Eatons WMZS line of miniature circuit breakers includes a broad range of devices defined as supplementary protectors. These breakers comply with ULT 1077 and CSAT 22.2 No. 235 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.
