It is designed to switch control and signal circuits in motor control centers and distribution panels, typically driven by a larger power contactor or PLC output to extend the number of auxiliary contacts available for status feedback, interlocks, or logic wiring. The S00 footprint keeps it compact at 45 mm wide, 60 mm tall, and 73 mm deep — a common size that slots into existing panel layouts without re-spacing.
The 4 NO contacts are rated for 10 A at 24 V, dropping to 6 A at 230 V and 3 A at 400 V. This means the contactor handles higher currents at lower control voltages, typical for pilot-duty signaling, and derates predictably as line voltage rises. The 6 kV rated surge voltage resistance indicates the contacts can withstand transient overvoltages common in industrial environments without welding or arcing over. Contact reliability is specified as one incorrect switching operation per 100 million cycles at 17 V, 1 mA — a dry-circuit rating that matters when switching low-energy signals like PLC inputs or sensor feedback. If the signal level is that low, the contacts will hold a clean circuit without needing gold plating or sealed relays. Pollution degree 3 confirms it tolerates conductive pollution typical of control rooms and light industrial floors.
The auxiliary switch extension is supported, meaning you can add more contact blocks on top of the base 4 NO configuration without replacing the contactor. This is useful when a panel revision adds feedback points after the initial build.
Integration notes
Wire capacity is 2x (0.25 to 2.5 mm²) solid or stranded — standard for control wiring. Terminals accept ferruled conductors; strip length is typical for screw-clamp terminals. Shock resistance is rated at 10g for 5 ms and 5g for 10 ms, which is sufficient for mounting on a panel door or inside a cabinet near vibrating machinery like pumps or conveyors. The contactor will not drop out or chatter under normal industrial vibration.
