Technical Parameters Parameter Specification Notes / Explanation Series / Type System Pro M - GS Switch-Disconnector with Fuse Bases Device Type 3-Pole Load Break Switch-Disconnector with Fuse Bases Standard Compliance IEC/EN 60947-3, IEC/EN 60947-1 Poles 3 Poles (Main Circuit) + Fuse Poles Main Circuit Ratings • Rated Operational Voltage (Ue) 690 V AC • Rated Insulation Voltage (Ui) 800 V AC • Rated Operational Current (Ie) 32 A (AC-23A) Switch mechanism rating. Fuse Specification (F) Key Feature • Fuse Type D-type (Cylindrical) Fuses per IEC 60269, e.g., 10x38mm or 14x51mm sizes. This is indicated by the F in the model code (vs. NH for knife-blade fuses). • Fuse Rating Range Typically accepts fuses from 0.5A to 32A (gG/gL) or up to 63A (aM). Actual max depends on the specific fuse base version. • Short-Circuit Performance Rated Conditional Short-Circuit Current (Icq) is typically 50 kA when used with specified D-type fuses. Handle (C16) • Type Front-mounted, rotary handle with a large black knob. Mounts directly on the front of the switch body. • Function Manual operation, clear ON/OFF indication. Can be padlocked in the OFF position (usually 1-2 padlocks). Utilization Category AC-23A (For switching of squirrel-cage motors) 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 Auxiliary Contacts Optional add-on auxiliary contact blocks (e.g., GS-AX series) for signaling. Not included in base F C16 version. Terminals Screw-clamp terminals. Connection Capacity Up to 16 mm² (for main terminals) Mounting Mounts on 35 mm DIN Rail (EN 60715). Protection Degree IP40 (with handle installed) Ambient Temperature Operating: -25°C to +70°C Pollution Degree PD 3 Dimensions (W x H x D) Approx. 72 mm x 122 mm x 115 mm (for 3-pole switch-fuse) Weight Approx. 0.6 kg (without fuses) Safety Approvals CE, cULus, CCC, etc.
