Pollak 54-125P 25 Amp 12V Circuit Breaker with Metal Base

The Pollak 54-125P is a single pole thermal Type I circuit breaker designed for reliable overcurrent protection in 12V DC electrical systems. This heavy-duty circuit breaker features a 25 amp current rating and automatic cycling reset functionality, making it ideal for auxiliary and accessory circuits in trucks, buses, RVs, marine applications, battery chargers, and DC audio systems.

Key Features:

• 25 DC amp current rating at 12 VDC
• Type I cycling circuit breaker with automatic reset
• Durable metal base construction
• Includes 90° mounting bracket for easy installation
• Operating temperature range: -10°F to 150°F (-23°C to 65°C)
• Storage temperature range: -20°F to 200°F (-29°C to 93°C)
• Complies with SAE Standard J553
• Packaged for easy handling and installation

The Type I design automatically cycles during overcurrent conditions. When an overload occurs, the composite alloy material bends to separate the contacts, then returns to run mode as it cools. This cycling continues until the overcurrent source is removed or corrected, providing continuous protection without manual intervention.
