The S0 frame size keeps the width at 45 mm, depth at 107 mm, and height at 102 mm — a compact footprint for panel density. Coil termination uses spring-type terminals, accepting solid or stranded wire from 1 to 10 mm² (or 2x 0.5 to 2.5 mm²). The rated control supply voltage spans 21 to 28 V, with an inrush current peak of 3 A. At 24 V rated value, the contactor draws 10 A; at 48 V and 60 V, 2 A each; at 110 V, 1 A. These figures govern the control transformer sizing and fuse selection for the coil circuit. Mechanical life is typical 10,000,000 operations.
Switching duty and operating rates
Maximum operating frequency at AC-1, AC-2, AC-3, and AC-3e duty is 1,000 cycles per hour; at AC-4 duty it drops to 300 cycles per hour. Switching times (closing + opening) are 30 to 50 ms for AC and 30 to 50 ms for DC.
Clearance and integration
Minimum clearance distances for the S0 frame: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side. These spacings must be maintained to adjacent components or enclosure walls for proper heat dissipation and arc containment. The contactor's power factor at 50 Hz is 0.86; at 60 Hz, 0.82 — relevant for reactive load calculations.
