All Russelectric 4 pole Open Transition ATSs 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.
Transfer Contacts Russelectric 2000 ampere rated movable finger contact Assembly Machined from Extruded Copper and Silver Plated A Critical Component:
Superior Mechanical Design, Most Rugged Construction… 800 Ampere ATS Contact with Arc Chute Assembly 800 Ampere ATS Contact with Arc Chute Assembly Tungsten on every arcing tip Machined from solid copper bar …Then Silver Plated
Contact Parts Precision Machined from 100% Extruded Copper Bar Stock. Not Cast/Forged or Stamped.
brazed 1. Each and every segment gets a tungsten element brazed to it, by hand. Tungsten protects the copper from high heat during arching and dramatically extends the life time of the part.
… Hand Assembled…
After 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).
Over Center Spring Mechanism Initial Point of Contact 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. Transfer Switch Contacts (Design Concept)
Close-up of a Russelectric connecting assembly to connect the movable contacts to the actuator shaft. With this design, nothing can become misaligned, loose or misadjusted. Machined phenolic insulated separator. Solid steel shaft, powder coated. Hardened steel, engineered, purpose machined parts for crucial reliability. Lets look closer at the phenolic separator.

Russelectric 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 Center Spring Mechanism Machining & Welding
