Description
HT (High Tension) panels are crucial components of electrical distribution systems in industrial and commercial setups. To enhance safety and prevent unauthorized or accidental access, door interlocks are integrated with the panel. These interlocks ensure that the panel’s door cannot be opened under unsafe conditions, reducing the risk of electrical hazards.

Dual Interlock System
Durable Construction
Working Principle
Normal Operation: The interlock system keeps the door securely locked when the panel is energized. Power Isolation: Once the power supply is turned off (using the main isolator or circuit breaker), the mechanical interlock is released, allowing safe access to the panel. Interlock Reset: The panel door must be closed properly and locked before power can be restored, ensuring no bypass of safety protocols.
Applications
Electrical distribution and substation systems.
Power generation plants.
Industrial automation and manufacturing plants.
High-voltage testing facilities.
