It is designed to protect motors against overload by monitoring current and tripping within CLASS 10 time limits. The relay carries ATEX certification (DMT 98 ATEX G 001), so it is approved for use in potentially explosive atmospheres per the ATEX directive — a critical check for oil and gas, chemical, or grain-handling installations where a standard thermal overload would not be permitted. The front face is IP20 rated, meaning finger-safe against accidental contact, but the relay itself is not sealed against moisture or dust ingress — it is intended for installation inside an enclosure rated to the environment.
Mounts directly onto a contactor via the fastening method specified as contactor mounting — no separate DIN-rail clip required. The mounting position allows a vertical mounting surface with ±135° rotation, or ±45° tilt to the front and back, giving flexibility in tight panel layouts. This means it can be stacked directly against adjacent devices on three sides, saving DIN-rail space in densely packed panels. Physical dimensions: 55 mm wide, 105 mm tall, 118 mm deep. The 118 mm depth is the full projection from the mounting surface — verify cabinet depth clearance before specifying, especially in shallow enclosures.
Main current circuit terminals accept stranded conductors from 0.75 mm² up to 35 mm², or two conductors per terminal (0.75 to 25 mm²). Auxiliary and control circuit terminals accept solid conductors 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²), and finely stranded with core-end processing the same range. AWG equivalents for auxiliary contacts: 2× (20 to 16) and 2× (18 to 14). Power dissipation per pole is 5.2 W at rated current — total 15.6 W for the three poles. This matters for thermal management inside sealed enclosures; factor it into the cabinet's heat budget.
Relative humidity during operation can reach 100 %, so the relay tolerates condensing environments inside the enclosure. Shock resistance rated at 8g for 10 ms. Surge voltage resistance rated at 6 kV. Substance prohibitance date per RoHS is July 1, 2006 — the part is RoHS-compliant. Auxiliary contact ratings: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, 0.22 A at 110 V, 0.22 A at 125 V, 0.11 A at 220 V. These are the switching capacities for the integrated auxiliary contacts — match your control voltage to the appropriate column.
