Siemens General Duty 400 Amp 240-Volt 3-Pole Indoor Fusible Safety Switch

General Duty Safety Switches are intended for applications where reliable performance and continuity of service are needed, but where duty requirements are not severe and usual service conditions prevail. These switches are intended for use primarily with supply circuits rated 240-Volt AC or less where the available fault current is less than 100,000 Amp when used with Class R or T fuses or 10,000 Amp max when used with Class H fuses.|3-Pole, 240-Volt, 400 Amp fusible safety switch|Quick-make, quick-break operating mechanism that ensures positive operation|Generous wiring gutters that meet or exceed NEC wire-bending space requirements|Visible blade, double-break switch action|Highly visible on/off indication|Single cover interlock|Side-hinged door that opens 180Ëš for easier wiring|Unique enclosure design that adds rigidity and strength, its rolled edge prevents cuts and scrapes to conductors and to installer's hands|NEMA type 1: enclosure is intended for indoor use primarily to provide protection against contact with the enclosed equipment in locations where unusual service conditions do not exist
