MLQ5-100/4P is a 4P PC-class Automatic Transfer Switch (ATS) with key lock design. It serves as a dual power changeover switch for two independent AC power supplies. When the main power supply fails, the ATS will automatically switch the load to standby power to guarantee uninterrupted power supply for critical electrical equipment.
This ATS adopts integrated PC-level main structure. Built-in mechanical and electrical dual interlock protection effectively prevents two power sources from being connected simultaneously to avoid short-circuit accidents. It supports automatic and manual dual operation modes. The key lock can lock the manual operating handle to prevent unauthorized operation or accidental misoperation. External control terminals are reserved for simple and tidy wiring.
