3RT20244AN60 — Same S0 series, matching 67 VA inrush coil power and 3PST-NO main contacts. The 220 VAC coil shifts the must-operate threshold to 187 VAC versus 192 VAC for the seed.
3RT20244AG60 — Same base part number and auxiliary-contact feature set. The 110 VAC coil reduces must-operate voltage to 93.5 VAC, maintaining identical switching times and mounting.
3RT20244AK60 — Matches the seed on contact configuration and 12 A rating. The 120 VAC coil operates at 96 VAC must-pickup, closest to the seed's 192 VAC threshold among the three.
Overview
The Siemens 3RT20244AP60 is a Size S0 electromechanical contactor in the 3RT2024 series, rated 12 A per pole at the stated coil voltage. It carries a box encapsulation and ships with one normally open and one normally closed auxiliary contact, enabling feedback or interlock paths without additional modules. The 240 VAC coil draws 67 VA during energization.

Integration Notes
The contactor mounts directly to chassis or a 35 mm DIN rail, accommodating standard panel-builder practices for motor-branch or lighting-contactor applications. The auxiliary-contact complement (1 NO + 1 NC) supports control-circuit interlock or status-feedback wiring without adding separate relay modules. Coil voltage selection must align with the upstream control-circuit nominal voltage; the must-operate threshold of 192 VAC establishes the minimum pickup point for the 240 VAC designation. Operating-time specification of 40 ms applies to pull-in; release time is not listed in this record.
FAQ
