Bussmann Automotive Products, a division of Cooper Industries, offers a new standard class of thermal circuit breakers. The new product family, called the Mid-Range 250 Series, was developed primarily for the medium-duty chassis industry and for specialized vehicles.
Mid-Range 250 breakers come in three versions: automatic reset, manual reset, and manual reset with push-to-trip. The extra push-to-trip feature allows the opening of a circuit path without disconnecting it from the power source.
All versions are provided in amperages from 10 through 50, and are formed with a rounded profile body and cover boss that allows a three-hole panel cutout mounting. Available with 10-32 stud terminals and nuts, the Mid-Range Series is produced with corrosion-resistant material; stainless steel lock nuts are optional. Additional features include:
Ignition protection (ABYC E-9/SAE J1171)
Branch protection interrupt rating (2.5k A per ABYC E-9)
Cover assembly with overmold gasket allows for integrated breaker-to-panel splash proofing
Same standard mounting centers used by other manufacturers. (1.574"/40 mm)
Two formats for mounting: eyelets for 10-32 clearance and threaded inserts for 8-32 clearance
