3RT1934-5AC21
The 3RT1934-5AC21 is a 24V AC control coil for a Siemens SIRIUS S2 size contactor with a rated frequency of 50/60Hz. It has been verified that it is compatible with the 3RT1033-1AC20 and 3RT1034-1AC20 contactors. It can be directly inserted into the original coil socket for replacement and is a commonly used maintenance part on the production line.
Product Positioning
The 3RT1934-5AC21 is a 24V AC coil used with Siemens SIRIUS S2 size contactors. Verification confirms its compatibility with contactor models 3RT1033-1AC20 and 3RT1034-1AC20. This coil can be directly replaced from the panel without removing the entire contactor, making it a practical spare for quickly troubleshooting coil failures on production lines.
Core Product Advantages and Features
Confirm Applicable Model
It has been verified that it is directly applicable to 3RT1033-1AC20 and 3RT1034-1AC20 contactors. However, it is still recommended to check the model number on the nameplate before selecting it.
AC24V low voltage specification
The rated voltage is AC 24V, which meets the low voltage circuit design requirements of most PLC control panels.
50/60Hz Dual-Band Universal
The same coil can be used for both 50Hz and 60Hz power frequencies, eliminating the need for separate material preparation.
Corresponding to S2 size contactor
This is a standard coil specification belonging to the Siemens SIRIUS S2 size large contactor series.
Replacement without disassembly
The coil can be replaced directly when the contactor is mounted on the panel, reducing maintenance time.
Original factory authorized source
Kenxin Motors is an authorized distributor of Siemens, providing genuine original parts and a full warranty.
