Frequently asked questions
Will this contactor drop into a panel designed for the 3RT2036-1AK64?
Mechanically yes—same frame size and DIN-rail mounting. But the coil terminal type (screw-type on this variant) may differ from the base version, and this variant has no built-in auxiliary contacts. Verify coil voltage and auxiliary requirements against your panel design.
The 3RT2036-1AK64-3MA0: Ambient operating range is -25 to +60 °C, and the unit mounts on 35 mm DIN rail (screw and snap-on per DIN EN 60715) with the mounting position allowing ±180° rotation on vertical surfaces.
How this variant differs from the base 3RT2036-1AK64
Compared with the base 3RT2036-1AK64 (no suffix), the -3MA0 variant uses screw-type magnet coil terminals rather than push-in or cage-clamp connections. That changes the wiring method but not the panel footprint—both are size S2 with the same 55 mm width, 114 mm height, and 174 mm depth. The base 3RT2036-1AK64 often ships with a standard coil voltage; the -3MA0 variant is sourced specifically with the coil voltage and special markings that match your order. Verify coil voltage from the full order code before substituting.
