A 50A manual reset circuit breaker from DNA, the CBM050Y operates across 12-48V DC with IP67 waterproof protection, ignition-safe design (no spark or heat during use), and 6mm studs for termination with 8-6 or 22-6 lugs, suited to automotive, marine, caravan, and 4WD sub-circuit and accessory protection at 50A.
The DNA CBM050Y is a 50A manual reset circuit breaker for use in 12V, 24V, and 48V DC electrical systems. Sharing the same IP67 waterproof and ignition-protected specification as the CBM100Y, CBM150Y, and CBM200Y, the CBM050Y is suited to lower-current sub-circuit and accessory protection applications including individual amplifier feeds, accessory circuits, lighting sub-circuits, and auxiliary power points where a 50A rating is appropriate. IP67 rating enables installation in engine bays, exposed exterior positions, and marine environments. The 6mm studs accept 8-6 or 22-6 crimp lugs. Manual reset allows the breaker to be reset by hand after a trip event without replacement.
50A Rating - 12-48V DC Operation: Rated at 50A across 12V, 24V, and 48V DC for lower-current sub-circuit and accessory protection in passenger vehicles, commercial vehicles, caravans, 4WDs, and marine installations.
Manual Reset - Reusable Protection: Manual reset allows the breaker to be reset by hand after a trip event without requiring replacement.
IP67 Waterproof - Engine Bay and Marine Ready: IP67 rated for full dust protection and temporary water immersion for installation in engine bays, exposed exterior locations, and marine environments.
Ignition Protected - No Spark or Heat During Use: No sparking or heat generation during operation for safe installation near fuel systems and in confined environments.
6mm Studs - Compatible with 8-6 and 22-6 Lugs: The 6mm stud terminals accept 8-6 or 22-6 crimp lugs for a clean, secure, and vibration-resistant wiring termination.

The CBM050Y is compatible with 12V, 24V, and 48V DC electrical systems. The 6mm studs accept 8-6 or 22-6 crimp lugs. For higher current applications refer to the DNA CBM100Y (100A), CBM150Y (150A), or CBM200Y (200A). Confirm the required amperage rating and system voltage against your specific electrical installation before purchase.
How does the CBM050Y compare to the other DNA CBM circuit breakers?
All DNA CBM circuit breakers share the same IP67, ignition-protected, 12-48V DC, and 6mm stud specification. The CBM050Y is the lowest-rated at 50A for lighter sub-circuit applications. The CBM100Y is rated at 100A, the CBM150Y at 150A, and the CBM200Y at 200A for progressively higher current draw applications. Choose based on the maximum continuous current draw of the circuit being protected.
Is the CBM050Y suitable for marine installation?
Yes. The IP67 waterproof rating and ignition-protected design make the CBM050Y suitable for marine installation in exposed positions.
Does the CBM050Y need to be replaced after a trip event?
No. The manual reset design allows the breaker to be reset by hand after a trip event and reused.
What lug size is compatible with the CBM050Y studs?
The 6mm studs are compatible with 8-6 or 22-6 crimp lugs.
