Arc resistant switchgear channels the energy released during an internal arc fault in ways that minimize the potential for injury to personnel and damage to surrounding equipment. Across the line, this switchgear leads the way in arc resistant technology. It’s available in ANSI Type 1 or Type 2 construction with no larger footprint than the standard switchgear design. Circuit breakers are interlocked so they cannot be opened, closed or racked to the connected position with the arc resistant door open. This minimizes the opportunity for operator error. But arc resistant protection is important at every step, not just when opening and closing the circuit breaker, so our single-latch doors close and engage in a single action, which provides virtually automatic protection for the operator. The pressure release venting panels are maintenance-free.

Intuitive interface makes operation simple. Little or no learning curve required to operate system.
A main screen with navigation buttons and non-system critical button/switches.
System testing screen allowing the operator to manually initiate automatic system testing operations.
Generator interface settings latched into the PLC control system upon entry.
System load add/shed manual control redundant to hard-wired manual control switches in master control.
Generator optimization settings latched into PLC control system upon entry.
The system is designed to dynamically add or shed load based on the system load level rather than using inflexible load blocks.
The system is programmed to dynamically track the size of each load individually. This allows the system to quickly determine exactly how many loads are to be added to or shed from the system, whether it is in the middle of the afternoon or in the middle of the night.
A GE governor controller is supplied which has the functionality required by different applications and the flexibility to communicate with all types of existing engines. (Can be used in conjunction with speed controller or can do it itself.)
Capable of soft loading and unloading the generator.
Var/pf controller built in, load sharing (kW and kVar).
Equipped with its own automatic synchronizer that checks for voltage matching.
