£61.85
The Mersen HR125 is a robust external front-operated pistol handle designed for use with compatible Mersen low-voltage disconnect switches. It provides a clear and dependable manual interface for operating an enclosure-mounted switch in industrial control panels, machinery and electrical distribution equipment.
Featuring a highly visible red finish and a practical 125 mm handle length, the HR125 is designed to support positive switch operation from the exterior of an electrical enclosure. Its pistol-style shape provides a secure grip, while its durable polyamide and stainless-steel construction supports reliable performance in demanding industrial environments.
The HR125 offers an IP65 and NEMA 3R rated installation when correctly fitted to a suitable enclosure and compatible switch arrangement. It is suitable for new panel-building projects, machinery installations and replacement applications where external front operation is required.
Enclosure-mounted disconnect switches provide a controlled means of isolating machinery and electrical equipment from the incoming power supply. An external operating handle allows the connected switch to be operated without opening the electrical enclosure, helping support safer and more convenient isolation procedures.
The Mersen HR125 is designed to connect to a compatible disconnect switch through the appropriate operating shaft and mounting arrangement. Its pistol-style form, environmental protection and durable construction make it suitable for industrial panels where reliable external switching is required.
