2013 Product of the Year finalists: Power Transmission

Bypass isolation contactor

The 1600-A bypass isolation contactor provides robust monitoring, reporting, and transfer control operations to include an in-phase monitor. It’s equipped with dual automatic transfer switch (ATS) technology and supports concurrent maintainability through automatic control in the bypass mode for mission critical applications. ATSs are critical components to any emergency or standby power system because they can provide emergency power to life safety and other critical loads where maintenance of the main transfer switch, without interruption of power, is either desirable or required. The 1600-A bypass isolation contactor is UL1008 listed and CSA 22.222 No. 178-1978 listed.

Load-interrupter switchgear

The ArcGard load-interrupter switchgear is engineered to enhance operator safety during maintenance operations for industrial, commercial, and utility customers. The ArcGard medium-voltage switchgear features arc-resistant enclosures that can be shipped in a single structure, reducing customer costs and equipment space. This Eaton Green Leaf Label solution meets stringent standards of sustainability and efficiency. ArcGard is designed to protect personnel from dangerous arcing faults by controlling, collecting, and channeling the decomposition of the products from internal arcing faults to an area away from the perimeter of the gear. It incorporates arc chute and flicker blade technology to increase equipment life.

Metal-enclosed switchgear

The metal-enclosed load interrupter switchgear from Eaton provides reliable switching and fault protection of the medium-voltage circuits for industrial, institutional, and health care customers. This switchgear is engineered to reduce the footprint of electrical distribution systems in an environmentally friendly and compact design. Its 18-in.-wide structure with front-accessible cable terminations incorporates Eaton fuses for accurate, calibrated short-circuit detecting and interrupting capabilities to support power reliability. The metal-enclosed load interrupter switchgear uses flicker blade and DE-ION arc chute technology to prolong the life of the main blades by minimizing arcing between the main blades and the stationary contacts.

Combination panelboard

The Square D I-Line Combo Panelboard saves time and space by combining the I-Line and NQ/NF lighting sections into one panelboard. The I-Line Combo Panelboard features a smart, space-saving design for fast installation and a smaller footprint. The single panelboard is available in 26- and 32-in. widths with one NQ or NF lighting section. The duplex configuration is available in 32- and 44-in. widths, in either two hard-bussed lighting sections or one hard-bussed lighting section with open mounting space for field-installable options. The I-Line power section mounts horizontally, and is available in 18-, 22.5-, or 31.5-in. configurations.
