Product Description

Product Introduction
Scope of Application:
HMKM1L Series Moulded Case Leakage Circuit Breaker (CM1L Moulded Case Leakage Circuit Breaker) Intelligent circuit breaker, intelligent leakage circuit breaker, suitable for infrequent switching in circuits with AC 50Hz, rated working voltage 400V, and rated working current up to 630A. The circuit breaker has overload, short circuit, and undervoltage protection devices to protect the circuit and power supply equipment from damage. Leakage protection can provide indirect contact protection for the human body. It can also provide protection against leakage currents or ground faults from line equipment. The overall dimensions and installation dimensions of the molded case leakage circuit breaker are completely the same as the same housing level of the CM1 molded case circuit breaker.

HMKM1L series moulded case leakage circuit breakers are divided into two types according to their rated limit circuit breaker breaking capacity (lcu): M-type (high breaking type) and H-type (high breaking type). The circuit breaker has the characteristics of small size, high segmentation, short flashover, and vibration resistance.

Model and Specification of HMKM1L Series Moulded Case Leakage Circuit Breakers
Note:
1. There is no code for direct operation of the handle, and rotation operation is represented by Z, while electric operation is represented by P;
2. Circuit breakers without release that are only used for isolation are indicated by 000;
3. The circuit breaker for protecting the motor is represented by 2, and there is no code for power distribution;
4. Structure code of neutral pole (N-pole) of four-pole circuit breaker.

Type A: The N-pole is not equipped with an overcurrent release element, and the N-pole is always connected without closing and opening
with the other three poles;
Type B: The N-pole is not equipped with an overcurrent release element, and the N-pole is closed and opened together with the other 3 poles;
Type C: The N-pole is equipped with an overcurrent release element, and the N-pole is closed and opened together with the other 3 poles;
Type D: The N-pole is equipped with an overcurrent release element, and the N-pole is always connected without closing and opening
with the other three poles

Product Features of HMKM1L Series Moulded Case Leakage Circuit Breakers
The working power supply of the leakage protection module of conventional circuit breakers is sampled as two phases, and this series of
circuit breakers
are three-phase. If any phase is missing, the circuit breaker can still operate normally.
The rated residual operating current l △ n and the maximum outage time can be adjusted on site according to century conditions;
When the phase voltage decreases to 50V, the leakage protection module can still operate normally;
With leakage alarm output function;
The appearance and volume are the same as those of the CM1 molded case circuit breaker, which is installed with the same specifications and
has good appeal
