Pollak 54-240 40 Amp Circuit Breaker

The Pollak 54-240 is a 40-amp automatic reset circuit breaker designed for automotive, marine, RV, and powersports electrical systems. This thermal circuit breaker provides reliable overcurrent protection for 12-volt DC circuits, automatically resetting once the fault condition is cleared and the breaker cools down.

Key Features:

• 40-amp current rating for medium to heavy-duty applications
• Automatic reset design eliminates the need for manual intervention
• Thermal protection prevents damage from overcurrent conditions
• Compact mounting design with threaded stud terminal
• Suitable for 12V DC automotive, marine, and recreational vehicle applications
• Durable construction for reliable long-term performance

This circuit breaker is ideal for protecting accessory circuits, lighting systems, winches, pumps, and other electrical components. The automatic reset feature makes it particularly useful for applications where manual access may be difficult or inconvenient. Simply install inline with the circuit requiring protection, and the breaker will trip when current exceeds 40 amps, then automatically reset when the overload condition is resolved.
