PT 4-EX(I)-BE - Surge protection base-element

Base element for protective plug PT with protective circuit for a 4-core floating EEx ia signal circuit. Nominal voltage: 24 V DC, for mounting on NS 35/7.5 and NS 35/15, housing width: 17.5 mm

  • Maximum ease of maintenance, thanks to the 2-piece design
  • Easy selection for all possible demands in MCR applications with a complete product portfolio
  • The signal is not influenced during maintenance work, thanks to the impedance-neutral insertion and removal of protective plugs
