Medium Voltage Load Break Interrupter Switch for Soft Starter Panels | 5kV–38kV, 600A/1200A
Indoor medium voltage load break interrupter switch for soft starter panels, MCCs and transformer feeders. Available in 5kV–38kV, 600A/1200A, manual or motorized, with fuse and grounding options. Ideal for MV motor starter OEM and retrofit projects.
Our medium voltage load break interrupter switch is designed for indoor metal-enclosed medium voltage equipment, especially for medium voltage soft starter panels, motor control centers (MCC), transformer feeder cubicles, and combination motor starters.
Available in 5kV to 38kV classes, with 600A and 1200A options, this 3-pole group-operated air-insulated load break switch features a stored energy quick-make / quick-break mechanism, making it ideal for demanding industrial motor control applications.
It is widely suitable for projects requiring a medium voltage soft starter disconnect switch, a fusible load break switch, or a replacement for legacy North American PIF-style load break interrupter switches commonly seen in Benshaw, TEAMmaster, MVC4, and other UL / NEMA style MV starter lineups.
• Designed for MV soft starters, MCCs, and motor control lineups
• 5kV / 7.2kV / 15kV / 27kV / 38kV voltage classes
• 600A / 1200A continuous current ratings
• Manual (MO) or Electrical Operation (EO) available
• Supports switch-fuse and fuse-switch configurations
• Optional grounding bar / earthing function / interlocks
• Ideal for OEM integration, retrofit, and replacement projects
In medium voltage motor control systems, the load break interrupter switch remains a critical safety and isolation component. Even in advanced solid-state soft starter systems, the upstream switching section still requires a reliable load break / fault make disconnect switch for maintenance isolation, fuse coordination, and visible safety verification.
Our frame-mounted indoor medium voltage load break interrupter switch is engineered for this exact application.
It is a 3-pole, single-throw, group-operated switch with a stored-energy spring mechanism that delivers quick-make / quick-break performance independent of handle speed, helping ensure safe operation and reliable load interruption in industrial environments.
