The Din Type TP Fuse Switches are used for distribution boards and feeder pillar boxes. These switches guarantee operating safety against accidental contact and has adequate breaking capacity.These Din Type TP Fuse Switches are known for their compact design & easy mounting. It is economical to use vertical type fuse switches in the LV Distribution boards. Further, the dimensions are reduced by using these fuse switches and the total cost of the switchgear is thus essentially cutdown.
Characteristics:
- The fuse switch can be closed on the short circuit fault without danger to the operator.
- It utilizes AC22 as per IEC 408 category. The Body is made of high quality glass fibre-reinforced polyster (DMC) which is mechanically strong, heat resistant & self extinguishing type.
- The contacts are of copper silver plated, spring assisted provided with arc of chutes with adequate number of splitter plates for quenching the arc.
- The connections are made of electrolytic copper tin plated which is brought to one level at the bottom for cable termination with phase L1 on the left hand side. The hinged front cover is available with painted steel.
- Protection against accidental contact with live parts even if the switch cover is open. HRC Fuse Switches generally meet the requirement of IEC 408.
Installation:
- Fuse Switches can be installed in the LV Distribution board at a center to center assembly.
- The distance should be of 100 mm and a depth of 135 mm.
- These can be directly bolted on the bus bars spacing 185 mm as per DIN 43623 Form B.
- Easy cable termination is possible at the bottom of the fuse switches without any strain on the terminals.
