Robust Circuit Protection with Integrated Mounting Support
The Pollak 54-931 30 Amp Sealed Circuit Breaker provides superior electrical protection for heavy-duty vehicles, combining high-amperage capacity with a rugged, installation-ready design. Equipped with a built-in mounting bracket, this model is engineered for secure attachment to firewalls, frames, or panels, making it the ideal choice for professional-grade installations in trucks, buses, and RVs.

Built for the Toughest Environments
Designed specifically for "exposed applications," the 54-931 is sealed to resist moisture, dust, road salt, and oil. The integrated 12-inch wire loop allows for maximum wiring flexibility; simply cut the loop to create two custom leads for splicing into your electrical system. As a Type I Automatic Reset breaker, it provides continuous protection by cycling during an over-current event and automatically resetting once the fault is cleared, ensuring your critical systems stay powered without manual resetting.

Key Features & Benefits:

• Automatic Reset (Type I): Continuous cycling during faults and automatic recovery once the overload is removed—perfect for mission-critical lighting and motor circuits.

• Sealed Weatherproof Design: Protective housing guards internal components against corrosion and debris in exterior or under-hood locations.

• Integrated Mounting Bracket: Includes a pre-attached metal bracket for fast, secure, and stable mounting in high-vibration environments.

• 12-Inch Wire Loop: Provides ample lead length to customize your connections, eliminating the need for additional terminal hardware.
