3p 4p DC MCCB Moulded Case Circuit Breaker 1500V

DC system-specific circuit breakers are used in rated insulation voltage of 1600V and a rated operating voltage of DC1500V and below, and rated operating currents of 250A and below. C ircuit breakers are mainly used for overload and short circuit protection of distributed power and protection circuits and power equipment in DC systems . U nder normal circumstances can be used as a line of infrequent conversion and DC motor infrequent start.

1.Normal conditions of use

Ambient air temperature does not exceed the upper limit of +70ºC, the lower limit of not less than -40ºC , 24-hour average does not exceed +35ºC. (Note: Circuit breakers for use in ambient air temperatures above + 70ºC or below -40ºC should be consulted with the manufacturer);
The installation site of the altitude does not exceed 2000m (2000m above the need for the corresponding derating)
The relative temperature of the atmosphere is not more than 50% at the highest temperature around +40ºC, and can be compared at a lower temperature.High relative humidity (for example, 90% at 20ºC), and the consideration of temperature change on the surface of the product dew.
2.Normal installation conditions
Installation conditions: the general should be vertical installation or horizontal installation;
Installation categories: Class III of circuit breaker main circuit, control circuit and auxiliary circuit are class II.
Pollution level: Three
3.Normal storage and transport conditions
The temperature limit is not lower than -40ºC,the upper limit does not exceed +70ºC Relative humidity (25ºC) does not exceed 95ºC;
The product should be lightly moved during transport,should not be reversed should be acoided violent collision Main technical parameters
