Plastic and Metal Auto Circuit Breaker with Red Cover

Auto Circuit Breakers with Red Cover — Plastic & Metal Body | 5A to 50A+

Solid, no-fuss circuit protection for automotive, 4WD, marine, caravan, and trailer wiring.

The bright red protective cover keeps terminals safe from accidental contact, moisture, and debris — critical in underbonnet, under-chassis, and exposed outdoor installations.
