iALM1 series molded case circuit breaker (hereinafter referred to as circuit breaker) is one of the new circuit breakers developed by adopting international advanced design technology. ltis classified into type L (standard type) according to its rated limit short-circuit breaking capacity(lcu), type M (high breaking type), and type H (high breaking type). The product has the characteristics of small volume, high breaking capacity, short arcing, and anti-vibration. it is an ideal product for land and ship use. its rated insulation voltage is 800V (500V for iALM 1-63), which is suitable for infrequent line conversion and infrequent motor startup in circuits with AC 50Hz uncrated working voltage of 690V and below. This series of circuit breakers has an overload. shortcircuit and Undervoltage protection devices, which can protect lines and power supply equipment from damage
This series of circuit breakers can be installed vertically (i.e. upright) or horizontally (i.e.transversely).
◆Ambient air temperature
◇The upper limit of ambient air temperature is +40°C; the lower limit of ambient air temperature is -5°C; the average value of ambient air temperature for 24h shall not exceed + 35°C
◇Altitude: the altitude of the installation site shall not exceed 2000m.
◇The relative humidity of the atmosphere shall not exceed 50°C when the ambient air temperature is +40°C; it can have higher relative humidity at lower temperatures;
◇The monthly average maximum relative humidity in the wettest month is 90%, and the monthly average minimum temperature in that month is +25°C, and the condensation on the product surface due to temperature change should be taken into.
◇Pollution level: Level 3.
