Product details

3 A adjustable time relay — what the ratings mean

The 3RA2815-1AW10 is a SIRIUS motor starter with an integrated adjustable time relay, rated for a maximum switching current of 3 A across AC/DC control voltages from 24 to 240 V. The adjustable time range spans 0.05 to 100 seconds, giving you a wide window for delayed start or sequenced motor engagement without an external timer module. The recovery time is 150 ms, meaning the relay resets quickly between cycles — relevant for rapid restart sequences in conveyor or pump applications where the motor must re-engage after a brief stop.

Mounting and panel fit — clip-on DIN rail, any orientation

Fastens via clip-on onto standard DIN rail, with a width of 45 mm, depth of 74 mm, and height of 38 mm. The mounting position is unrestricted — install it in any orientation, same as a contactor — which simplifies panel layout when space is tight. Clearance around the unit is zero in all directions (upwards, forwards, backwards, downwards, at the side), so it can be stacked directly against adjacent devices without derating for spacing.

Environmental limits — storage and operation

Rated for operation from -25 °C to +60 °C, with storage and transport tolerance from -40 °C to +85 °C. The basic insulation type covers standard industrial panel environments — no special derating needed for typical control cabinet conditions.

Frequently asked questions

What is the adjustable time range on the 3RA2815-1AW10?

The adjustable time range is 0.05 to 100 seconds, covering both ON-delay and OFF-delay configurations (though the unit itself is set for delayed switching with no separate ON/OFF delay selector).
