CQAU2 Series Over-Under Voltage Guard Switch
The CQAU2 series over/under voltage switch is designed by CHAC Electric to provide reliable voltage protection for AC circuits. It is suitable for use in AC 50Hz systems with a rated voltage of 230V. When installed with the COB2 circuit breaker, it offers overvoltage and undervoltage protection, safeguarding electrical equipment from damage caused by voltage fluctuations. This voltage switch ensures precise and timely protection, making it an essential component for maintaining electrical system stability and preventing equipment failure due to abnormal voltage levels.
Overview and applications
MU over voltage and under-voltage tripping device is mainly used for AC 50Hz,rated voltage 230V line and CQB2 series circuit breaker equipment made under voltage protection.
Designed by CHAC Electric, the CQAU2 over voltage and under voltage protection switch is an advanced device designed to provide robust voltage protection for alternating current (AC) circuits. This innovative switch is designed for AC systems rated at 230V and 50Hz. By integrating the CQAU2 with the COB2 circuit breaker, users gain comprehensive over voltage and under voltage protection, effectively safeguarding their electrical equipment from the adverse effects of voltage fluctuations.
The CQAU2’s capabilities are particularly pronounced when used in conjunction with the CQB2 series circuit breakers. Together, they provide a powerful defense against voltage fluctuations, ensuring electrical equipment operates within safe parameters. The CQAU2 is designed to immediately disconnect the circuit when it detects voltage levels exceeding or falling below acceptable limits, preventing potential damage to sensitive equipment.
