Product details

Its 24 VDC coil draws 5.4 W during both closing and holding, so the coil-supply circuit must be sized for continuous 5.4 W dissipation — no inrush spike to worry about, but the heat adds up in a dense panel. Rated 10 A in AC-12 duty (resistive loads at 24 V), it handles the control-circuit switching common in PLC output isolation and small heater banks.

The 65 mm width and 85 mm height leave room for auxiliary contact blocks alongside. Main and auxiliary/control circuits use screw-type terminals. Main terminals accept solid wire 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or max 2x (0.75–4 mm²); stranded accepts 2x (1–2.5 mm²), 2x (2.5–6 mm²), or max 2x 10 mm². AWG equivalents are 2x (16–12), 2x (14–10), 1x 8 for main contacts.

Type 1 coordination (contactor may need replacement after fault) allows a 100 A gL/gG fuse.

RoHS compliance date is 2006-07-01, meaning it meets the original EU RoHS directive. No REACH or UL listing is explicitly stated in the spec record, but as a Siemens industrial control product it typically carries CE marking and UL recognition — verify the specific UL file number against your panel's listing requirements.

Frequently asked questions

What are the key ratings for this contactor?

24 VDC coil drawing 5.4 W continuous. Rated 10 A AC-12 for resistive loads. For motor duty, AC-4 at 400 V is 15.5 A, and AC-2 at 400 V is 11 kW. Mechanical life is 10 million operations typical.

What wire sizes does the screw terminal accept?

Main contacts: solid 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max 2x (0.75–4 mm²); stranded 2x (1–2.5 mm²), 2x (2.5–6 mm²), max 2x 10 mm². AWG: 2x (16–12), 2x (14–10), 1x 8.

What short-circuit protection is required?

Type 2 coordination requires a 35 A gL/gG fuse. Type 1 coordination allows a 100 A gL/gG fuse.
