Product details

Part identity and key ratings

The contactor is rated for motor switching: at AC-3 duty on 400 V it handles 7.5 kW, and at AC-4 on 400 V it carries 15.5 A. For resistive loads (AC-12) the maximum operating current is 10 A. At 690 V it is rated for 11 kW (AC-3). Mechanical endurance is listed at 10 million operating cycles, typical for this class of IEC contactor.

Main circuit terminals are screw-type, accepting solid or stranded conductors: 2x (0.25–2.5 mm²), 2x (1–2.5 mm²), 2x (2.5–6 mm²), or a single 10 mm². AWG equivalents are 2x (16–12), 2x (14–10), and 1x 8. Pollution degree 3 (industrial environment).

Protection and coordination

For Type 1 coordination (contactor may need replacement) the fuse can be up to 63 A gL/gG.

Frequently asked questions

What are the key electrical ratings for this contactor?

The coil is 230 V at 60 Hz. For motor loads: 7.5 kW at 400 V AC-3, 11 kW at 690 V AC-3, and 15.5 A at 400 V AC-4. For resistive loads: 10 A AC-12. The main contacts are 3 NO.

What is the mounting method and panel space needed?

Snap-on or screw mounting onto 35 mm DIN rail per EN 50022. Width is 65 mm, height 85 mm, depth 91 mm. Side-by-side mounting is allowed with 6 mm side clearance.

What wire sizes does the screw terminal accept?

Main circuit terminals accept solid/stranded: 2x (0.25–2.5 mm²), 2x (1–2.5 mm²), 2x (2.5–6 mm²), or max 1x 10 mm². AWG: 2x (16–12), 2x (14–10), 1x 8.

What short-circuit protection is required?

For Type 2 coordination (no damage) use a gL/gG 25 A fuse upstream. For Type 1 coordination (contactor may be damaged) use up to 63 A gL/gG.

What is the operating temperature and altitude range?

Operating temperature is -25 to +60 °C. Maximum altitude is 2000 m. Pollution degree 3.
