Siemens 3RT20232AP00 S0 Contactor
This contactor's S0 form factor mounts on standard 35 mm DIN rail in conventional European industrial enclosures.
Engineering verification checklist
- Confirm system voltage matches coil rating (230VAC operational)
- Verify must-operate voltage (184 VAC) against available control supply
- Check 9A contact rating against load inrush and running current
- Validate auxiliary contact configuration (1NO/1NC) suits the control scheme
- Confirm operating temperature range (25°C ~ 60°C) is appropriate for installation environment
- Verify enclosure type matches application requirements (Box encapsulation)
- Check coil power consumption (65VA) against control transformer or supply capacity
- Confirm chassis/DIN rail mounting compatibility with panel layout
- Verify operate time (40 ms) meets timing requirements of the control circuit

3RT20232AP04 differs only in auxiliary contact count (2NO/2NC vs 1NO/1NC); shares the 230VAC coil voltage, 65VA power draw, and must-operate threshold of 184 VAC.
3RT20232AP60 uses a 240VAC coil with a proportional 192 VAC must-operate threshold and slightly higher 67VA inrush; otherwise identical 9A rating and DIN-mount form factor.
