Product details

The kit is complete: the contactor body ships with the terminal hardware for the main and auxiliary circuits — no separate accessory pack needed for a standard install.

Dimensions are 71 mm wide, 85 mm tall, and 101 mm deep — the S0 frame fits standard 35 mm DIN rail enclosures.

Each NO and NC auxiliary contact is rated 20 A continuous. The main circuit handles impulse withstand at 6 kV. Switching frequencies reach 1 000 cycles per hour at AC-1 maximum. For DC switching at 24 V, the maximum permissible current is 0.016 A — this is a signal-level rating, not for power DC loads. The contactor is built for AC motor and resistive loads; the DC curve drops sharply as voltage rises.

Frequently asked questions

What are the key dimensions for panel layout?

Width 71 mm, height 85 mm, depth 101 mm. Side-by-side mounting requires a 6 mm air gap at the side. Mounts on 35 mm DIN rail per EN 50022.

What is the coil voltage and contact configuration?

24 VDC coil. Three instantaneous NO main contacts. Auxiliary contacts rated 20 A per NC and per NO contact.

What is the operating temperature range?

During operation -25 to +60 °C. Storage -55 to +80 °C. Maximum altitude 2 000 m.
