Moeller Electric'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 a fuse 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.

The FAZ 'C' curve miniature circuit-breaker covers the rating range from 0.5 to 50 A  with a 6-10 times trip for inductive loads, such as motor loads. (Also available in five different tripping characteristics providing the ideal solution for all applications from semiconductor protection to cable production, up to the protection of control transformers.)
