FAQ

What is the main application for a C-curve DC circuit breaker like this one?

A C-curve breaker is designed for circuits with moderate inrush currents, such as small motors, transformers, and lighting circuits. It provides excellent protection against both overload and short-circuit conditions in these common DC applications.

Does the C60H-DC require a specific polarity for connection?

Yes. As indicated by the ‘DANGER’ warning and the L+/- markings on the device, correct voltage polarity is required for safe and effective operation. Always connect the positive line to the terminal marked ‘+’ and the negative line to the terminal marked ‘-‘.

What is the rated impulse withstand voltage (Uimp) and why is it important?

The Uimp of 6kV indicates the maximum voltage surge the breaker can withstand without damage, typically from events like lightning strikes or switching surges. A higher Uimp rating signifies greater durability and reliability in electrically noisy environments.
