FAQ

What does the “C Curve” rating mean for this C60H-DC breaker?

A C-curve rating indicates that the breaker will trip instantaneously at 5 to 10 times its rated current (6A). This makes it suitable for circuits with moderate inrush currents, such as small motors, transformers, and lighting systems, preventing nuisance tripping while still providing effective protection.

Is this MCB suitable for AC applications, or only DC?

This breaker is specifically designed and rated for DC (Direct Current) applications, as indicated by the “DC” in its model name. Using it in an AC circuit is not recommended as its arc extinguishing mechanism is optimized for DC, and it may not perform safely or reliably under AC fault conditions.

What is the significance of the IEC/EN 60947-2 standard it complies with?

Compliance with IEC/EN 60947-2 means the circuit breaker is suitable for industrial applications, which have more stringent requirements for performance, reliability, and safety than residential standards. It ensures the device has been tested for higher breaking capacities and operational endurance.
