Key features of our LS1 Single Side Break Switch
Made with a hot‑dip galvanized steel base featuring field‑adjustable mounting provisions, ensuring strong structural support and installation flexibility.
Equipped with maintenance‑free dry‑lubricant bearings and non‑magnetic hardware in all live parts, supporting smooth and dependable operation over time.
High-conductivity copper blades and terminal pads with silver-plated hard drawn copper contacts. Contact pressure is maintained by a stainless-steel coil spring.
The rotating insulator bearing is a key part of a side break disconnect switch. The best current-carrying design is useless if not mated to a high strength and reliable bearing like the EMSPEC design.
Fully ice tested.
