It mounts directly onto a contactor (contactor mounting per), saving DIN-rail space in the panel.
The relay comes with screw-type terminals for both the main current circuit and the auxiliary/control circuit. The terminal blocks accept solid conductors: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²) per, with the same range for finely stranded wire with core-end processing per. AWG equivalents are 2x (20... 16) and 2x (18... 14) for the main circuit, plus 2x (20... 16) and 2x (18... 14) for the auxiliary contacts per and. No separate accessory pack is needed for basic wiring — the terminals are integral.
Clearances and mounting position
Physical envelope: 87 mm high, 45 mm wide, 78 mm deep. Required clearances to adjacent components: 0 mm upwards, 0 mm forwards, 0 mm backwards, 0 mm downwards, and 6 mm at the side. The mounting position is flexible — the relay can be mounted on a vertical surface with ±135° rotation and ±45° tilt to the front and back. That covers most panel layouts without derating.
Environmental and electrical ratings
Relative humidity during operation can reach 100 %. Shock resistance is rated at 8g for 10 ms. Power loss per pole is 1.6 W. Rated operational currents vary by voltage: 1 A at 24 V, 0.22 A at 110 V, 3 A at 120 V, 0.22 A at 125 V, 0.11 A at 220 V, 2 A at 230 V, and 1 A at 400 V.
