Can the Acti 9 incomer switch SEA9NI1603 or SEA9PNI1603 have a Undervoltage release or Shunt trip coil fitted?
No the SEA9NI1603 CANNOT have a Undervolt or Shunt fitted.

With one exception none of the Switched disconnectors for the B Type boards can have Undervoltage release coil, Shunt trip coil, or Auxiliaries fitted. This is because they are based on the Interpact INS range.

The only Acti 9 switch incomer that can have a Under voltage release or Shunt trip coil fitted is the SEA9NI2254 as this is based on the NSX range
