Application
The fuse switch disconnectors are used for closing on and disconnection of rated
operating currents up to 160 A AC.
Installation
For dimension drawings, Fig. Ia
see
Maintain clearances to earthed components!
For permissible mounting positions, see Fig. Ib
For rear mounting, see Fig. IIa, b
For installation apertures and mounting holes, see
Fit contact carrier with 2 M5 (not hexagonal-head) screws. Always use plain and
spring washers.
Fit insulating-material block 3NY72.., see
Connection cover 3NY7101 for cable lug connection, see Fig. III.
If necessary, can be locked into position on the device at both connection sides by
pressing into guide slot.
Unlock by pressing on cover

Fig. VII for fitting of the fuse links or disconnecting links
See
Use fuse links with silver-plated blades or silver-plated disconnecting links only!
Where fuse monitoring is concerned, use only fuse links with live grip links!
Fig. IIe
See for fuse carrier installation.
Voltage test
(in the case of devices without fuse monitoring)
Use voltage test probes with diameter of ≤ 2,4 mm and minimum length of 38 mm.
The voltage is picked up at the fuse blades.

Maintenance
Grease the main contacts according to switching rate (with Shell Alvania RLQ2 or
another high-grade aging-resistant mineral-oil-based lithium-soap grease/worked
penetration: 265 - 295, service temperature: -30 to +120 °C).
