Why Choose the Mersen HB80 External Operating Handle?
The Mersen HB80 is a durable external front-operating pistol handle designed for compatible Mersen low-voltage disconnect switches. Its black industrial construction and 80 mm handle length provide a secure and accessible means of operating a disconnect switch installed inside an electrical enclosure.
Designed for use with compatible 200 A and 250 A non-fusible disconnect switches, the HB80 enables operators to isolate electrical equipment without opening the enclosure door. This supports safer switching, servicing and maintenance procedures while reducing direct access to internal electrical components.
The Mersen HB80 is manufactured from robust PA66/6 engineering polymer with stainless steel components. When correctly fitted to compatible equipment, it provides IP65 protection and supports NEMA Type 1, 3R and 12 enclosure applications, making it suitable for demanding industrial control and power distribution installations.
