SAJ ATS1-S63-A (single-phase automatic transfer switch, 63 A)
SAJ ATS1-S63-A is the single-phase automatic transfer switch: 63 A, 50 ms changeover between grid supply and inverter backup.
- 50 ms changeover, which is inside the window a fridge, a router and a heating pump ride through without restarting.
- Three independent 63 A ports — grid in, inverter in, backup load out — so the backup circuit is separated in the switch rather than improvised in the consumer unit.
- IP54 and -25 to +50 °C up to 3000 m, overvoltage category III, protection class I, to IEC/EN 61439.
- Listed by SAJ against the H1, H2 and HS2 single-phase inverter families, and takes either a meter module or an eManager as the metering accessory.

ATS1-S63-A, specified from the datasheet.
Every value on this page is transcribed from the manufacturer documentation on file.
50 ms, three ports
Grid, inverter and backup load each get their own 63 A port, and the changeover is 50 ms — inside what a fridge or a heating pump rides through.
Inspect it before you spec it.

Configuration 2
Phases, and nothing else that matters.
- ATS1-S63-A (this one): single-phase — the ordinary German residential connection.
- ATS1-T63-A: three-phase.
- Identical otherwise: SAJ's datasheet gives both the same 520 x 518 x 142 mm enclosure, the same 15.8 kg, the same 63 A, the same IP54 and the same 50 ms changeover.
SAJ lists it against its single-phase storage families. The datasheet names the H1 and H2 S2 series, the H2 S3 series and the HS2 line. If your inverter is a three-phase unit, you want the T63 instead.
Put your inverter model on the enquiry and we will confirm the pairing against SAJ's configuration instructions before the quote goes out.
Operation & warranty 1
It is the gap between the grid dropping and the inverter carrying the backup circuit.
- Rides through: fridges, freezers, routers, heating circulation pumps, lighting.
- Does not ride through: anything needing a true no-break supply — a desktop without a UPS may still restart.
- Not a UPS: this is a transfer switch. It selects a source; it does not hold the load up during the transfer.
Installation & wiring 1
A wall-mounted IP54 enclosure, 520 x 518 x 142 mm and 15.8 kg.
- Temperature: -25 to +50 °C.
- Altitude: up to 3000 m.
- Electrical class: overvoltage category III, protection class I, to IEC/EN 61439.
- Metering: takes a meter module or an eManager.
Availability & compliance 1
Half-pallet freight at 15.8 kg net, no dangerous-goods handling.
- Warranty: two years, SAJ's own figure for this unit.
- Documentation: the ATS1 datasheet we hold is SAJ's Spanish edition, which is the edition that carries both the single-phase and three-phase columns. The specification values on this page are translated from it; the source document is linked so you can check any row.
- Lead time: confirmed after order.
