1All Russelectric 4 pole Open Transition ATS’s have a fully rated -break before make- switched neutral, identical in every way to the main power poles and integrally designed into the switching mechanism.
9After machining and brazing all contact segments –movable and stationary- are silver plated before assembly.Russelectric 100a stationary & movable contact. (Golf ball shown for size reference).
10Over Center Spring Mechanism Transfer Switch Contacts(Design Concept)In an “over center,” (spring loaded design). The mechanisms which drive the contacts utilize a spring assisted motor operated concept. This design provides for a “quick-break, quick-make” operation, with full arc interruption, under maximum voltage and amperage. Unlike other manufacturers, the contact speed and closing pressure is not reliant on the speed of the motivator (i.e. Motor or Solenoid). With this design, life span, safety, reliability is dramatically increased and the unit may be safely transferred manually, under load.Over CenterSpring MechanismInitial Point of Contact

With this design, nothing can become misaligned, loose or misadjusted.Machined phenolic insulated separator.Lets look closer at the phenolic separator.Hardened steel, engineered, purpose machined parts for crucial reliability.Solid steel shaft, powder coated.

25Over Center Spring Mechanism Machining & WeldingRusselectric switches are welded in areas where others use fasteners… They are machined from hardened steel where others use stamped aluminum, cast white metal or even plastic, instead of machining from solid steel.Over CenterSpring Mechanism

30All welds on enclosures are MIG welded and ground smooth. All Metal Fabrication Performed in House.All Cabinetry is MIG Welded by Hand for Strength. Steel for Doors, Mounting, Side Sheets and Top and Bottom is a Minimum of 12 GaugeAll welds on enclosures are MIG welded and ground smooth.
31All Russelectric enclosures meet or exceed NEMA standards. There are no “spot” weldsin Russelectric’smetalwork.All corners and seams are hand welded and ground smooth.
