Rated voltage Ue; rated current In; overload protection (Ir or Irth) and short circuit protection (Im) trip current setting range; rated short-circuit breaking current (industrial circuit breaker Icu; household circuit breaker Icn). -Dongguan Xunwang Hardware Products Factory

Rated operating voltage (Ue): This is the voltage at which the circuit breaker operates under normal (uninterrupted) conditions.

Rated current (In): This is the maximum current that the circuit breaker with a special overcurrent trip relay can withstand at the ambient temperature specified by the manufacturer. It does not exceed the temperature limit specified by the current receiving component. value. -Dongguan Xunwang Hardware Products Factory

Short-circuit relay trip current setting value (Im)

Short-circuit trip relay (instantaneous or short delay) is used to quickly trip the circuit breaker when a high fault current value occurs. Its trip limit Im:

Rated short-circuit breaking capacity (Icu or Icn)

The rated short-circuit breaking current of the circuit breaker is the highest (expected) current value at which the circuit breaker can be disconnected without being damaged. The current value provided in the standard is the root mean square value of the AC component of the fault current. The DC transient component (which always appears in the worst case short circuit) is assumed to be zero when the standard value is calculated. Industrial circuit breaker ratings (Icu) and household circuit breaker ratings (Icn) are usually given in kA rms.
