ENERGON Intelligent Low Voltage Switchgear FAQ

What is ARC SAFE arc-resistant technology? What are its advantages?

ARC SAFE is NATUS Electric's patented fully enclosed vertical busbar system with an automatic safety shutter. When a drawer is withdrawn, the shutter automatically closes to shield the busbar and maintain IP4X protection, eliminating electric shock risk during energized maintenance. The all-round insulation design also prevents arcs between contact chambers and limits fault expansion.

Can ENERGON Intelligent Draw-out Low-Voltage Switchgear System really be maintained while energized? Is it safe?

Yes. ENERGON supports energized replacement of functional units. DTS transmission enables door-closed operation with unchanged protection level throughout the process; the mechanical code lock prevents wrong insertion; and the ARC SAFE busbar shields energized parts, ensuring safe energized maintenance through multiple protections.

What is the difference between a PD cabinet and an MD cabinet? Where are they used?

A PD cabinet is the main incoming/outgoing cabinet used to install high-current frame circuit breakers (630A-6300A), suitable for system main incoming, busbar section and high-current outgoing. MD cabinet is a multifunction MCC cabinet used to install various small-capacity withdrawable / plug-in functional units, suitable for motor control and multi-circuit feeders.

What Makes ENERGON an Intelligent Low Voltage Switchgear System?

ENERGON can integrate intelligent meters, power quality modules and communication interfaces to support remote monitoring, fault diagnosis and power distribution management. Available protocols and functions depend on the selected configuration and project requirements.
