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.R Series supplementary protectors are available in one, two, and three-pole configurations and up to 20 different current ratings from 0.5A to 60A and can safely be used in applications up to 480Y/277 Vac with a 10 kA short circuit withstand Rating.
Three different trip characteristics, including B, C and D curves, give you the ability to configure the exact protection scheme you require.
B-Trip Protectors
Include business equipment, wiring protection, lighting, appliances, control circuits and some electronic applications. Relatively long thermal trip delay but low magnetic trip point.
C-Trip Protectors
Include lighting, wiring protection, appliances, business equipment, and control circuit applications. Relatively long thermal trip delay and medium magnetic trip point.
D-Trip Protectors
Include control transformers, power supplies and reactive loads. Relatively long thermal trip delay and very high magnetic trip point.
