2TC2 25 AMP BREAKER

2TC2 25 Amp Circuit Breaker – Top-Rated 2TC2 Breaker for Primary Auxiliary Circuit Protection

The 2TC2 25 Amp Circuit Breaker is the highest current-rated breaker in the compact 2TC2 series – designed for the most demanding auxiliary circuit protection requirements just below the threshold of the larger 3TC7 series breakers. At 25 amps, this breaker is the correct specification for primary auxiliary supply circuits, high-demand motor feeds, and high-current accessory circuits in professional motorsport electrical builds across Norway, Sweden, and Denmark.

25 Amp: The Transition Point Between Auxiliary and Primary Protection

The 25 amp 2TC2 occupies a specific and important position in the circuit protection hierarchy of a motorsport electrical system. It covers circuits that exceed the 20 amp auxiliary range but do not yet warrant the full 3TC7 series breaker – primary electric fan circuits on smaller-displacement engines, high-specification fuel pump feeds, primary relay supply circuits for multi-relay boards, and main power feed protection for complex ECU and data logging systems that draw substantial but not primary-level current in race car builds.

Completing the 2TC2 Range

The 25 amp 2TC2 completes the compact breaker range alongside the 3, 5, 7.5, 10, 15, and 20 amp variants from Arctic Performance Parts. Provides seamless current coverage from the lightest control circuits to the heaviest auxiliary loads for motorsport builds on Mazda RX-Series, turbocharged performance cars, and competition vehicles throughout Norway, Sweden, and Denmark.
