Pollak 54-853PL 80 Amp Type I High Amp Circuit Breaker – 30V DC Surface Mount, Ignition Protected

High-Amperage Circuit Protection for Demanding Electrical Systems 

The Pollak 54-853PL is a professional-grade, 80 Amp thermal circuit breaker engineered to handle the heavy electrical loads found in commercial trucking, marine, and recreational vehicle applications. Operating up to 30V DC, this single-pole breaker provides a robust safety barrier for your vehicle’s most critical power circuits.

Built for the Long Haul: Thermoset Plastic Housing 

Designed to outperform traditional metal breakers in harsh environments, the 54-853PL features a premium thermoset plastic housing (UL rated 94V-0). This construction offers:

• Superior Insulation: The non-conductive body eliminates the risk of external short-circuiting.

• Environmental Resilience: The housing is splash-proof and dust-proof, making it ideal for engine compartments or exposed mounting locations.

• Vibration Resistance: The surface-mount design ensures a stable connection that won't loosen under the constant vibration of heavy-duty diesel engines.

Smart "Type I" Automatic Reset 

Equipped with Type I (Cycling) reset technology, this breaker automatically resets once the internal thermal element cools down after a trip. This ensures that essential systems—like lift gates, winches, or auxiliary lighting—return to operation as soon as it is safe, without the need for manual intervention or fuse replacements.

Typical Applications:

• Heavy-duty truck auxiliary power circuits

• Boat and marine trolling motors

• RV battery charging systems and solar arrays
