APDM Pole Mounted Fuse switch Disconnector For Line Protection
APDM fuse switch it is used either as an operation or protection device for LV line.It is designed to be used with NH 1-2 or 3 size fused offering a maximum of 630 Amps of line protection without blades.
In case blades are used ,the maximum switching load would be 800A. It is manu-factured in reinfored fiberglass polyamide and fulfills all the necessary requirements for outdoor installation and operation.
In the APDM model the connection is made with connectors suitable for aluminum and copper conductors with a section range between 16 and 95 mm2 (5-4/0 AWG).
The closure of the cap allows the switch to be closed with or without a fuse,prev-enting the risk of leaving tension parts exposed.It may also be provided with a light emission diode(LED).
Features
1. Designed for full load switching with fuse links of disconnector blades upto a rated current.
2. Mounting facility and unique modular design allowing one, two, three or more switches to be installed together to meet SP. TP or TPN system requirements.
3. Fully insulated made from corrosion proof, impact resistant, weather & UV resistant glass fiber reinforced polymide compound with high gladd content suitable for consistent performance under adverse climatic conditions.
4. The upper housing of the switch is hinged to the lower body and can be withdrawn by the insulated operation rod thereby enabling changing of fuse from ground level
5. Flexibility of linking a series of flaps for simultaneous operation.
6. The contacts, made up of ETP grade copper -duy plated are rigidly mounted in the housing independentof the terminal bolts. Single incoming & Double outgoing termination is provided in standard version.
7. Electrical & Mechanical fuse indicators are provided to show status of blown fuse.
