S0 frame contactor for motor switching
The 3RT2025-2AB04: It carries a 14 A rating at 480 V in AC-3 duty, which is the standard category for squirrel-cage motor starting and switching off during running.
Panel fit and clearances
Dimensions are 45 mm wide, 102 mm high, and 144 mm deep.
Duty-cycle limits and auxiliary contacts
Maximum switching frequency is 1,000 operating cycles per hour for AC-1, AC-2, AC-3, and AC-3e duty, dropping to 300 cycles per hour for AC-4 (plugging/inching). The contactor ships without an auxiliary switch block — if signal feedback is needed, a separate auxiliary contactor module must be added. Main contacts are 3-pole normally open (3 NO), rated for 18 A at AC-1 resistive load and 8 A at AC-3 motor load. The 14 A rating at 480 V AC-3 corresponds to approximately 3 hp at 230 V single-phase.
