Description
While UL489 branch circuit breakers protect feeder or branch circuits, R Series UL1077 supplementary protectors are made to trip faster than a standard UL489 circuit breaker, therefore providing additional protection for specific devices. Supplementary protectors provide critical protection in applications where branch circuit protection is not required, or is already provided by a separate device.
