Pollak 54-854PL 120 Amp Type I High Amp Circuit Breaker – 30V DC, Ignition Protected Plastic Housing

Heavy-Duty Electrical Protection for High-Current Systems 

The Pollak 54-854PL is a high-capacity, 120 Amp single-pole thermal circuit breaker designed to safeguard sophisticated electrical systems in heavy-duty vehicles and marine craft. Rated for up to 30V DC, this breaker provides a critical fail-safe for accessory circuits, ensuring that overcurrent events don't lead to permanent damage or costly downtime.

The Advantages of the Pollak PL Series Housing 

Engineering for the trucking and marine industries requires components that can withstand extreme environments. The 54-854PL is housed in a high-grade thermoset plastic (UL rated 94V-0), offering significant benefits over standard metal breakers:

• Ignition Protected: Meets SAE J1625 and J1171 standards, making it safe for use in engine compartments, battery rooms, and near potential fuel vapors.

• Corrosion & Weather Resistance: The plastic body is naturally immune to rust and is designed to be splash-proof and dust-proof for long-term reliability in exposed chassis or deck mounts.

• Safe Isolation: The non-conductive housing prevents accidental "housing shorts," a common failure point in metal breakers where loose wires can touch the outer casing.

Reliable Type I Automatic Reset 

Featuring Type I (Cycling) reset technology, the 54-854PL automatically resets once the internal thermal element cools following a trip. This functionality is vital for critical circuits where manual access is difficult, allowing the system to restore power as soon as the overload condition is cleared.

Typical Applications:

• Primary power for large DC-to-AC Inverters
