Medium Voltage Load Break / Load Interruptor Switches - Model HPL-C
ITE / BBC / ABB

ITE, in the 1950’s developed a line of load interrupter switches designated
HPL-C. for the length of its design well into the late 20th century, it was characterized by stored energy closing mechanisms with mechanical and electrical operators.

The assemblies were available in voltages ranging from 5000 volts through 15000 volts. Interrupting current availability of the switches ranged from 600 to 1200 amp.

Momentary ratings were available as high as 61,000 amps.

The HPL-C models of switches have been obsoleted by the original manufacturers.

All HPL-C load interrupter switches and switch enclosures are available from Satin International and Satin American.

ITE also developed a line of High Voltage Fuses to be used in conjunction with its load break switches.

All replacement parts are available for all switch assemblies. These include:

  - Main Stationary and Movable Contact Assemblies,
  - Arcing Stationary and Movable Contact assemblies,
  - Whipper blades,
  - Archutes, Pushrods,
  - Electrical operators, Manual Operators,
  - High Voltage Fuses, Fuse Holders
  - Key Interlock assemblies
