It is built on the Size S00 contactor frame, which means it shares the 45 mm width and screw/snap-on mounting footprint with the S00 power contactor family.
The 4 NO contacts are all instantaneous (no leading, lagging, delayed, or make-before-break variants), so this is a straight parallel set for standard control logic. Switching capacity is given per contact at several voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — these are the thermal current ratings at those AC voltages, so the contactor can handle the listed current at the stated voltage in a control circuit. The 6 kV rated surge voltage resistance means the contacts can withstand transient spikes common in industrial panels without welding or arcing over. If your PLC output card drives this contactor at 24 V and 10 mA, you are well above that threshold, so no dry-contact issues. The mechanical life is 30 million operating cycles typical.
Fastening is by screw or snap-on mounting onto a DIN rail. This matters when you are squeezing it into a tight gland-plate layout or a rotating sub-panel. Wire cross-sections accepted: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), and 2x 4 mm² solid. That covers most control-circuit wiring from 20 AWG to 12 AWG. The 72 mm depth and 57.5 mm height are standard for the S00 frame, so it will fit existing S00 backplates and gland plates without interference.
For BOM freeze or compliance documentation: the substance prohibitance date is 07/01/2006, which aligns with RoHS compliance. Shock resistance is 10g / 5 ms and 5g / 10 ms, which covers most industrial vibration environments.
