Why Choose the Mersen HB65 External Operating Handle?
The Mersen HB65 is a compact and durable external front-operation pistol handle designed for compatible Mersen low-voltage disconnect switches. With a 65 mm handle length and an ergonomic industrial design, it provides a secure manual interface for operating a disconnect switch mounted inside an electrical enclosure.
The HB65 allows the connected switch to be operated externally without opening the enclosure door. This supports safer circuit isolation during normal operation, servicing and maintenance while helping reduce operator exposure to internal electrical equipment.
Manufactured from durable PA66/6 engineering polymer with stainless steel components, the Mersen HB65 features a black finish and provides IP65 and NEMA Type 1, 3R and 12 protection when correctly installed with compatible equipment. It is suitable for industrial control panels, machinery and power distribution applications operating at voltages up to 600 V AC.
