Bussmann Automotive Products, a division of Cooper Industries, has introduced the Series 187 Marine Rated Circuit Breaker (MRCB).

The Series 187 MRCB is a Type 3 manual reset style circuit breaker with a switching function. A yellow lever on the cover identifies the on-off switching function, and is easily accessible. It allows the MRCB to be used as the main circuit breaker in DC electrical systems. Available in ratings from 25 to 150 amps, the MRCB comes in panel- and surface-mount models.

The MRCB is molded of UL 94VO materials and is weatherproof and CE-registered. Other features include:

• Ignition protected per ABYC E-11 requirements (Tested per SAE J1171).

• Main breaker protection interrupt rating (5 kA per AYBC E-11 @ 12 volts DC). Overall interrupt ratings: 5 kA @ 12 volts, 3 kA @ 24 volts, 2 kA @ 36 volts, and 1 kA @ 48 volts.

• 5/16-18 electrical termination studs — corrosion-resistant materials, optional stainless nuts, and lock washers.

• Mounting hole clearance is designed to allow use of 5 mm or 10-32 screws.
