral, and three-pole plus neutral devices are also available. Six different trip characteristics including B, C, D, K, S and Z curves give you the ability to configure the exact protection scheme you require. Devices can be used in applications up to 480V AC and 48V DC with short circuit ratings up to 10kA.
 
Straightforward installation
All breakers mount on a standard 35mm 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.
 
Standard features enhance safety
As with most products from Moeller, FAZ 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 FAZ breakers also incorporate a “trip-free” mechanism. This prevents the trip function from being defeated by holding the operator in the ON position.
 
Worldwide acceptance Six Tripping Curves
FAZ Supplementary Protectors are UL Recognized for use in the United States in accordance with NFPA 70 (NEC). The devices comply with UL 1077 and CSA 22.2 No.235, meeting the requirements for supplementary protectors. These devices also comply with IEC 60898 and are CE marked.

Six tripping curves to choose
Moeller FAZ Supplementary Protectors are available with six different tripping characteristics, including Type B, C, D, K, S and Z. 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 (3 to 5 X continuous rating of the device (In).
Even though not required by NEC or CEC for Supplementary Protectors, Moeller’s FAZ 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.
