It carries four normally-open main contacts and zero normally-closed — so it's a straight make-only device, typically wired to close on a start command and drop on a stop or fault. The coil pulls 5.4 W DC both on closing and holding — a constant-hold design, so no power drop after pickup.
Screw-type terminals on the main circuit accept 2x (1 to 2.5 mm²) solid or 2x (2.5 to 6 mm²) stranded, with a maximum of 2x 10 mm². The coil terminals take 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) with ferrule. Strip length for the main terminals: 12 mm for the larger cross-sections. Pollution degree 3.
