Why Choose the Mersen HR65 External Disconnect Switch Handle?

The Mersen HR65 is a compact and durable external pistol-style operating handle designed for use with compatible Mersen low-voltage disconnect switches. Its highly visible red finish and 65 mm length provide a clear manual interface for electrical isolation in industrial machinery, control panels and power distribution equipment.

Designed for external front operation, the HR65 allows a compatible disconnect switch to be operated while the electrical enclosure remains closed. The handle connects to the switch through the appropriate operating shaft and mounting arrangement, supporting convenient and controlled switching from outside the panel.

When correctly installed as part of a suitable enclosure assembly, the HR65 provides an IP65 environmental protection rating and supports NEMA 1, 3R and 12 enclosure applications. Its compact size makes it particularly suitable for installations where panel space is limited but dependable external switch operation is required.

Key Advantages

  • External front operation allows switching without opening the electrical enclosure.
  • Compact 65 mm pistol-style handle for space-conscious panel designs.
  • Highly visible red finish clearly identifies the isolation control.

Reliable External Operation of Disconnect Switches

Disconnect switches provide a controlled means of isolating machinery and electrical equipment from an incoming power supply. An external operating handle enables the connected switch to be moved between its operating positions while the enclosure remains closed.

The compact design of the Mersen HR65 makes it suitable for smaller industrial panels and machinery enclosures. When correctly matched with the required disconnect switch, shaft and mounting components, it provides dependable manual control for electrical isolation applications.

Typical Applications

  • Industrial machinery isolation.
  • Electrical control panels.
