Sectionals are terminal blocks which are made up of individually molded units with electrically conductive members. Marthon offers barrier sectionals from 3/8" to 1/2" pitch, Euro styles sectionals from 5mm to 12mm pitch with fusing, disconnection and grounding options. These sectionals will mount on either a standard 35mm DIN rail, channel rail, or panel (anchor directly).
The voltage ratings of terminal blocks are based upon the minimum spacing between electrically conductive parts line-to-line through air and over surface and line-to-ground through air and over surface.
Class A - Service, including deadfront switchboards, panel boards and service entrance devices.
Class B - Commercial appliances including business equipment and electronic data processing equipment.
Class C - Industrial, general
Designed for electrical termination of wire where flexibility of circuit design is necessary. Accept single or multiple wire sizes for tubular screw and tubular clamp styles.
