TOMC3-63 AC 3P 40A MCB Mini Circuit Breaker
AC 3P 40A MCB TOMC3-63 uses the new reference in final distribution, and has absolute safety of circuit protection. It is with greater continuity of service, simple to choose with meaningful part numbers.
AC 3P 40A MCB TOMC3-63 is easy to install with quick, ergonomic & safe terminal shutters & robust connections (twice the standard tightening torque).
Also, it is environmentally friendly with 100% recyclable & recoverable materials.
AC 3P 40A MCB Special Tips
1. MCB is for non-professional operation by those untrained, and no maintenance is required.
2. Satisfying conditions and applications as mentioned above, MCB with “ON-OFF” indicating device is considered suitable for isolation function.
3. Appropriate tripping curve being chosen and properly installed, MCB trips and switches off its protected circuit in case of fault, and thus provides protection against electric shock.
4. B, C, D tripping curve(see graphics 1):
