GXM1 Series Plastic Case Circuit Breaker
GXM1 Series Plastic Case Circuit Breaker
I.Use
GXMl series plastic case circuit breaker (hereinafter referred to as circuit breaker), rated insulation voltage 400V (shell rated current rated below 160A), 690V (shell rated current 250A and above), mainly suitable for AC 50Hz. In the distribution network with rated current up to 800A and rated working voltage of 400V, it is used to distribute electric energy, protect the overload, short circuit and under voltage of the line and power equipment. A circuit breaker with a rated current of 400A or less is connected in series with a contactor between the circuit breaker and the motor to indirectly protect the motor from overload, undervoltage and short circuit. Under normal conditions, it can also be used as an infrequent conversion of the line.
This series of circuit breakers can be installed vertically. It can also be installed horizontally.
II.Model meaning
Note:
(1) The circuit breaker for power distribution has no code, and the protection motor is indicated by 2.
(2) The handle is operated directly without a code; Z—rotary handle operation; Z1—central, Z2—eccentric; D—motor operation.
(3) S—low breaking type, H—high breaking type.
The release type and accessory selection code are shown in the table below.
Two sets of auxiliary contacts and one alarm contact 268/368/468 are only for circuit breakers with Inm≥630A.
III.The main technical parameters are shown in the following table 2
