Opus - Operator Protection Upgradeable Safety


LV incoming disconnectors, switch disconnectors


The Merlin Gerin range of disconnectors provide operator protection to IPXXB in all operating conditions.
Assembled from single units as either a TP or TP&N horizontal or vertical arrangement the compact and flexible design has enhanced ratings and can accommodate an integral CT for transformer load monitoring.

Incoming disconnector
  • Off-load disconnector used to provide a visible point of isolation from the incoming transformer supply.
  • Operator protection from live conductors to IPXXB in closed, open and transitional positions.
  • Special insulated tool to operate the disconnector.
  • Disconnector and insulated handle fully interlocked to ensure that the disconnector cannot be left in a transient position.
  • Optional integral current transformers for monitoring transformer load.
  • Vertical and horizontal configurations available as either three pole or three pole and neutral assemblies
  • Neutral link is rated at 50% that of the phase rating as standard, full size neutrals available upon request.
Incoming switch disconnector
  • On load switch that can be used in conjunction with generator backup for a ‘no break’ changeover to generator and vice-versa.
  • Certified manually dependent switching capability.
  • Operator protection from live conductors to IPXXB in ‘on’, ‘off’ and transitional positions
  • Special insulated tool to operate the switch disconnector.
  • Switch disconnector and insulated handle fully interlocked to ensure that the switch disconnector cannot be left in a transient position.
  • Optional integral current transformers for monitoring transformer load.
  • Vertical and horizontal configurations available as either three pole or three pole and neutral assemblies.
  • Neutral link is rated at 50% that of the phase rating as standard, full size neutrals available upon request.
