Features

  • Surge module easily snaps into place
  • Mechanical flag will protrude to indicate the module needs to be replaced
  • Thermal disconnect releases the indicator when the device reaches end-of-life, disconnecting itself from the circuit to prevent it from becoming a short or shunt
  • Surge module attaches to the base with a latching mechanism that easily locks the device into place, preventing the module from disconnecting during service
  • Integration of GDT (gas discharge tube) technology and MOV (metal oxide varistors), a combination that delivers consistency and the capability to protect against fast spikes
  • Screw-less cage clamp terminal allows for easy connection, solid or stranded wires are simply pushed in to lock into place, reducing installation time by as much as 75%
  • DIN rail grounding connection eliminates the need for extra grounding wires
