Value Collection CB155-20 Plug-in Circuit Breaker 20 Amp

Product Description

The VALUE COLLECTION CB155-20 is a heavy-duty plug-in circuit breaker rated at 20 amps, designed for automotive electrical systems. It provides overcurrent protection by interrupting the circuit when current exceeds the rated amperage, helping prevent wire damage and electrical fires in vehicle wiring harnesses. The plug-in mount design allows for fast, tool-free installation in compatible fuse and breaker blocks. At 0.83 inches long, 0.418 inches wide, and 0.7 inches high, it fits into tight panel spaces common in automotive and light equipment electrical layouts. Licensed automotive electricians and experienced vehicle technicians are the typical installers.

This circuit breaker is suited for 12-volt and 24-volt DC automotive and light-duty equipment applications where a resettable overcurrent device is preferred over a standard fuse. Common install scenarios include aftermarket accessory circuits, trailer wiring panels, marine vessel DC panels, and fleet vehicle upfit work. Its plug-in mount style makes it a direct-fit replacement in breaker blocks that accept this form factor without additional hardware.

Key Features

• 20-amp working amperage rating for automotive circuit protection
• Plug-in mount for tool-free installation in compatible breaker blocks
• Compact form factor at 0.83 x 0.418 x 0.7 inches for tight panel fitment
• Heavy-duty construction suitable for demanding automotive environments
• Resettable design eliminates the need for fuse replacement after a trip event

Compatibility

Designed as an OEM-style replacement or upgrade for automotive and light equipment electrical panels that accept plug-in style circuit breakers in the 20-amp class.

Installation Notes

Installation should be performed by a qualified automotive electrician or vehicle upfitter. Disconnect the vehicle battery before servicing any circuit protection components to prevent arcing or accidental circuit activation. Verify the breaker block accepts the plug-in form factor and that the circuit amperage load does not exceed the 20-amp rating. Follow applicable SAE and NFPA 303 guidelines when installing in marine environments.
