Residual leakage MCCB SZRM1LSZRM1L series Molded Case leakage circuit breaker (CBR) (hereinafter referred to as breaker), rated insulation voltage of 690V, suitable for AC 50Hz or (60Hz), rated working voltage 400V, rated operating current to 800A circuit do not frequent conversion and infrequent start motor used. Circuit breaker with overload, short circuit and under-voltage protection function Ho, can protect the circuit and power equipment from damage low voltage switch cabinet role, but also can not be detected in this current protection dangerous fire out of the ground fault may cause long-term presence of provide protection. ◆ circuit breaker has small size, high breaking capacity, short arcing, anti-vibration characteristics; ◆ breaker can be installed vertically (ie, vertical loading), can also be installed horizontally (ie horizontal installation); ◆ breaker with isolation function, the corresponding symbol; ◆ breaker in line with standard; good: IEC60947-2, GB14048.2-2001. GCS-0.4 standard low-voltage cabinet detailed framework using C sections and beams are assembled with high strength. Easy modular installation features, frameworks and components by the mounting holes modulus E = 20mm change drawer types are divided into 8E / 2,8E, 12E, 16E, 20E, 24E, 6 个 size series, circuit rated current 400A and below. cabinet with drawers mainly low voltage, both withdrawable and fixed, can be mixed portfolio, any Selection; between functional units are separated between compartments clear, reliable and low voltage switch cabinet, not due to failure of a unit of work and affect other units, so that a minimum level of fault confined to the main bus cabinet level position and after use. the external cables in the cable chamber is completed, the cable can be up and down and out, easy installation and maintenance. economy on the basis of the standard, remove the boards, and to make the cabinet more economical and practical, after qualifying mode to qualify for easy cabling and maintenance Main bus, vertical busway and connectors products by GCK arrangement, both to ensure product performance, but also reduce the cost of the product, so that products meet the economic, practical and beautiful. cabinet protection rating of IP30,40 . the role of low voltage switch cabinet, low voltage, provided by the Henan Xi Xi Connaught Electrical and Mechanical and Electrical Equipment Co.
