First, the scope

YDM1LE series plastic shell leakage circuit breaker ( CM1LE Molded Case Circuit Breaker ), applicable to the exchange 50Hz, rated working voltage 400V, rated current up to 630A circuit, do not frequent conversion purposes. Circuit breaker with overload, short circuit and under voltage protection device to protect the circuit and power equipment from damage. Leakage protection may provide indirect protection of personal contacts. Also provides protection device leakage current due to circuit or ground fault. Molded Case leakage circuit breakers dimensions, installation dimensions and CM1 MCCB same frame degree identical.
CM1LE molded case circuit breaker according to its rated breaking capacity limit of the circuit breaker (lcu) are divided into high and low: M-type (high breaking type), H type (high breaking type) categories. The circuit breaker has small size, high segmentation, arcing short, anti-vibration characteristics.

Second, model and specification

Note:
1. handle direct operation no code, rotating operation in Z, electrically operated with P expressed;
2. only do isolated without tripping the circuit breaker to 000 means;
3. Motor protection circuit breaker 2, said power distribution with no code;
The four-pole circuit breaker neutral pole (N pole) structure code;
Type A: N pole not installed overcurrent tripping element, and N pole is always connected not with the other three poles combined points;
Type B: N pole not installed overcurrent tripping element, and the N pole and the other three poles combined points;
Type C: N pole installed current trip element, and the N pole and the other three poles combined points;
Type D: N pole installed current trip element, and N pole is always connected not with the other three poles combined points;

Third, the product features

Leakage protection module routine sampling circuit breaker operating power for the two-phase, three-phase circuit breaker in this series, if the lack of any phase, the circuit breaker can still work;
Rated residual operating current l △ n and maximum off time is adjustable according to the scene century;
When phase voltage is reduced to 50V, leakage protection module still work;
Has a leak alarm output function;
Overall size and CM1 molded case circuit breaker is installed with the same specifications, with better call sex.
