Product details

Clip-on auxiliary switch with ON-delay

The 3RT1926-2EC11: It adds a timed normally-open contact that closes after a set delay, without needing a separate timer module. The delay is adjustable from 0.05 to 1 s, with a recovery time of 150 ms between cycles. The coil draws from the contactor's own control voltage — 100 to 127 V AC at 50 or 60 Hz — so it shares the same supply without an extra transformer.

Contact ratings and wiring

The switch contact is rated 3 A maximum, with specific ratings of 1 A at 24 V, 0.2 A at 125 V, and 0.1 A at 250 V. These are the resistive load limits; the 24 V figure is the one most often checked for PLC input or relay coil switching. The clip-on fastening method means it snaps onto the contactor without tools — no DIN-rail space consumed.

Frequently asked questions

What is the time delay range of 3RT1926-2EC11?

The ON-delay is adjustable from 0.05 to 1 s. Recovery time between cycles is 150 ms.

Is 3RT1926-2EC11 compatible with Siemens 3RT1 contactors?

Yes, the 3RT1926-2EC11 is designed as a clip-on auxiliary switch for the SIRIUS contactor family, which includes the 3RT1 series. It mounts directly on the contactor front without tools.
