UL 98 Non-Fused Load Break Switches Mersen disconnect switches are extremely durable, manually operated, non-fused disconnect switches. These heavy-duty switches are designed with the most up-todate disconnect switch technology available. Designed to suit the UL98 or UL489 standard, the switch gives you a product that makes and breaks power circuits on load. The switches are tested and approved for use in demanding applications, such as Service Entrance. Up to 400A, the switches are available with visible blade contacts. A wide array of handles are available to meet OSHA padlocking requirements, NEMA configurations, defeater options and NFPA 79 requirements. Features/Benefits UL 98 Service entrance rated Front or side operated switches Padlockable Compact Robust DIN-rail, panel or door mounting Lockable, defeatable external handles Side-mounted auxiliary contacts and additional poles available The SXDC switches are rated 600VDC UL and 000VDC IEC Highlights: Visible blade contacts up to 400 A Line side shrouding supplied with switch Defeatable pistol handles automatically re-latch when panel door is closed - no tool necessary to reset latch External or direct operation handles Flange operation (for use with side operated switches) Double-break, silver-plated contacts SX series has flexible terminal shields that allow for tighter wire bending Applications: Service entrance or main panel disconnects up to 600VAC, 00A Make and break power circuit applications on load NFPA 79 solutions Photovoltaic Ratings: Volts : 600VAC / DC : UL and 000VDC IEC Amps : 30A, 60A, 00A, 00A, 400A, 600A, 800A, 000A and 00A SCCR : Up to 00kA with fuses Suitable as motor disconnect up to 00hp Approvals: All switches meet the requirements of UL and CSA UL listed guide WHTY, File E9605 for UL 98 (ratings from 30 A to 00 A) CSA. # 4, class 465-04, File 70366 (ratings from 30 A to 00 A) IEC 947-3 CE mark (other IEC ratings up to 5,000A available on request, please consult us) 5
