Koyann GYM1E-125 3p/4p Electronic Molded Case Circuit Breaker MCCB with IEC60947-2
Product model and meaning
The main features
1. Optional coordination: GYM1E electronic plastic case circuit breaker has a three-stage protection function. The circuit breaker of category B and other short-circuit protection devices connected in the same circuit have a selective coordination under short-circuit condition;
2. Three-stage protection operation current and operation time can be selected: the user can set and adjust the trip according to the requirements of load current;
3. Self-power supply: the electronic trip is powered by the circuit breaker itself. The current signal and the working power of the trip come from the current transformer installed in the circuit breaker;
4. With "warning" indication: When the actual operating current flowing through the circuit breaker reaches or exceeds the Iro, the "pre-alarm" LIGHT emitting diode on the cover of the circuit breaker will indicate yellow;
5. Overload indicator;When the load current exceeds the overload long delay action current, the light emitting diode on the surface cover of the circuit breaker indicates red.
6. Large-current instantaneous trip function: when the circuit breaker is closed or in operation, in case of short-circuit with large-current (≥20lnm), the circuit breaker shall be directly trip by electromagnetic trip mechanism;
7. Interchangeability in installation: the external dimensions are the same as those of conventional molded case circuit breakers.
There are three and four poles according to the number of product poles.The type of neutral electrode (N pole) of quadrupole product is: the current and time parameters of n-pole overcurrent protection automatically track the setting value of phase line by 100%, and the N pole combines with other three poles (the N pole first combines and then divides);
Rated current of shell frame: GYM1E-125;
GYM1E - 250;
GYM1E - 400;
GYM1E - 630;
GYM1E - 800;
GYM1E - 1250;
The wiring modes can be divided into five types: front wiring, back wiring, front wiring, back wiring, and drawn wiring.
There are two kinds of accessories according to whether the circuit breaker is equipped with accessories or not.
Accessories are divided into internal accessories and external accessories: the internal accessories include shunt trip, undervoltage trip, auxiliary contact and alarm contact.
The external accessories are rotary handle operation mechanism and electric operation mechanism
