The S10 frame size measures 210 mm high, 145 mm wide, and 202 mm deep — a substantial footprint that needs a backplate or sub-panel with enough real estate. These aren't suggestions; they're the minimum air gaps to maintain arc flash and heat dissipation paths. Skimp on them and you risk tracking or nuisance tripping in a crowded enclosure. The main power circuit accepts stranded conductors from 70 up to 240 mm² — that's a heavy cable range, typical for motor feeders in the 50-100 A class. Spring-type terminals on the coil mean no screw torque to check; strip and push.
Duty-cycle performance
Switching frequency varies by duty class: 750 cycles/hour in AC-1 (resistive loads), 500 in AC-3 (standard motor starting), 250 in AC-2 (slip-ring motors), and 130 in AC-4 (plugging/inching). The AC-3e rating also sits at 500 cycles/hour. For a conveyor drive running continuous start/stop cycles, that 500 c/h ceiling is the real limiter — not the thermal current. Arcing time runs 10... 15 ms. The auxiliary contact ratings are 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V — these matter for your PLC input or relay interlock circuits.
No phase-out or last-time-buy notice is attached to this variant.
