What it is

The DETA G3559 is a 20 A double pole switch engraved with the word BOILER. It is used to mark and isolate a boiler supply point, giving a clear permanent label at the point of control. The double pole (DP) configuration switches both poles of the circuit.

Before you order

  • Confirm a 20 A rating is suitable for the circuit being controlled.
  • Check that double pole isolation is required at the point of installation.
  • Verify the engraved legend BOILER matches the circuit it will label.
  • Cross-check the part number G3559 against the unit being replaced or the project specification.
