These manual-reset thermal circuit breakers are designed for 12V DC systems and offer dependable protection across a current range of 5A to 30A. With a non-cycling design, they remain tripped until manually reset by pressing the built-in button, providing added safety and control in sensitive circuits.

Commonly used in auxiliary and accessory systems in trucks, buses, RVs, and marine environments, these breakers are a drop-in replacement for standard fuse blocks or inline fuse holders. They are color-coded by amperage rating, and each breaker clearly displays its current and voltage specs for fast identification during service or installation.

Constructed with a durable thermoplastic housing and tin-plated copper alloy internals, they’re rated to interrupt up to 2,000A in fault conditions, ensuring reliable protection in the field. The trip curve is designed to hold at 100% load for up to 60 minutes, trip within 20 minutes at 150%, and trip within 60 seconds at 200%, giving you accurate and consistent circuit protection.
