Pollak 54-831PL 30 Amp Type I Plastic Circuit Breaker – 24V DC with 90° Bracket

Reliable Overcurrent Protection for Heavy-Duty Electrical Systems

The Pollak 54-831PL is a high-performance, single-pole thermal Type I circuit breaker designed to provide dependable protection for 24V DC systems. Featuring a 30 Amp rating and a cycling automatic reset mechanism, this breaker ensures your vehicle’s critical electrical components remain functional without the need for manual intervention after a temporary overload.

Why Choose the Pollak Plastic Housing Series?

Unlike traditional metal-housed breakers, the Pollak 54-831PL is engineered with a one-piece molded plastic housing. This innovative design offers three distinct advantages:

• Vibration Resistance: The integrated 90-degree mounting bracket is part of a single-mold design, making it significantly less prone to loosening or failure due to road vibration compared to spot-welded metal alternatives.

• Enhanced Safety: The non-conductive plastic body eliminates the risk of terminal wires shorting out against the housing if they become loose.

• Corrosion-Free & Lightweight: The nylon housing is lighter than metal and naturally resistant to the harsh environmental conditions found in trucking and marine applications.

Typical Applications:

This heavy-duty breaker is ideal for use in trucks, buses, RVs, and trolling motors. It is commonly used to protect accessory circuits, including:

• Headlamps and Tail Lamps

• Battery Chargers

• Door Locks and Window Lifts

• Cooling Fans and Sunroofs
