Can the Acti 9 incomer switch SEA9NI1603 have a Undervolt or Shunt 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 Undervolt trip unit, Shunt trip unit, or Auxiliaries fitted. This is because they are based on the Interpact INS range.

The only Acti9 switch incomer that can have a Undervolt or Shunt or auxilliary fitted is the SEA9NI2254 as this is based on the NSX range
