Pollak 54-550 50 Amp Type 1 Automatic Reset Circuit Breaker – Metal Housing with Straight Bracket

Provide maximum circuit protection for your heavy-duty equipment with the Pollak 54-550 50 Amp Circuit Breaker. This high-capacity, Type 1 "Automatic Reset" breaker is the industry standard for safeguarding high-draw 12V DC systems. Featuring a pre-installed straight mounting bracket, the 54-550 is designed for a secure, flush-mount installation on firewalls, interior panels, or along chassis rails where space and durability are paramount.

The 54-550 is encased in a rugged metal housing, engineered to provide the superior heat dissipation required for 50 Amp loads. This industrial-grade construction ensures long-term reliability in the high-vibration environments of commercial trucking, construction, and agricultural machinery. As a Type 1 breaker, it automatically cycles and resets once an electrical fault or overload is cleared, ensuring that essential high-draw components—such as large hydraulic pumps, heavy-duty winches, and primary power feeds—return to operation without the need for manual fuse replacement.

Key Features:

• Integrated Straight Bracket: Right-angle mounting tab is replaced with a flat, straight bracket for easy flush-mount installation on flat surfaces.

• Type 1 Auto-Reset Functionality: Automatically restores power to the circuit once the overload condition is corrected, maximizing vehicle uptime.

• 50 Amp High-Capacity Protection: Designed to handle the heaviest electrical loads in 12V DC vehicle applications.

• Heavy-Duty Metal Case: Zinc-plated steel housing offers industrial-grade durability and efficient thermal management.

• Vibration-Proof Stud Terminals: Features (2) #10-32 threaded studs to ensure a permanent, high-torque connection with heavy-gauge ring terminals.
