DNA CBM200Y 200A Manual Reset Circuit Breaker 12-48V DC IP67 Waterproof
A 200A manual reset circuit breaker from DNA, the CBM200Y 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 electrical system protection applications requiring higher current capacity.
Product Overview
The DNA CBM200Y is a 200A manual reset circuit breaker for use in 12V, 24V, and 48V DC electrical systems including vehicles, caravans, marine installations, and dual battery setups where higher current draw requires a 200A protection rating. Sharing the same IP67 waterproof and ignition-protected specification as the CBM150Y, the CBM200Y suits exposed installation positions in engine bays, under-vehicle locations, and marine environments. The 6mm studs accept 8-6 or 22-6 crimp lugs. Manual reset operation allows the breaker to be reset by hand after a trip event without replacement.
Features & Benefits
200A Rating - 12-48V DC Operation: Rated at 200A across 12V, 24V, and 48V DC, providing higher current capacity protection for demanding electrical installations including large amplifier systems, winches, high-draw dual battery setups, and commercial vehicle sub-circuits.
Manual Reset - Reusable Protection: Manual reset allows the breaker to be reset by hand after a trip event, providing reusable circuit protection 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.

Frequently Asked Questions
What is the difference between the CBM200Y and the CBM150Y?
Both are DNA manual reset circuit breakers with the same IP67, ignition-protected, 12-48V DC, and 6mm stud specification. The CBM200Y is rated at 200A for higher current draw applications. The CBM150Y is rated at 150A for standard installations. Choose based on the maximum continuous current draw of the circuit being protected.
Is the CBM200Y suitable for marine installation?
Yes. The IP67 waterproof rating and ignition-protected design make the CBM200Y suitable for marine installation in exposed positions.
Does the CBM200Y 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 CBM200Y studs?
The 6mm studs are compatible with 8-6 or 22-6 crimp lugs.
