Pollak 54-540PL 40 Amp Type 1 Automatic Reset Circuit Breaker – Plastic Housing with Straight Bracket

Protect your vehicle’s high-amperage electrical systems with the industrial-grade Pollak 54-540PL 40 Amp Circuit Breaker. This Type 1 "Automatic Reset" breaker is a robust, reusable alternative to standard fuses, engineered to automatically restore power once an electrical overload or short is cleared. Featuring a pre-installed straight mounting bracket, the 54-540PL is designed for a professional, flush-mount installation on firewalls, chassis rails, or exterior panels.

The 54-540PL is uniquely constructed with a high-impact, non-conductive plastic housing that is 100% rust-proof. This makes it the premier choice for salt-spreader trucks, marine vessels, and agricultural equipment where metal breakers are prone to rapid corrosion and failure. With a 40 Amp rating, it provides reliable primary protection for heavy-duty 12V DC loads, such as hydraulic pumps, large cooling fans, power tarp systems, and auxiliary battery charging circuits.

Key Features:

• Integrated Straight Bracket: Designed for flush-mounting, providing a secure, low-profile attachment to any flat surface.

• Type 1 Auto-Reset Functionality: Automatically cycles and resets after an overload is resolved, ensuring your equipment returns to service without manual intervention.

• Corrosion-Proof Plastic Body: Non-conductive and rust-resistant housing offers maximum durability in wet, salty, or chemically harsh environments.

• 40 Amp Heavy-Duty Protection: Rated for 12V DC systems; optimized for high-draw auxiliary motors and electrical accessories.

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