Approvals & Standards

  • All UL Fusible Disconnect Switches meet UL & CSA requirements
  • UL listed guide WHTY, File E191605 for UL 98 (ratings from 30A to 1200A)
  • IEC 60947-3

Key features & benefits

Mersen’s fusible disconnect switches are listed to UL 98 and bear the CE mark conforming to IEC 60947-3. They are “service entrance” devices capable of fully rated load-break and load-make. While longterm safety, reliability, and functionality are always paramount in the design of our products, these switches are also engineered to have the smallest footprint. The modular design allows placement of the handle anywhere amongst the poles. The fuse doors cannot open when the switch is in the “ON” position, and all switches are double-break, which isolates both fuse clips from voltage during fuse replacement. The switches’ “Test” position allows actuation of the auxiliary contacts without main power. Power taps enable energizing a CPT or surge device without the need for a separate terminal block. A wide range of ergonomic handles and accessories is available.
