0UCB20.XP

CBK UNIVERSAL CIRCUIT BREAKER 20A 1PC CRD

This is a 20-amp, 12-volt DC universal ATO-type circuit breaker that automatically resets when power is removed. It plugs directly into standard ATO/ATC fuse blocks, protecting wiring harnesses in trucks, trailers, and other 12V electrical systems. The Type II modified reset design stays open while power is present and resets only after the ignition is turned off, making it ideal for power windows, seats, sunroof circuits, or anywhere a fuse replacement is inconvenient.

Verified fitment

  • Any 12V DC system using ATO/ATC fuse blocks
  • Trailer wiring harness protection
  • Truck power accessory circuits (windows, seats, sunroofs)

Part number appears to be a typo; the correct manufacturer SKU is 0UCB020.XP. This breaker is a universal replacement for any ATO-style fuse position and conforms to SAE J553C.
