Product details

Motor switching and coil drive

The 3RT2026-2DB44-3MA0 is a SIRIUS 3RT power contactor rated for AC-3e/AC-3 duty at 25 A, switching 11 kW at 400 V on a three-phase motor load. The 24 V DC coil includes a plugged-in varistor for suppression, which saves you from having to add a separate snubber across the coil when the PLC or relay drives it. The auxiliary contact block is built in with 2 NO and 2 NC contacts, enough for a basic feedback loop to the controller and a status lamp without an add-on block.

Size S0 is the compact frame in the SIRIUS 3RT family — 54 mm wide, which fits a standard DIN-rail footprint. The captive auxiliary switch means the aux contacts are always present and cannot be lost during panel assembly. For a panel-builder, the spring-cage termination on a 25 A contactor saves time: no screwdriver torque check, and the wire retention is vibration-resistant.
