It is part of the broad SIRIUS family, which covers most industrial contactor applications from simple on/off to high-cycling duty.
The S0 footprint is 45 mm wide, 102 mm tall, and 97 mm deep — a standard size that fits most distribution boards and motor control centers without crowding adjacent devices.
The AC-3 and AC-3e maximum switching frequency is 1,000 operations per hour, which covers most standard motor start/stop cycles on pumps, fans, and conveyors. For high-duty applications like reversing or inching (AC-4), the rate drops to 300 operations per hour — a real constraint if you are designing a jogging station. The auxiliary contact ratings cover a range of control voltages: 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, and 0.3 A at 220 V. This covers most PLC output cards and relay interfaces without needing an interposing relay.
