2TC2 5 AMP BREAKER

Description

2TC2 5 Amp Circuit Breaker – Low Current Resettable Breaker for ECU and Electronics Circuit Protection

The 2TC2 5 Amp Circuit Breaker is a low current push-to-reset circuit breaker for the protection of ECU power supply circuits, dash display feeds, sensor signal system power, and other low-current electronics in professional motorsport electrical builds. The 5 amp rating provides correctly proportioned overcurrent protection for the electronics tier of a race car electrical system – protecting sensitive hardware from fault currents while providing the resettable convenience that motorsport conditions demand across Norway, Sweden, and Denmark.

5 Amp Protection: The Electronics Power Supply Tier

A 5 amp breaker is the typical specification for direct ECU power supply protection, standalone lambda controller feeds, shift light and display unit power circuits, aftermarket gear position sensor power, and other standalone electronics modules that draw a defined, stable current in normal operation. The 5 amp rating is high enough to accommodate brief inrush currents during power-up without nuisance tripping, while low enough to provide meaningful protection against sustained fault currents that could damage sensitive motorsport electronics.
