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).
