  • Deliver equipped or in flat kits
  • Assembled by panel builder
  • Ratings up to 4000A
Motor Control

Motor Control

NEMA motor control with high-interrupting capacity used to protect wound-rotor and synchronous motors.

  • Used to feed transformers and other power-utilization circuits
  • Available in various types of ratings, sizes, enclosures and arc-resistant models
Air Insulated Switchgear

Air Insulated (SecoGear)

Designed with safety in mind, SecoGear meets IEC and GB standards and has metal clad primary compartments equipped with pressure relief flaps to guide gasses to the topside if an internal arc occurs.

  • Busbar fully insulated with inter unit bushing prevents internal arc travel between sections
  • Embedded poles in the VCB require no maintenance
Gas Insulated Switchgear

Gas Insulated (RMU)

Ring power supplies improve system reliability. The ring main unit (RMU) serves the secondary distribution level up to 36 kV and is maintenance free.

  • Rated for indoor or outdoor; modular and extendable
  • Combines gas insulated technology and MV metal enclosed technology
  • Embedded pole circuit breaker, disconnect switch and busbar sealed in stainless steel gas tank filled with insulated gas
  • Compact, modular, high-performance and maintenance-free switchgear

Medium-Voltage Innovation

Advanced Arc Protection & Maintenance-Free Operation

Our SecoGear air-insulated switchgear features pressure relief flaps and fully insulated busbars to contain internal arcs. For demanding environments, gas-insulated RMUs provide sealed, maintenance-free operation up to 36 kV.

  • Internal arc pressure relief system
  • Embedded VCB poles - no maintenance required
  • Modular, extendable RMU for indoor/outdoor
MV Switchgear

Global Standards Compliance

Our power equipment meets IEC, NEMA, and GB standards. LV switchgear is IEC 61439 compliant with arc-resistant designs. MV equipment includes SecoGear (IEC/GB) and maintenance-free gas-insulated RMUs for secondary distribution up to 36 kV.
