Technical Parameters Parameter Specification Notes / Explanation Series / Type System Pro M - GSJ High Breaking Capacity Switch-Disconnector Device Type Manual Rotary Switch-Disconnector (Isolator) Provides visible isolation gap. Standards IEC/EN 60947-3, IEC/EN 60947-1 Poles 3 Poles (Standard for this frame). Also available in 2-pole and 4-pole versions with different codes. Main Circuit Ratings • Rated Operational Voltage (Ue) 690 V AC • Rated Insulation Voltage (Ui) 800 V AC • Rated Impulse Withstand Voltage (Uimp) 8 kV • Rated Operational Current (Ie) 32 A (at AC-23A) The 201 in GSJ201 typically indicates the 32A frame size. Breaking Capacity Key differentiator of the GSJ series. • Rated Service Short-Circuit Breaking Capacity (Ics) 25 kA at 415V AC, cos φ=0.25 Can interrupt a 25kA fault and remain operational. • Rated Ultimate Short-Circuit Breaking Capacity (Icu) 36 kA at 415V AC, cos φ=0.25 Maximum fault current it can safely interrupt. • Rated Making Capacity (Icm) 66 kA (peak) at 415V AC For closing against short-circuit. Utilization Category AC-23A (For switching of squirrel-cage motors, up to 8xIe inrush) Also suitable for AC-20, AC-21, AC-22. Mechanical Life ≥ 20,000 operations Electrical Life (AC-23A) ≥ 5,000 operations at full rated current Handle (C32) Key Feature • Type Flush-mounted, square-shaped rotary handle. Provides a flat, professional panel appearance. • Knob Black rotary knob, can be padlocked in the OFF position (typically up to 3 padlocks). • Mounting Installed through a 30x30 mm square cutout in the panel door. • Position Indicator Clear ON (I) / OFF (O) marking on the knob. Auxiliary Contacts Optional add-on auxiliary contact blocks (e.g., GS-AX series) for signaling ON/OFF status. Not included in base C32 version. Terminals Screw-clamp terminals suitable for copper/aluminum cables. Connection Capacity Up to 35 mm² (for main terminals) Mounting Mounts on 35 mm DIN Rail (EN 60715) or directly on a panel. The switch body is mounted inside the cabinet.
