What it is

The Stag IS4P100 is a 100A, 4-pole rotary isolator switch in an enclosed, IP65-rated housing, built from flame-retardant material to IEC 60947 and UKCA/CE approved. The rotary handle is lockable and the isolator only opens in the OFF position, giving safe load-break isolation of a circuit.

Signs this part needs replacing

  • Rotary handle feels loose, stiff, or fails to lock in the OFF position
  • Enclosure lid or seal is cracked, letting in moisture or dust
  • Visible arcing, scorch marks or a burning smell around the terminals
  • Switch no longer fully isolates the circuit when turned to OFF

Before you order

  • Match the existing isolator's current rating, pole count and enclosure dimensions before ordering a replacement
  • Isolate and lock off the supply before removing the old switch
  • Have the work carried out or verified by a competent, qualified electrician
