Molded case circuit breakers (MCCBs) are classified into four types based on their rated ultimate short-circuit breaking capacity (LCU): Type C (Basic), Type L (Standard), Type M (High Breaking), and Type H (Ultra High Breaking). Their rated insulation voltage is 800V (500V for the JM1-63 model), suitable for low-frequency switching and low-frequency motor starting in AC systems with 50Hz and voltages up to 690V. MCCBs are equipped

Main Technical Parameters

1. The thermal motion separator of the circuit breaker has anti time limiting characteristics, and the electromagnetic separation is an instantaneous action. The characteristics are shown in the table(for distribution).

Separator Rated current (A)	Thermal motion separator(Ambient temperature+40℃)			Electromagnetic separator Action current(A)
Separator Rated current (A)	1. 05ln(Cold state) No action time(h)	1. 30ln(Cold state) No action time(h)	3. 0ln Return characteristic current Returnable time(s)
10≤In≤63	1	1	5	10ln±20%
63<In≤100	2	2	8
100<In≤800	2	2	12	10ln±20%and 5In±20%

2. For protecting electric motors(Ambient temperature 40℃)

Test current name	Current multiplier	Appointed time		Initial state
Test current name	Current multiplier	10≤In≤225	225<In≤800	Initial state
Agree not to separate current	1. 0			Cold state
Agreed separation current	1. 2			Hot state
	1. 5	<4min	<8min	Hot state
	7. 2	4s<Tp≤10s	6s<Tp≤20s	Cold state

3. The operating current of the electromagnetic separator used to protect the motor is 12In±20%(A)

4. When the external voltage of the separator is between 70% and 110%of the rated control power supply voltage, it can reliably disconnect the circuit breaker.

5. When the power supply voltage drops to within the range of 70% to 35%of the rated working voltage of the deficient voltage separator, the deficient voltage separator can reliably disconnect the circuit breaker; when the power supply voltage is lower than 35% of the rated working voltage of the under voltage separator, the under voltage separator can prevent the circuit breaker from closing; When the voltage is higher than 85%of the rated working voltage of the voltage separator, the lack of voltage separator can ensure the reliable closure of the circuit breaker.
