The VALUE COLLECTION BDKP4665 is a miniature circuit breaker (MCB) rated at 25 amps and 12 volts DC, sold in a pack of two. It uses a plug-in mounting configuration, allowing fast installation into compatible breaker panels and distribution blocks without additional hardware. At 0.44 inches wide and 1.0 inch tall, this compact breaker fits space-constrained enclosures common in automotive, marine, and low-voltage DC applications. Electricians and automotive technicians install this type of breaker to provide overcurrent protection for wiring circuits in 12V systems. The unit meets SAE J553C standards, confirming suitability for vehicular electrical environments.
This breaker is suited for 12-volt DC applications including automotive wiring, RV and marine electrical panels, low-voltage control panels, and similar installations where compact overcurrent protection is required. The plug-in mount makes it compatible with modular breaker blocks commonly found in these systems. Each order includes two breakers, making it practical for multi-circuit service work or stocking a service van with spares.
Designed for use in 12-volt DC plug-in breaker panels typical of automotive, marine, and RV electrical distribution applications conforming to SAE J553C requirements.
Installation should be performed by a qualified electrician or automotive technician familiar with low-voltage DC systems. Disconnect and isolate the power source completely before removing or inserting the breaker into the panel. Confirm that the panel or distribution block accepts plug-in style miniature circuit breakers before installation. Verify that the circuit load does not exceed the 25-amp rating of the breaker after installation.
