Pollak 54-150 50 Amp Type 1 Automatic Reset Circuit Breaker – Heavy-Duty Metal Housing

Maximize the protection of your vehicle's high-current electrical systems with the Pollak 54-150 50 Amp Circuit Breaker. Engineered for the most demanding commercial trucking, marine, and construction applications, this Type 1 "Automatic Reset" breaker is built to handle significant electrical loads that would instantly blow standard fuses.

As a Type 1 breaker, the 54-150 provides continuous protection by automatically cycling (Off-On) until an electrical fault or short circuit is resolved. This ensures that critical systems—such as high-capacity lift gates, heavy-duty winches, and auxiliary power banks—resume operation as soon as the danger has passed, without the need for manual fuse replacement. The heavy-duty metal housing provides superior heat dissipation, which is essential for 50 Amp circuits that generate higher thermal levels during operation.

Key Features:

• Type 1 Automatic Reset: Restores power automatically once the overload is cleared, minimizing downtime for essential equipment.

• 50 Amp Maximum Protection: One of the highest amperage ratings in its class for 12V DC heavy-duty applications.

• Rugged Zinc-Plated Metal Case: Built for extreme durability, vibration resistance, and superior thermal management.

• Standard Stud Terminals: Features (2) #10-32 threaded studs to ensure a secure, high-conductivity connection for heavy-gauge battery cables.

• Industry Standard: A genuine Pollak (SMP brand) component trusted by major truck OEMs for reliable circuit protection.
