Automatic Transfer Switch for Generator 10-63A PC Class ATS

Name: Automatic Transfer Switch for Generator - ETEK Electri
SKU: EKATS5

The EKATS5 is a compact automatic transfer switch for generator and mains backup systems. Rated 10–63A at AC 50/60Hz, it moves the load to standby power in about 20 ms, and returns to mains automatically once normal supply is restored.

Product Features of Automatic Transfer Switch for Generator

The EKATS5 automatic transfer switch for generator is a PC class, two-station change-over switch built to IEC 60947-6-1.

Fast electromagnetic drive: A fast-acting electromagnet drives the switching. The default control voltage is AC220V, and AC110V can be customised.
Self-switching and self-restoring: In automatic mode, power I (main supply) has priority when both supplies are present.
Built-in power sampling: There is no separate control power line. You only connect the switch to the main circuit.
Clear status indication: Indicators show common (main), backup, and load power. Optional passive auxiliary contacts (version “F”) signal normal/backup status. Mechanical position indicators and manual/automatic selectors are fitted for both sources.
Modular, compact design: Same-side incoming lines make wiring easier. The unit weighs about 0.5 kg.
Arc extinguishing system: The arc is split into series arcs in the grid, then stretched, cooled, and extinguished by electromagnetic force.
Robust construction: The shell is fire-resistant. The PCB has a three-proof (conformal) coating for harsh environments.

Commercial Applications of Automatic Transfer Switch for Generator

The EKATS5 automatic transfer switch for generator suits AC 50/60Hz systems up to 63A where the load must keep running when the main supply fails. In practice it sits between the utility mains (source A) and a standby generator (source B).

Applications & Use Cases

(The datasheet has no application list. These are inferred from the product’s function, so please review them.)

Small commercial and retail premises with a standby generator.
Offices, server and network cabinets, and telecom equipment.
Security, lighting, and fire-safety circuits.
Light industrial control panels and distribution cabinets.
Mains-to-backup changeover in cabinets, installed vertically or horizontally.
