Miniature Circuit Breakers

Miniature Circuit Breakers
Miniature Circuit Breakers (MCBs) are UL489 Listed and can be used for branch protection as the primary overcurrent device. Supplementary Protectors are UL 1077 Recognized and designed for supplemental protection within a control panel, appliance, or other electrical equipment. MCBs and supplementary protectors have fixed trip settings and do not require replacement upon being tripped, and instead they can be reset manually and reused.
