CAW1-2000/1250A fixed type series intelligent circuit breaker (hereinafter referred to as breaker) is suitable for the

circuit of AC 50/60Hz with rated voltage 400V, 690V and rated current 1250A .It is

mainly used to distribute electric energy and protect circuit and power supply equipment

from overload, under-voltage short-circuit ,and single-phase earthing .With intelligent and

selective protection functions, the breaker can improve the reliability of power supply, and

avoid unnecessary power failure . The breaker is applicable for power stations, factories ,

mines(for 690V) and modern high-building, especially for the distribution system of intelligent

building. The breaker conforms to IEC60947-2. The whole series have past CCC certification.

Accessories

Shunt release

a. Shunt release is for remote breaking of circuit breaker so as to enhance security of the operator

b. Ratings of shunt release

Under-voltage release

a. It is an optional accessory;

b. Mainly used to protection apparatus from damage due to lowering of the operational voltage to a certain value;

c. Two types of release are available: instantaneous release and time-delay release;

d. For breakers appended with the release, it should be electrified continuously;

e. Ratings of under-voltage release

Category		Under-voltage time-delay release	Under-voltage instantaneous release
Operation time of the release		time-delay: 1s, 3s, 5s	instantaneous
Operational voltage of the release	35%U_s~70%U_s	Break the breaker	Break the breaker
	≤35%U_s	Can not make the breaker	Can not make the breaker
	≥85%U_s~110%U_s	Reliably make the breaker	Reliably make the breaker
Within ½ delay time, voltage of power supply recovers to 85% U_s		Can not trip the breaker

Note: Error the time of time-delay is ±10%

Closing electro-magnet

a. The magnet is for remote making of circuit breaker so as to enhance security of the operator.

b. The magnet could not be electrified for a long time.

c. Rating of the magnet.

Auxiliary Contact

a. Conventional heating current of auxiliary contact: 6A

b. Auxiliary contacts: 4NO+4NC, 3NO+NC, 5NO+5NC (customization)
