Notes:

① For frame ratings 100A and 225A circuit breakers, each group of auxiliary contacts consists of one Normally Open (NO) and one Normally Closed (NC) contact. For other circuit breakers, each group consists of two NO and two NC contacts.

② For frame rating 100A, models 248, 258, 278, 348, 358, 378 are not available. For frame rating 225A, models 258 and 358 are not available.

③ Thermomagnetic release means the product has both short-circuit protection and overload protection functions.

Main Technical Parameters of Control Circuits

Category	Type	Rated Operational Voltage (V)	Rated Operational Voltage (V)	Rated Operational Voltage (V)
		AC	AC	DC
Release	Shunt Trip	Us	220/230, 380/400	24, 110, 220
Release	Undervoltage	Ue	220/230, 380/400

Note: When selecting a DC 24V specification for the shunt trip release, the rated current must be ≥ 4.5A.

Warning! For a circuit breaker equipped with an undervoltage release, closing operation is only possible when the rated voltage is applied to the undervoltage release. Otherwise, damage to the circuit breaker may occur!

Main Parameters of Auxiliary Contacts and Alarm Contacts

Conventional Thermal Current Ith (A)	Rated Insulation Voltage Ui (V)	Rated Operational Current Ie (A)	Rated Operational Current Ie (A)	Applicable Frame Rating
		AC 380V	DC 220V
1	400	0.3	0.15	For use as alarm contact
3	400	0.26	0.14	225A and below
6	400	3	0.2	400A and above

Under normal closing and opening of the circuit breaker, the alarm contact does not operate. It only changes its original state (NO becomes closed, NC becomes open) after tripping (or fault trip). After the circuit breaker is reset, the alarm contact returns to its original state.
