## Description

Dual Power Automatic Transfer Switch AC 400V 4P 100A ATS PC Automatic Changeover Toggle Switch Double Transfer Switch for Municipal Electricity, UPS, Inverter, Solar

## Features

- Scope of application of backup power supply: This product is a dual-power automatic transfer switch for photovoltaic models. Unlike the mains model, which can only be connected to mains or generators, this product can be connected to UPS, inverter, solar energy, and photovoltaic as a backup power supply.
- Rapid switching: The switching response time of the transfer switch is ≤0.05 (S). When the normal power supply is abnormal, the backup power supply will work immediately, and the power supply will be switched in milliseconds without interruption, ensuring the continuity, reliability and safety of the power supply.
- Technical parameters: Rated control voltage Us: AC220 V 50Hz; Rated current: 100A; Rated voltage: 400V AC; Insulation voltage: 690V AC; Rated frequency: 50Hz/60Hz; Rated short-circuit current: 50kA; Rated impulse withstand voltage: 8kV; Service life: Electrical: 2000 times; Mechanical: 5000 times.
- Flame-retardant material: Made of high-quality flame-retardant plastic material, it has good insulation, high temperature resistance, aging resistance, safety and reliability. The use of silver contacts can greatly improve the conductivity and longevity of the product.
- Applicable places: The emergency switch has a built-in timed standby open signal output port, which can be connected to an external signal indicator, which is convenient for observation outside the cabinet. 35mm guide rail installation design. It is widely used in various places where continuous power failure is not allowed, such as factories, shopping malls, nurseries, etc.
