What Is a Circuit Breaker Enclosure?
Circuit breaker enclosures are cabinets designed to protect circuit breakers. Suitable enclosures are necessary for circuit breakers used outdoors to ensure they meet outdoor ratings and to protect against dust and corrosion.
Basic indoor enclosures protect against dirt and dust, while outdoor variants offer additional protection against rain, sleet, and snow. Some enclosures also safeguard against falling dirt, airborne dust, and direct water from hoses.
