DNA CBM150Y 150A Manual Reset Circuit Breaker 12-48V DC IP67 Waterproof
A 150A manual reset circuit breaker from DNA, the CBM150Y 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.
Product Overview
The DNA CBM150Y is a 150A manual reset circuit breaker designed for use in 12V, 24V, and 48V DC electrical systems including vehicles, caravans, marine installations, and dual battery setups. The IP67 waterproof rating confirms full protection against dust and temporary immersion, making it suited to exposed installation positions in engine bays, under-vehicle locations, and marine environments. The ignition-protected design ensures no sparking or heat generation during operation, a critical safety requirement for installation near fuel systems and in confined spaces. The 6mm studs are compatible with 8-6 or 22-6 crimp lugs for a clean and secure wiring termination.
Manual reset operation allows the circuit breaker to be reset by hand after a trip event rather than requiring replacement, providing a reusable protection solution for main power feed and sub-circuit protection in complex 12-48V DC electrical builds.
