Rated for AC-2 duty at 15 kW and AC-4 reversing duty at 29 A, both at 400 V, this contactor handles slip-ring motor starting and reversing applications where frequent jogging or inching is required. The terminals themselves are IP00 — no touch protection at the wiring point, so panel builders should plan for terminal shrouds or additional guarding.
RoHS compliance date is noted as May 1, 2012, and the part carries a substance prohibitance declaration for REACH compliance.
At 55 mm wide and 130 mm deep, the S2 frame occupies one standard DIN-rail module position. Side-by-side mounting is permitted — no derating required for adjacent contactors at rated current. The coil terminals accept 2x 0.5–1.5 mm² solid or 2x 0.75–2.5 mm² stranded. Strip length for screw terminals follows standard practice — 10–12 mm for the larger conductors.
Coil and switching characteristics
The 110 V DC coil draws 10 A at 24 V inrush and 1 A at 110 V holding. Dropout time is 20–30 ms, arcing time 10–15 ms — fast enough for most safety circuits but verify coordination with upstream overcurrent devices. Electrical life depends on duty: 1,200 ops/hour at AC-1, 1,000 at AC-3, 750 at AC-2, and 250 at AC-4 — the reversing duty class limits switching frequency to about 4 operations per minute.
