CE RoHS Approved 3p Molded Case Dual Power Switch for Industrial Use

The molded case dual power switch supports various combination modes such as mains - generator and mains - UPS, but attention should be paid to: the generator start signal needs to be linked with the switch (delay 0 - 30s adjustable); surge protection should be configured at the input / output end of UPS to avoid equipment damage caused by overvoltage during switching.

You need to provide us with the following detailed information: product name, model, specification, quantity, etc.

PC-class is suitable for scenarios where power interruption is not allowed (such as hospital operating rooms, data centers), focusing on fast switching (50-250ms), and requires external short-circuit protection devices (fuses or circuit breakers). CB-class is suitable for scenarios requiring short-circuit protection (such as industrial production lines), integrating circuit breaker functions, but the switching time is longer (2000-3000ms). You can choose according to actual needs and the charact

It is recommended to be installed by certified electricians. When wiring, be sure to ensure that the neutral wire (N) is correctly connected to the phase wire to avoid misjudgment by the frequency converter. At the same time, an isolating switch must be configured at the incoming end to meet the safety requirements during maintenance and ensure the personal safety of operators.

Test the switching function monthly, clean the dust on the shell, and check whether the contacts are oxidized. Each year, the manufacturer's engineers will calibrate the mechanical interlock, upgrade the frequency converter program, and replace worn parts.
