The Bussmann 187 circuit breakers feature a single lever for switching and manual reset. They are ignition protected and weatherproof (IP 66 rating). Typically used in DC power systems in marine applications (as a main or branch circuit breaker), truck and bus systems, RV systems, add-on protection for accessories, lift gates, etc.

Manual reset circuit breakers will open the circuit on overload and will remain open until the user presses the yellow switch lever. This circuit breaker can also be manually switched off using the yellow lever.

Typically used in DC power systems in marine applications (as a main or branch circuit breaker), truck and bus systems, RV systems, add-on protection for accessories, lift gates, etc.
