Magnetic release
An electromagnet with plunger ensures instantanueous
tripping in case of short circuit. The IEC60898
distringuishes three different types: B, C, D
And the IEC60947standard leaves the calibration of
magnetic release to manufactures decision.
Thermal release
The release is initated by a bimetal strip in case of
overload, the standard defines the range of release
for specific overload value
Referece ambient temperature is 30ºC
Temperature derating
The maximum permissible current in a circuit breaker on the ambient temperature where the circuit breaker is placed.
Ambient temperature is the temperature inside the enclosure or enclosure or switchboard in which the circuit breakers
are installed
The reference temperature is 30 Cº
