Installation of CORON® 2

The installation should be carried out by a qualified installer and in accordance with the regulations of the local distribution system operator.

The images below are for the 3 Pol. version (61-033); the installation for the 3 Pol.+N (61-034) is similar.

Step 1

Click onto the DIN rail, according to IEC/EN 60715.

Always mount CORON® 2 T horizontally. Pay attention to the rated diversity factor (RDF) according to IEC/EN 61439-1.

We recommend mounting a cassette with fuse plugs on the DIN rail next to the fuse(s) to make spare fuse plugs readily available. Replacing a blown fuse plug with a spare one avoids touching the hot fuse.CORON® 2 must always be mounted horizontally.

Step 2

Only use suitable wires:

  • Use only copper wires

  • Rigid, stranded, or flexible

  • Cross section 1.5 – 35 mm2

Strip the wires. Use ferrules for flexible wires.

Step 3

Always feed at the bottom of the fuse switch disconnector and load at the top. Secure with 3 Nm, using a PZ2 screwdriver.

Use the wiring diagram to connect the wires correctly. Refer to the tables below for the number of wires that can be connected.
