Encapsulated NEC Molded Case Circuit Breakers

Eaton's Crouse-Hinds series GHG 627 encapsulated molded case main circuit breakers deliver maximum safety for your facility by providing overcurrent and short circuit protection for 50A to 225A low voltage power, lighting and heat tracing applications in Division 2 & Zone 1/2 hazardous areas.

Our encapsulated main circuit breakers are permanently welded to prevent tampering and promote safety.  Engineered heat dissipation ribs and an air gap design prevents hot spots by promoting air flow.  This helps achieve a wide operating temperature range of -20°C to +40°C.

GHG 623 encapsulated molded case circuit breakers provide safe and efficient power distribution in refineries, chemical and petrochemical plants, water treatment facilities, food processing, and industrial processing facilities.
