Overview
DLM1LE Series Moulded Case Circuit Breaker With Leakage Protection (hereinafter referred to as Circuit Breakers), mainly applicable to AC 50Hz, rated AC400V, insulation voltage up to 800V in the power distribution network, used to provide indirect contact protection for people, but also can be used to prevent fire hazards due to damage to the insulation of the equipment, the generation of ground fault current caused by the fire hazard, and can be used to distribute power, protect the line and the power supply equipment overload and short circuit. It also can be used as infrequent conversion of the line and motor infrequent startup.
Conventional leakage protection module with residual current protection circuit breaker working power sampling for two-phase, this series of circuit breakers for three-phase, if the lack of any one phase, circuit breaker leakage protection module can still work normally; Rated residual action current IΔn and the maximum disconnection time according to the actual situation of the site can be adjusted; when the phase voltage is reduced to 50V, the leakage protection module is still working normally. And the product has a leakage alarm output function.
Products comply with: IEC60947, GB14048.2 standard.
Product Model
Product use and installation conditions
- The upper limit of the ambient air temperature does not exceed +40°C and the lower limit does not fall below – 5°C , the average value in 24h does not exceed + 35°C .
Note:Circuit breakers used in conditions where the ambient air temperature is higher than + 40°C or lower than – 5°C should be negotiated with the manufacturer. - The height of the poster at the installation site does not exceed 2000m;The relative temperature of the atmosphere should be discussed with the manufacturer.
- The relative temperature of the atmosphere does not exceed 50% at a maximum ambient temperature of + 40°C ;Higher relative humidity (e.g. 90% at 20°C) is possible at lower temperatures, taking into account condensation on the product surface occurring as a result of temperature change.
- Installation conditions: Vertical installation is generally required, but horizontal installation is also possible.b) Installation category:
- Circuit breaker main circuit class I, control and auxiliary circuits are class I.
- Pollution level: Class 3.
- External magnetic field: the external magnetic field in the vicinity of the installation place shall not exceed 5 times of the geomagnetic field in any direction.
