Product details

Its coil accepts 24–60 VAC at 50 or 60 Hz, drawing 8.5 VA at either frequency, so it fits standard control transformers without oversizing. The contactor carries two normally-open and two normally-closed instantaneous auxiliary contacts, rated for switching up to 4 A at 230 V, 3 A at 400 V, and 2 A at 690 V — covering most pilot-duty and small-load applications in a 400/690 V panel.

Mounts via screw fixing on a vertical surface; the enclosure can be rotated ±180° or tilted forward/backward ±30° at 0° rotation, giving flexibility in tight cabinets. Dimensions are 225 mm high, 184 mm wide, 180 mm deep — a substantial footprint that fits standard S12 panel cutouts.

Wiring and auxiliary contacts

The auxiliary switch block is present and can accept up to two additional attachable contact blocks for expanding signal feedback. Pickup voltage threshold is 0.8 x rated (about 19.2 VAC minimum), dropout at 1.1 x rated (about 26.4 VAC maximum) — ensures reliable pull-in and avoids chatter on a sagging control bus.

Frequently asked questions

What are the key ratings for the auxiliary contacts?

The two NO and two NC instantaneous contacts are rated 4 A at 230 V AC, 3 A at 400 V, 2 A at 690 V, and also carry ratings at 24 V (3 A), 48 V (1.5 A), 110/125 V (0.55 A), 220 V (0.3 A), and 500 V (2 A). These cover pilot-duty and small-load switching across common control voltages.

What is the coil voltage and frequency range?

The coil is rated for 24–60 VAC at both 50 Hz and 60 Hz, drawing 8.5 VA at either frequency. The pickup threshold is 0.8 x rated (minimum ~19.2 VAC), and dropout is 1.1 x rated (maximum ~26.4 VAC).

What are the physical dimensions and mounting requirements?

Height 225 mm, width 184 mm, depth 180 mm. Mounts via screw fixing on a vertical surface with ±180° rotation and ±30° tilt. Required clearances: 10 mm up, 10 mm down, 20 mm forward, 10 mm side.

What conductor sizes does the screw terminal accept?

The screw-type coil terminals accept 1x or 2x conductors from 1 to 4 mm², solid or stranded — no special ferrules needed for standard panel wiring.
