Ratings that decide fit
The contactor carries 2 normally-closed instantaneous auxiliary contacts. At 24 V they're rated 10 A, at 230 V they're rated 6 A, and at 400 V they're rated 3 A. That covers most control-voltage ranges you'll see in a panel — 24 VDC control circuits, 230 VAC pilot duty, or 400 VAC interlocking. Coil consumption is 5.4 W for both closing and holding on DC. That's a continuous-duty coil — no pulse-width economizer needed, but it does mean the coil stays warm. The operating temperature range is -25 to +60 °C, and the maximum operating altitude is 2 000 m. Pollution degree 3 means it's rated for industrial environments with conductive dust or condensation — typical for an unsealed panel. The front face carries IP20 finger protection; the terminals themselves are IP00, so they're live when the panel door is open. That's standard for this class — the panel enclosure provides the overall ingress protection.
Lifecycle and sourcing reality
The reference code per DIN EN 81346-2 is Q, which designates it as a switching device in the functional schematic. That's a documentation detail for panel builders who tag their drawings to the standard.
Coordination and protection
For Type 2 coordination (no damage to the contactor after a short circuit), the required upstream fuse is gL/gG 35 A. For Type 1 coordination (contactor may need replacement after a fault), the fuse can be gL/gG 100 A. That's the spec the panel designer needs to match to the branch circuit protection. Mechanical life is 10 million operations typical. That's a long service life for a contactor in a cycling application — well above the electrical life under full load, which will be lower and depends on the switching category.
