Submersible 4 Way Switchgear Products

Innovative Switchgear’s solid-dielectric-in-air submersible switches and fault interrupters are similar in size and shape to existing oil-filled and SF6-filled units and thus easily utilizes existing vault and manhole spaces. One advantage of the compact size is that utility companies can now add fault interrupting capabilities where they previously had switching capabilities. Our switchgear is available in 12.5kA, 16kA and 20kA, and is suitable for 4kV – 27kV applications. All products feature our visible open isolation point which is visible from a safe working distance away from the switchgear. Our units are operated by a single handle which will de-energize, isolate and create the visible open. Each unit is constructed of 304 stainless steel, and is sealed dead-front. All products are submersible, i.e., fully-sealed, and not subject to moisture intrusion. Our equipment performs and thrives, even when submerged in 10 feet of water. It is the ideal solution for underground and coastal applications where flooding may occur.

Load-Break Switch Applications:

Innovative Switchgear provides vacuum fault interrupter contacts in every load-break switch it manufactures. By featuring fault interrupter contacts (in lieu of load-break contacts) in all switch applications, Innovative Switchgear offers a remarkable added measure of safety, reliability and operational duty over conventional load-break switches. In addition, Innovative Switchgear’s internal switch mechanism is dual certified to both IEEE C37.74 2003/2014 (switch standard) and IEEE C37.60 2012 (fault interrupter standard) which means that our switches are the safest, most durable, and most reliable in the marketplace today.

Fault Interrupter Applications:

Innovative Switchgear’s fault interrupters meet the IEEE C37.60 2012 standard, and include internally mounted current transformers and substation quality microprocessor relays. These products provide 3-phase 600 amp load current interruption, as well as 12.5 kA, 16 kA and 20 kA fault interruption. Our fault interrupters feature both Schneider Electric and Schweitzer Engineering Labs (SEL) relays as our standard protection devices.

Innovative Switchgear’s equipment features:
