Product details

Specification Summary for Procurement

The main circuit uses screw-type terminals, accepting conductors from 2x (0.5... 1.5 mm²) up to a maximum of 2x (0.75... 4 mm²) or 1x 12 AWG. The front and terminal faces are rated IP20 for finger-safe installation within an enclosure.

Switching Performance and Application

For motor switching duty, the contactor is rated at 4 kW at 400 V in AC-2 duty (slip-ring motor starting) and 8.5 A at 400 V in AC-4 duty (plugging/inching of squirrel-cage motors). At 690 V, the motor power rating is 5.5 kW; at 500 V, it is 4.5 kW. These ratings define the maximum motor load the contactor can switch under those specific duty cycles. The auxiliary contact block provides switching capability at multiple voltage levels: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V.

Environmental and Installation Conditions

Physical dimensions are 45 mm width, 57.5 mm height, and 72 mm depth, fitting the standard S00 footprint for panel layout planning.
