Terminal Connection

Applications and Industries where it is used

Electrical Panel Manufacturing

  • Where: Mounted on control panels, distribution boards, and starter panels.
  • Why: To measure and monitor the real-time current flowing through circuits.

Building Management Systems (BMS)

  • Where: Used in main panels, subpanels, HVAC, lighting, and tenant metering units within a BMS.

  • Why: help monitor current flow, detect faults, and optimize energy usage across building systems.

Generator / DG Set Panels

  • Where: Installed on the generator control panel to display the phase-wise output current.

  • Why: To monitor output current and ensure the generator operates within safe load limits.

Commercial Sub-Metering / Retail Malls

  • Where: Installed inside individual distribution boards or sub-panels allocated to each shop or tenant.

  • Why: to measure individual tenant or shop-wise energy consumption for accurate billing and energy management.
