The Kussmaul Waterproof Circuit Breakers provide dependable high-amperage circuit protection and manual switching for fire apparatus, ambulances, rescue vehicles, command vehicles, marine applications, and other specialty vehicle electrical systems. Combining a circuit breaker and disconnect switch in one compact, surface-mounted unit, these breakers help protect electrical circuits from overloads while allowing operators and technicians to manually de-energize circuits for maintenance and service.

Featuring a triple-delay trip curve, the circuit breakers accommodate temporary high-current surges commonly associated with motor starting while providing reliable overload protection. A push-to-disconnect button allows the circuit to be manually de-energized, while the integrated latch arm resets the breaker after an overload condition. For added safety, the breaker cannot be held in the ON position when a short circuit remains present. The waterproof construction provides dependable performance in demanding environments where electrical components may be exposed to moisture and harsh operating conditions.
