Description

Overview

15 amp automatic reset circuit breaker protects vehicle and trailer electrical circuits from overload and short circuit damage. This plastic automatic reset style suits smaller accessory circuits where the breaker needs to restore power after cooling, instead of being replaced like a fuse.

Features

• 15 Amp rating for low to medium current circuit protection.
• Automatic reset operation restores the circuit after the breaker cools.
• Plastic automatic reset breaker body for compact electrical installations.
• 51 x 21mm size suits tight wiring areas and small circuit protection layouts.

Compatibility and Fitment

Match the 15 Amp rating to the circuit load, cable size and connected accessory before ordering. The main mistake is fitting a breaker that is too large for the cable or device, which can leave the wiring under-protected, or choosing automatic reset where manual fault isolation would be safer.

Compliance and Safety

Mount the breaker securely, keep terminals protected from accidental contact, and route wiring away from heat, sharp edges and moving parts. If the breaker keeps cycling, inspect the circuit for overload, short circuit, damaged insulation or incorrect cable size before returning the trailer or vehicle to service.

Trailer Applications

Workshops use 15 Amp automatic reset plastic circuit breakers for accessory feeds, small control circuits, lighting support circuits, auxiliary wiring, switch panel feeds and general trailer electrical repairs where resettable protection is preferred.
