  • IM – switch unit
  • IMC – unit with current measuring
  • IMB – Switch unit with earthing disconnector, right or left outgoing line
  • IMM – switch and measurement unit, right or left outgoing line
  • NSM – power supply for main incoming line on right or left and cables for standby line (Automatic Transfer System)
  • QM – Fuse-switch combination unit
  • QMC – Fuse-switch combination unit
  • QMB – Fuse-switch combination unit right or left outgoing line

Switch mechanism:

  • CI1 operating mechanism
    • Disconnector manipulation

Independent-operation opening and closing by lever or motor

Independent-operation opening by push-button (O) or trip units.

  • Earthing switch manipulation

Independent-operation opening and closing by lever

  • Motor option – Standard or severe environment and communication
  • Closing – release shunt trip

A mechanical interlocking of the disconnector and earthing switch was performed on the mechanism in order to prevent incorrect manipulation.

  • DM1-A – Single-isolation, disconnectable circuit breaker unit
  • DM1-D – Single-isolation, disconnectable circuit breaker unit right or left outgoing line
  • DM1-M – Single-isolation,disconnectable circuit breaker and measurement unit right outgoing line
  • DM1-S – Single-isolation, disconnectable circuit breaker unit with autonomous protection
  • DM2– Double-isolation, disconnectable circuit breaker unit right or left outgoing line

Switch mechanism:

  • CS operating mechanism
    • Disconnector manipulation

Independent-operation opening and closing by lever.

  • Earthing switch manipulation

Independent-operation opening and closing by lever

A mechanical interlocking of the disconnector and earthing switch was performed on the mechanism in order to prevent incorrect manipulation.

Switch mechanism:

  • RI operating mechanism
    • Switch function

Independent-operation closing in two steps:

First operating mechanism recharge by motor or lever, then release of the stored energy by push-button (I) or trip unit.

Independent-operation opening by push-button (O) or trip units.

  • Opening releases – Mitop (low energy), shunt trip
  • Closing release – shunt trip
  • Motor option – Standard or severe environment and communication

A key-type interlock (type 50) is fitted on the units as standard to prevent the wrong sequence of manipulations between the switch and the disconnector (the disconnector does not switch off under load).

  • DM1-W – Single-isolation, disconnectable circuit breaker unit
  • DM1-Z – Withdrawable single-isolation circuit breaker unit right outgoing line

NOTE: The circuit breaker is pulled out of the cell (there is no option to pull the switch from inside the cell). This allows quick circuit breaker replacement.
