Heavy-duty automotive circuit protectors for adventurous vehicles

Reliable Trimax automotive circuit protectors help prevent surprises on land and sea. Whether freestyling for fun on the chop, racing code three to a four-alarm fire, or long-hauling across the continent, power loss can range from annoying to catastrophic. Don’t let a short, ground fault, overcurrent or motor lockup fry your wires! Auxiliary power and accessory circuits in hard-working vehicles need heavy-duty circuit protection.

Exciting enough!

When boring is better. Facing extreme weather, challenging terrain or heavy use, drivers press on, hoping for normal. When nothing drastic happens it’s because circuit protectors are doing their job. Trucks keeps running, lights stay on, anchors come up, lift gates lift, and millions of folks carry on safely and get their jobs done.

Flashers and lights working as expected.

Six hair-raising hours of sleet! What makes it bearable? Steady current to lights and instruments –– not to mention the auxiliary heater!

High amperage thermal circuit breakers for automotive aftermarket

Circuit protectors and circuit breakers provide resettable and reusable replacement or alternative to standard fuses or fusible links. By reacting predictably to specific voltage conditions they cut power to protect wiring, solenoids and auxiliary motors, allowing you to keep the show on the road…or off the road, if that’s where the show is!

Use in fuse blocks, wiring panels and QC mounts

• Type 1 Auto reset : Once tripped, these will reset, or cycle, as the internal elements cool, indicating normal operating state.
• Type 2 Modified reset : aka trip and hold, these remain in “open” state until removal of power allows the breaker to reset.
• Type 3 Manual reset : Internal structure and case design incorporates lever or pushbutton to reset after trip event.
