Siemens 3RT20241AP60 S0 Contactor
The 3RT20241AP60 is a DIN-rail or chassis-mountable electromechanical contactor in the Siemens S0 frame, suited for line-voltage switching of three-phase loads in industrial control panels and motor-branch circuits.
Coil inrush power is specified at 68 VA; the main poles present a 3PST-NO (three Form A) arrangement with a rated current of 12 A and one each normally-open and normally-closed auxiliary contact.
Engineering verification checklist
- Confirm system nominal voltage matches coil rating of 240 VAC before energizing the coil circuit.
- Verify load current does not exceed the 12 A contact rating at the applied voltage in the intended duty cycle.
- Check that the must-operate voltage (192 VAC) is met under minimum expected supply conditions.
- Confirm DIN rail or chassis mounting provisions are compatible with the enclosure layout.
- Validate that auxiliary contact functions (1NO/1NC) match the control circuit interlock or signaling requirements.
- Confirm operating ambient temperature range (25°C to 60°C) is appropriate for the installation environment.
- Verify coil power draw (68 VA inrush) is accommodated by the associated control transformer or supply.
- Ensure operate time of 38 ms is acceptable for the specific timing requirements of the circuit.

3RT20241AP00: Same S0 frame and 12 A rating; differs only in coil voltage (230 vs 240 VAC) and slightly lower inrush power (65 VA). Shares the same auxiliary contact configuration and chassis/DIN mounting.
3RT20241AK60: Matches on frame size, current rating, and auxiliary contact arrangement; uses a 120 VAC coil instead. Must-operate voltage scales proportionally (96 VAC) and inrush power is identical at 68 VA.
3RT20241AV60: Same S0 contactor with 12 A main poles and 1NO/1NC auxiliaries; coil rated for 480 VAC with a corresponding higher must-operate threshold of 408 VAC and increased inrush at 73 VA.
