Pollak 54-855PL 200 Amp Type I High Amp Circuit Breaker – 30V DC, Ignition Protected Waterproof Housing

The Ultimate Protection for High-Capacity DC Power Systems 

When your electrical system demands the highest level of overcurrent protection, the Pollak 54-855PL delivers. With a massive 200 Amp rating, this single-pole thermal circuit breaker is built for the most power-intensive applications in the heavy-duty trucking, mining, and marine industries. Rated for up to 30V DC, it serves as a rugged, resettable alternative to high-amp fuses.

Engineered for Survival in Harsh Environments 

The 54-855PL features Pollak’s signature thermoset plastic housing (UL rated 94V-0), specifically designed to solve the common failures of traditional metal breakers:

• Maximum Safety: The non-conductive body ensures that high-amperage terminals cannot accidentally short to the housing, preventing catastrophic electrical fires.

• Ignition Protected: Fully compliant with SAE J1625 and J1171 standards. It is safe for installation in battery compartments, engine bays, and marine engine rooms where explosive vapors may be present.

• Corrosion & Vibration Proof: The surface-mount design and rust-proof housing make it the ideal choice for chassis-mounted power distribution and saltwater marine environments.

Type I Automatic Reset (Cycling) Performance 

The Type I auto-reset functionality is critical for high-load systems. If an overload occurs, the breaker trips to protect the wiring and automatically resets once the internal thermal element cools. This is essential for maintaining power to critical systems like heavy-duty lift gates or winches without needing to manually reset a switch in a hard-to-reach location.

Typical Applications:

• Main power protection for 3000W+ Power Inverters

• Commercial-grade winches and recovery gear

• Heavy-duty hydraulic lift motors and snowplow systems

• Main DC bus protection for RVs and large yachts

• Emergency vehicle master power distribution
