The SIRIUS 3RT1026-3XG28-0MV0-ZW98 is a Size S0 power contactor rated for AC-3 duty at 25 A, switching 11 kW at 400 V. The 110 V AC coil operates on 50/60 Hz. This is a phased-out product — the official successor is the SIRIUS 3RT2 series. The AC-3 rating of 25 A and 11 kW at 400 V defines its motor-switching capability for standard squirrel-cage induction motors. That 11 kW figure is the load it handles under typical starting and running conditions, not a resistive-heater rating. The contactor ships with a pre-attached RC suppression module on the coil. Auxiliary contacts are configured as 1 NO + 1 NC standard plus an additional 1 NO + 1 NC set that is solid-state compatible, meaning those two contacts are designed to switch lower-current PLC or drive inputs without the usual contact wetting issues.

Frequently asked questions
What replaces the 3RT1026-3XG28-0MV0-ZW98?
The manufacturer's stated successor is the SIRIUS 3RT2 series. A direct form-fit-function check against the specific 3RT2 order code is needed before substitution, as terminal style, coil voltage, and auxiliary contact configuration may differ.
What are the key ratings for this contactor?
AC-3 rated at 25 A and 11 kW at 400 V. The coil is 110 V AC, 50/60 Hz. It has 3 main poles and auxiliary contacts configured as 1 NO + 1 NC standard plus 1 NO + 1 NC solid-state compatible. Terminals are spring-type. Size S0, 45 mm wide.
How does this compare to the 3RT1015-1BB42?
The 3RT1015-1BB42 is a Size S00 contactor (45 mm wide but shallower at 72 mm depth vs S0's larger frame) with a 24 V DC coil and screw terminals. The 3RT1026-3XG28-0MV0-ZW98 is Size S0 with a 110 V AC coil and spring terminals. They are not direct drop-in replacements — the mounting footprint and coil voltage differ.
