Changshu Molded Case Circuit Breaker
Recommended by Dary Electric
Applications
●Low-voltage distribution protection
◆CM3, CM3E, CM3L distribution type circuit breakers can be used in AC50/60Hz TN, TT, IT distribution systems, meeting the requirements of GB50054 for the selection of electrical equipment.
◆CM3DC circuit breakers can be used in DC ungrounded, negative grounded, and center-point grounded systems, such as installed in combiner boxes and inverters for photovoltaic systems.
◆The reliable contact indication and isolation function of the full series of circuit breakers meet the requirements for isolating appliances in GB50054.
●Motor circuit protection
◆CM3, CM3E, CM3L motor protection type circuit breakers can provide overcurrent protection for motor starters, cables, and motors, with protection characteristics meeting GB14048.4 and applications meeting GB50055.
◆CM3-250C, 100C, and CM3-63 circuit breakers are only 60mm thick and can be installed in equipment control boxes to protect equipment.
●Residual current protection
◆CM3L circuit breakers provide protection against dangerous contact voltages due to insulation damage, and also provide protection against hazards such as fire caused by insulation damage, for example, insulation damage of cables.
◆CM3L circuit breakers with a rated residual operating current of 30mA can provide additional protection against direct contact for people.
●Overvoltage protection
◆CM3E circuit breakers provide overvoltage protection for the circuit, and can be used in conjunction with surge protective devices to protect equipment from damage caused by overvoltage.
●Isolation function
◆All circuit breakers have reliable contact position indication and can be used as isolating switches.
●Application environment
◆The operating ambient temperature is -5°C to +40°C, and the altitude does not exceed 2000m.
●Certifications
