XINTAIHELE 3P 100A 220V Mini ATS Automatic/Manual Transfer Switch — DIN-rail, Flame-Retardant

The XINTAIHELE 3P 100A 220V Mini ATS is a compact dual-mode transfer switch that automatically or manually transfers three-phase power between mains and backup sources to keep circuits energized.

This compact Automatic Transfer Switch (ATS) is built for installations that require reliable switching between primary and secondary power sources. Designed for 220VAC systems, the unit supports both automatic transfer when outages occur and manual operation for maintenance or testing. Its DIN-rail form factor and flame-retardant materials make it suitable for distribution boxes in commercial and light-industrial settings.

How does this ATS detect and switch power sources?

The XINTAIHELE ATS monitors incoming voltages and engages the backup source when the main supply drops below safe thresholds. When the mains voltage returns and stabilizes above the required level, the device transfers power back automatically. Manual override lets an operator take control for planned work or diagnostics.

• Automatic sensing of mains vs backup voltage to trigger switching
• Manual transfer mode for technician-controlled changeover
• Designed for 220VAC 50/60Hz systems with a working range above 190V

What electrical specifications and protections should I know?

This model is rated for three-phase (3P) operation at 100A continuous current and is intended for 220VAC environments. Contact materials are industrial-grade silver for better conductivity and contact life. The enclosure materials are flame-retardant and heat resistant, improving safety in confined electrical cabinets.

• Rated operating voltage: 220VAC, 50/60Hz (do not operate below 190V)
• 100A rated current suitable for small distribution circuits
• Silver alloy contacts for improved conductivity and wear resistance

How easy is it to install and integrate into existing panels?

The slim DIN-rail design lets installers mount the ATS quickly inside standard distribution boxes and control cabinets. Terminal layout is arranged for straightforward wiring of mains, backup, and load connections. Its compact footprint makes it a good fit for urban lighting controllers, small commercial panels, or equipment rooms where space is limited.

• DIN-rail enclosure for fast mounting in standard distribution boxes
• Compact footprint designed for constrained panel space
• Clear terminal access for mains, generator/backup, and load wiring

What operational environments and use-cases suit this switch?

The XINTAIHELE mini ATS was developed for applications that need dependable source transfer without a large controller footprint. Typical installations include municipal lighting, retail centers, airport subsystems, small industrial loads, and backup circuits for critical low-to-medium power equipment. It performs best where the mains voltage remains within the recommended operating range.

• Urban and street lighting control panels
• Malls, airports, and commercial distribution cabinets
• Backup power transfer for small industrial and critical loads

Who is this for: Electrical contractors, facility managers, and installers who need a compact, robust transfer switch for 220VAC three-phase circuits will find the XINTAIHELE 3P 100A Mini ATS useful. It suits projects requiring automatic failover with the option for manual control, especially where panel space is limited and materials with higher temperature and flame resistance are preferred. Ensure your site voltage stays within the expected range (above 190V) for reliable operation.
