Product details

The front panel carries IP20 protection — safe for finger contact inside an enclosure — while the terminal area is IP00, meaning the live parts need enclosure protection.

Screw terminals accept a wide wire range: solid conductors from 2x 0.5 to 4 mm², stranded from 2x 0.75 to 25 mm². For the main circuit, the maximum solid or stranded is 2x 16 mm². At 40 °C the minimum permissible conductor size is 16 mm² — relevant when sizing for continuous full-load current. The coil draws 10 A at 24 V rated value, dropping to 0.3 A at 220 V rated value.

Frequently asked questions

What are the key motor ratings for this contactor?

AC-3 motor-switching rating is 30 kW at 500 V and 11.4 kW at 690 V. For reversing or plugging duty (AC-4), it's rated 41 A at 400 V. Maximum operating rate at AC-3 is 800 switching cycles per hour.

What wire sizes does the screw terminal accept?

Solid conductors: 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², max 2x 0.75 to 4 mm². Stranded: 2x 0.75 to 25 mm². Main circuit max solid or stranded is 2x 16 mm².

Does this contactor mount on standard DIN rail?

Yes, it mounts on 35 mm DIN rail per EN 50022, either by screw fixing or snap-on. Side-by-side mounting is allowed.

What compliance documentation is available for this part?

The part carries a substance prohibitance date of 05/01/2012, indicating RoHS compliance. As a Siemens SIRIUS catalog item, it is CE-marked and designed to relevant IEC/EN standards for contactors.
