More about supplementary protectors
Supplementary protectors are compact overcurrent protection devices related to the broader circuit breakers family but evaluated under UL 1077 rather than UL 489 standards. Unlike standard branch circuit breakers, supplementary protectors are used in applications where code does not require a branch circuit breaker. They are commonly found inside control panels, machinery, and equipment protecting individual components and internal wiring.
