Distribution Switches
The LineBOSS™ Sidebreak switch is the most robust, yet elegant sidebreak switch in the market today. Every LineBOSS™ component brings meaningful operator benefits for years to come. Features such as 1/4 inch steel phase base, stainless steel to brass bearings, silver plated copper reverse loop contacts and busbar blades mean efficient and smooth operation over a very long life; even in hostile environments where dust, humidity, corrosives and other industrial or natural contaminants play havoc with most. You’ll be amazed with how much switch you can buy for the money. The LBS distribution switch is RUS accepted.

Transmission Switches
INERTIA Engineering and Machine Works, Inc. adapted the industry leading design features of its distribution class G.O.A.B. switches, to produce an extremely high quality and cost effective, unitized sidebreak style transmission switch.
The ease of installation that unitized distribution class switches provide is now available for transmission class switches. The phase units are shipped as completely factory assembles and adjusted units. The actual configuration is delivered fully unitized or modularized for fast, simple and easy field installation.
The LineBOSS™ 48 kV – 72.5 kV sidebreak switches are the lowest “cost to own” switches available today. Fully unitized or modular switches are hung on the pole in hours, not days. These switches also provide lower operating costs. Unbalanced conductor load or seasonal temperature changes can create line sag leading to contact misalignment on other style switches. This maintenance headache is eliminated by the LineBoss™ sidebreak switch. Custom phase bases are available for installation on a wide variety of structures.

Specialty Switches
The LineBOSS™ NBS, Nielsen Bypass Switch, was originally designed in 1972 by Carl Nielsen, P.E. to allow non-interrupting bypassing and energizing (cut-in or cut-out) fixed booster transformers. The NBS switch now provides continuous power to load-side customers when energizing or de-energizing one, two, or three phase fixed booster, auto-booster, and regulator transformers as required by voltage conditions or routine maintenance or replacement.
The LineBOSS™ loadbreak grounding switch, GBS, is uniquely designed to provide loadbreak, open gap clearances and line grounding for applications in substations or pole line switches. The GBS is available for two arm substation construction with switch bases manufactured to adapt to existing structures, or factory unitized on a single steel crossarm. The GBS is available with fused disconnects for additional system safety requirements. Control mechanisms are built with safety key interlocks to prevent the isolator (loadbreak) switch and the grounding switch from errant closure of both switches.

The INERTIA MSO, motorized switch operator, meets or exceeds ANSI certification standards for substation, transmission and distribution Supervisory Control And Data Acquisition (SCADA). It works as a stand alone, locally controlled device, or it can be fit with a wide variety of SCADA communication equipment including your choice of RTU, modem, radio, antenna, cabling, and analog insulators with current, voltage and fault sensing capabilities.
Two MSO models are:
- MSOD- reciprocating output for distribution switches 15 kV-35 kV
- MSOT- reciprocating output for transmission switches 46 kV-72.5 kV
The INERTIA MSO is built with interchangeable communication control modules for upgrading on the shop bench instead of in the field. A basic push-button operating device can be upgraded with a variety of SCADA systems in the future. A new or modified module, with your choice of remote control features, can be easily bench tested on an existing MSO series and quickly apply the upgrade in the field.
The INERTIA MSO gives the flexibility needed for your changing remote switching requirements. Inertia’s interchangeable modules allow for easy upgrades on the shop bench; not up on the pole.
