Product details

The 24 VDC coil draws 5.4 W during both closing and holding, so the power supply sizing is straightforward — no inrush spike to over-spec for. For resistive loads (AC-12), the maximum operating current is 10 A.

Wiring and coordination specifics

Screw terminals on the main circuit accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid wire — or 2x (1 to 2.5 mm²) and up to 2x 10 mm² stranded. AWG equivalents are 2x (16 to 12) and 2x (14 to 10) for the smaller range, with a single 8 AWG maximum. This covers most panel wiring up to about 4 kW motor circuits directly. The 6 mm side clearance is the minimum for side-by-side mounting without derating. Maximum altitude is 2 000 m.

The reference code Q per DIN EN 81346-2 indicates it is intended as a power switching device in the functional schematic — useful for documentation traceability when matching nameplates to panel drawings.
