400 Amp Three Phase Automatic Transfer Switch Ats

400 amp three phase automatic transfer switch ats is a high capacity power switching device designed for three-phase electrical systems. It continuously monitors the status of two power sources and automatically transfers critical loads between them during outages, voltage anomalies, or phase failures, ensuring uninterrupted power for industrial, commercial.

Features:

1.400A high current design, suitable for large power motors, water pumps, central air conditioning systems, computer rooms, etc.

2.Integrated structure, stable and reliable operation, resistant to vibration and interference

3.Digital controller, adjustable parameters, applicable to different power grids and generator scenarios

4.Three-phase four-wire 4P structure, zero line synchronous switching to prevent zero point drift and damage equipment

5.Compact in size, suitable for standard distribution cabinet installation

6.Applicable to important places such as industry, commerce, hospitals, data centers, and fire emergency situations

FAQ:

Q:How can I ensure that the 400 amp three phase automatic transfer switch ats is compatible with my existing generator?

A:There are three points can be determined if the ats is suitable with your generator.

1.Confirm that the generator output is also 400A, three-phase (or higher, ATS should be equal to or slightly greater than the generator's rated current)

2.Confirm the voltage level (208V, 480V, 600V, etc.) and phase (3-phase 4-wire or 3-phase 3-wire)

3.Confirm the generator brand and control method (two-wire start or three-wire start) to ensure that the control logic is compatible

Q:What is the enclosure protection rating (NEMA)?

A:This depends on where you install it.If you install it indoor, then usually is NEMA1 rating,which means it is only dust-proof.If installed outdoors, it is usually of NEMA 3 rating, which means it is waterproof and resistant to snow and ice.Furthermore, we can offer NEMA 4/4X standards for special environments such as chemical plants and coastal areas, which ensure waterproof and corrosion-resistant properties.
