Rated for 30 kW at 500 V and 11.4 kW at 690 V, with an AC-2 rating of 22 kW at 400 V — that's the duty cycle for slip-ring motor starting or moderate overloads. The AC-3 maximum switching rate is 800 cycles per hour, which covers most conveyor and pump starts without derating.
At 55 mm wide, 112 mm high, and 115 mm deep, the S2 frame leaves room for adjacent devices on the rail. The front face carries an IP20 rating; the terminals themselves are IP00, meaning the wiring compartment is open but the operator touch points are protected. That covers control wiring through to motor power leads in a single terminal block — no need for adapters or reducers on the line side.
