This is a 20‑amp thermal circuit breaker used to protect 12 V DC electrical circuits in heavy‑duty trucks, trailers, and other vehicles.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It trips automatically when the current exceeds its rating, preventing overheating and damage to wiring and components, then resets either automatically or when the fault is cleared. Replace yours if it fails to reset or keeps tripping under normal load. It’s commonly found in accessory, lighting, and auxiliary power circuits.
