Buyers Products Company CB50PB 50 A Circuit Breaker

SKU CH-XA02-0E0P8

A 50 A manual-reset circuit breaker for auxiliary circuits on dump trucks, snow plows and trucks, rated 42 V DC with push-to-trip actuation

  • 50 A protection for auxiliary circuits
  • 42 V DC rating suits truck and plow systems
  • Manual push-to-trip reset restores power instantly
  • Stud terminals give secure high-current connections
  • Compact 1 7/8 in plastic housing fits tight panels

High-amperage circuit protection

The Buyers Products CB50PB is a manual-reset, hi-amp circuit breaker rated for 50 A at 42 V DC with a 50 A interrupt rating. It mounts on a surface using bolt-on studs and uses a push-to-trip actuator for manual testing and isolation. The plastic housing measures 2 7/8 in deep by 1 7/8 in wide.

Suited to auxiliary truck circuits

This breaker protects auxiliary and accessory circuits on dump trucks, snow plows and similar work trucks where a resettable device is preferred over a fuse. It is not intended for branch circuits requiring automatic reset or for systems operating above the 42 V DC rating. Installers needing a different current rating or an automatic reset function should select an alternative device.

The 50 A current rating decides fit

Match the breaker’s 50 A rating to the maximum continuous load of the circuit it protects; the conductor ampacity and the load requirement determine whether this specific unit is correct. The 42 V DC voltage rating and 50 A interrupt rating must also align with the system voltage and prospective short-circuit current.
