Product details

74x45x38 mm DIN-rail clip-on — panel fill factor

The 3RA2813-2AW10: The 74 mm depth, 45 mm width, and 38 mm height footprint clips onto standard DIN rail — no screws, no bracket. Mounting position is any orientation, same as a contactor, which simplifies layout in a crowded panel. Wire range accepts 20-14 AWG solid or stranded, so it ties into existing control wiring without a terminal adapter.

ON-delay only — adjustable 0.05-100 s, universal control supply

This is a single-function ON-delay timer relay — no OFF-delay, no pulse-shaping, no star-delta timing. The delay is adjustable from 0.05 to 100 seconds via a front-panel potentiometer (or screwdriver slot), so you dial in the interval on-site without swapping modules. Control supply voltage is AC/DC 24-240 V at 50/60 Hz — one part covers both line and low-voltage DC control schemes, reducing panel stock complexity. Recovery time is 150 ms — the minimum off-time before the timer can retrigger. If the application cycles faster than that, the output may not reset.

Industrial temperature range and pollution tolerance

Rated for operation from -25 to +60 °C, with storage and transport limits of -40 to +85 °C — fits unconditioned cabinets and outdoor-adjacent enclosures. Basic insulation with pollution degree 3 means it's designed for industrial environments where conductive dust or condensation may be present — no need for a sealed enclosure in a typical panel.

Frequently asked questions

What is the 3RA2813-2AW10's adjustable time range?

The ON-delay is adjustable from 0.05 to 100 seconds, set via the front-panel adjuster. This covers most sequence-start and anti-short-cycle timing needs in motor control panels.

What control voltage does the 3RA2813-2AW10 accept?

It accepts AC or DC from 24 to 240 V, at 50 or 60 Hz. One part works across 24 V DC PLC outputs, 120 V AC control transformers, and 240 V AC line supplies.
