EATON 187 Marine Rated Circuit Breakers

EATON Series 187 Marine Rated Circuit Breakers (MRCB) feature a manual reset with on-off switch capability and are single-pole thermal type. The MRCB circuit breakers are designed with a black UL-rated 94V0 thermoset plastic body, and the cover and lever are UL-rated 94V0 thermoplastic material. These circuit breakers operate at a temperature range from -40°C to 85°C and a current rating from 25A to 200A . The 187 marine-rated circuit breakers are used in DC power systems in marine applications (as a main or branch circuit breaker), truck and bus systems, lift gates, and RV systems.
