Metal Enclosed Switchgear

Metal Enclosed Load Interrupter Switchgear
Metal enclosed interrupter switches are most often used in data centers for protecting medium voltage transformers that service low voltage (480V) switchgear. The load interrupter switches are also useful for isolating cables between Metalclad breakers and transformers when maintenance is required. This equipment is ideal for applications where high duty cycle operation (switching) is not required and equipment cost is a concern. >more...   

Data Center Application

  • Primary protection (fusible) and isolation (non-fused) for medium voltage transformers

HVL/cc switchgear features ? 2.4kV to 38kV switching, control, and overload protection are ideal for water and wastewater applications. Improving reliability and performance are the primary goals of switchgear in any switching, control or protective application. We?ve taken these goals further with HVL/cc? medium voltage metal enclosed switchgear. Its exclusive operational features offer a higher level of system protection, yet it also incorporates innovative design features that reduce the risk of costly maintenance problems. The major differentiating features of HVL/cc switchgear include:

  • Smallest footprint in the industry (approximately one-quarter size of traditional medium voltage metal enclosed switchgear) ? makes it ideal for retrofit applications requiring increased load or duplex switches. Compact footprint fits easily through standard doorways
  • Compartmentalized construction ? the fuse/cable compartment is isolated from the main bus, while the main switch contacts are housed in a sealed interrupter
  • Low maintenance ? Sealed for life interruption saves time and expense with maintenance-free main contacts and ground switch contacts. Prevents switch contamination especially in harsh environments
  • Fault-making grounding switch (optional) ? prevents access to ?hot? fuse/cable compartment with mechanical interlock
  • Front access eliminates need for service space behind switchgear
  • FuseLogic system provides single-phase protection and blown fuse indication. This protects downstream motors from overheating due to negative sequence currents

No other medium voltage metal enclosed switchgear on the market offers these advantages. When you make the comparison based on installation simplicity, performance, and total cost of ownership, HVL/cc switchgear becomes the clear choice for system protection and reliability.
