Request Information

MD2SR Factory Sealed Interlocked Switched Receptacles are designed to provide short circuit protection in 30, 60 and 100 Amp versions. The internal, factory sealed switch provides safe and reliable power for hazardous, damp and corrosive environments. They are typically used for applications that require portable or fixed heavy duty equipment. A special polarization option prevents the insertion of a plug into a receptacle or connector that is wired for a different voltage.
Features
  • Class J fused version: short circuit withstand rated to 200,000 RMS symmetrical amperes.

  • Unfused version: short circuit withstand rated to 10,000 RMS symmetrical amperes.

  • Positive polarization; only plugs of the same style, number of poles, and Amperage rating may be used with these receptacles.

  • Plug must be inserted into the receptacle before the switch can be turned on. Plug cannot be withdrawn unless the switch is in the off position.

  • Insulated, dual-color polymer operating handle clearly indicates the switch being energized. Ergonomically designed handle is made of high-impact polymer material for exceptional ruggedness, durability and corrosion resistance.
