315A 4-Pole ATS Automation Control Cabinet for Th | RFQ Sourcing Details

Product overview This 315A 4-pole automatic transfer switch (ATS) control cabinet is intended for low-voltage, three-phase four-wire power systems that require transfer between two power sources.

The listed internal configuration includes a 4-pole moulded-case circuit breaker, a dual-power transfer controller, three-phase voltage and current meters, a voltage change-over switch, copper busbars, dedicated wiring terminals, panel instruments, and indicator lights.

Supported configuration The cabinet is identified as model PA-ATS-4P and uses a fixed-board, all-packaged structure. Published electrical data includes AC 380/220 V at 50 Hz, 660 V rated insulation voltage, and a 0.8–0.95 lagging power-factor range.

Listed short-time withstand-current options are 16, 25, 31.5, and 50 kA. Overload and short-circuit protection are specified, while the also lists overvoltage, undervoltage, and phase-loss protection. Manual operation is supported, with electric operation offered as an option.

The enclosure is customizable and may be configured for floor or wall mounting. Published enclosure information includes a 1.5–2.0 mm cabinet-material thickness and selectable IP30–IP66 protection grades. The stated operating limits are -10°C to +40°C and an altitude of no more than 2,000 m.

Intended use The cabinet is presented for industrial facilities, factories, buildings, and new-energy installations.

The source description also identifies factory production lines, automation equipment, commercial buildings, data centers, communication base stations, hospitals, mines, oil fields, tunnels, and temporary construction sites as potential scenarios.

Suitability for any particular installation must be established through project-specific electrical and environmental review.

Buyer confirmation checklist Before procurement, confirm the required single-line diagram, actual load current, source arrangement, transfer sequence, fault-current level, neutral-switching requirement, and protection coordination.

Buyers should also verify the final enclosure dimensions, ingress-protection grade, mounting method, cabinet material and thickness, component brands, terminal layout, cable-entry direction, metering arrangement, and whether electric operation is required.

Request documented confirmation of the exact 315A configuration because the general published current-option list contains other ratings.

Confirm the applicable voltage and frequency, short-time withstand rating, transfer time, controller logic, interlocks, protective functions, and whether the installation requires uninterrupted or open-transition operation.

Certification applicability, inspection documents, wiring drawings, factory test records, installation requirements, spare parts, and warranty coverage should also be agreed for the ordered configuration.
