It covers a motor power range of 1.1 to 6 kW depending on supply voltage: 1.1-2 kW at 200-240 V, 2.2-3 kW at 380-440 V, and 4-6 kW at 380-500 V. The thermal overload class is adjustable from Class 5 to Class 30, so you can match the trip curve to the motor's thermal time constant — Class 10 for standard motors, Class 20 for high-inertia loads, Class 30 for soft-start or long acceleration profiles. The front face carries a red push-button for stop and manual reset, a red knob for automatic reset, a white dial for full-load current adjustment, and two white microswitches for the adjustable trip class. This means you can set the overload threshold and reset behaviour without opening the panel — useful for commissioning or line-changeover adjustments.
Dielectric strength is tested at 6 kV at 50 Hz per IEC 60255-5 — that's the withstand between live parts and ground during type testing, not a continuous rating. The front face carries IP20 protection per IEC 60529 and VDE 0106, so fingers are protected but the interior is not sealed against moisture; mount it in an enclosure rated for the ambient conditions. The automatic reset time is fixed at 1.5 to 4 minutes — after a trip, the relay will cool and re-close the N/C contact within that window. If your safety circuit requires manual reset only, leave the red knob in the manual position. Operating altitude is 3000 m without derating — above that, air density drops and the thermal curve shifts; for installations above 3000 m, factor in a current derate per IEC 60947-4-1.
Mounts under a contactor via a plate, or on a rail with specific accessories. The dimensions are 3.1 in (79.9 mm) deep, 1.8 in (45 mm) wide, and 2.9 in (72.5 mm) tall — a compact footprint that fits standard DIN-rail enclosures. Tightening torque is 3.1 N·m for power and 0.8 N·m for control. The contactor coil is 24 V DC standard, drawing 300 mW — a low-power hold that can be driven by a PLC output or a small control transformer without derating the supply.
Certified to UL 60947-4-1, CSA C22.2, IEC 60947-4-1, and GB 14048.4 — covers North American and international motor starter standards. Protective treatment is TH per IEC 60068-2-30 (damp heat, cyclic). Electromagnetic compatibility includes surge withstand at 2 kV common mode (IEC 61000-4-5), electrostatic discharge at 8 kV (IEC 61000-4-2), radiated immunity at 10 V/m (IEC 61000-4-3), and fast transient immunity at 2 kV (IEC 61000-4-4). These are the standard industrial immunity levels for a motor starter in a panel.
