Frequently Asked Questions (FAQ)

What is a thermal-magnetic trip used for?

A thermal-magnetic trip protects an electrical circuit from prolonged overloads (thermal part) and sudden short circuits (magnetic part).

What is the mounting system for this circuit breaker?

This circuit breaker is mounted according to standard DIN systems, ensuring compatibility with common distribution boards.

What is the difference between rated current and breaking capacity?

Rated current is the maximum current that the circuit breaker passes under normal conditions without tripping, while breaking capacity is the maximum fault current that the circuit breaker can safely interrupt.
