SGU-Series 208V-480V UL Listed ANSI C37.20.1 Low Voltage Switchgear
208V, 480V, 600V - Low Voltage Paralleling, Transfer, & Distribution Fully Assembled Electrical Switchgear Up to 4000A Main Bus
Designed to Meet UL 891 Requirements
This complete line of 208V – 690V indoor and outdoor switchgear is the ultimate in flexibility and has options available to meet virtually any power system needs.
- Standard bus ampacity up to 4000A
- Busbar connections with NEMA standard hole
pattern - Bus Access & Cable Entry
– Front or Rear Access for either top or bottom
cable entry - Insulated Case Circuit Breakers
- Molded Case Circuit Breakers
- Intelligent close prevents simultaneous connection
of multiple generators to dead bus
Automatic Transfer Transition Options
- Automatic standby with Open Transition
return operation:
– Time delayed control sensor detects if a utility outage has occurred
– When timer expires, the generator set is automatically started and brought up to speed and voltage
– Utility circuit breaker opens and
generator circuit breaker closes (after adjustable time delay) so that generator supplies power to the site load
Low Voltage Switchgear Options
Some of the available options include:
- Automatic Load Transfer Switching operation
- Automatic Main-Tie Main operation
- Configurations with multiple Main and multiple Tie circuit breakers
- Incorporation of any size dry type transformers
- Automatic paralleling of multiple generators for Prime Power application
- Automatic paralleling of multiple generators for Co-Generation application
- Automatic paralleling of multiple generators for Peak-Shaving application
- Automatic paralleling of dissimilar prime movers such as: gas turbines, diesel engines, natural gas reciprocating engines, landfill and digester gas reciprocating engines, combustion turbines, synchronous and induction generators, inverter based systems, motor-generators, wind and solar driven generators
- Seamless load transfer between power sources
- Solid, low impedance and high impedance grounded systems
- Indoor (Nema 1), Outdoor non walk-in (Nema 3R) and Outdoor walk-in (pre-engineered heated and air conditioned equipment enclosure) configurations
- Heavy skid mounted switchgear and substations
- Provisions for maintenance grounding of the feeder cables
- Web enabled, remote monitoring and control
- Remote control and relay panels
- Remote access switchgear control line-ups for ultimate operator safety
