Detailed Product Description

1.JXM1 series moulded case circuit breaker

is one of products developed and manufactured by adopting international advanced technology.

It is supplied with rated insulating voltage 800V and used for circuit of A.C. 50Hz,

rated operating voltage AC 400V (or below), rated operatingcurrent up to 800A for infrequent changing over and starting of the motors.

The products con-forms to IEC60947-2 standard.

2. Main Technical Specification(table1)

3. Protection Characteristic
The thermodynamic release of a circuit breaker provides the feature of inverse time-delay,while the magnetic release is the instantaneous operation as shown on table 2(distribution cir-cuit breaker) and table 3 (motor protection circuit breaker).
