Description
The Niglon 4CBR-400 is a 400A four-pole CBR — a moulded-case circuit breaker (MCCB) combined with an integral residual current device. It delivers overload, short-circuit and earth-fault protection for main and sub-main three-phase distribution in one device.
Adjustable thermal release (0.8–1.0 In), fixed magnetic protection and an adjustable earth-fault threshold (100 / 300 / 500mA) with adjustable time delay (50 / 500 / 800ms) allow the protection to be tuned to the installation. Rated 400/415V with a high short-circuit breaking capacity.
