Add-On Type Terminals

Switches Add-On Type Terminals
ADD-On Type Terminals Blocks

The development of SURAJ open terminal blocks follows the most recent developments in terminal block design. PBT, or high-grade polybutylene terephthalate, is the insulating foundation material. PBT is a material that is unbreakable, non-hygroscopic, highly insulating resistant, and able to endure high impulse voltages.

High electrical grade phenol formaldehyde resin (Bakelite), which has a very high capacity to tolerate high voltage spikes and insulation, is used to make 100A terminal blocks. Superior grade copper alloys with the ideal ratio of copper to zinc are used to make the electrical conductors, resulting in low temperature rise and little transmission loss of electric current within predetermined bounds.

Brass and stainless steel 304 grade are also available as custom options for the high tensile mild steel screws and washers.

The mild steel screws underwent zinc passivation, utilizing a particular grade of zinc that is resistant to corrosion even under extreme conditions for extended periods of time. Bright nickel is applied on brass screws.

Add-On Type Terminals :

Add-On Type Terminals are specialized electrical connectors or terminal blocks that allow additional connections to be made to an existing wiring system without interrupting the primary circuit. These terminals are designed to facilitate easy expansion of electrical systems by enabling extra wires to be connected to the same terminal point.

These blocks typically "SNAP" onto DIN rails or other mounting surfaces and enable additional wiring connections without requiring significant changes to the existing setup. They are commonly used in control panels, electrical distribution systems, and other applications where additional connections may be needed after the initial installation.

Technical Specifications :

  • Insulating Material : Phenol formaldehyde resin (Bakelite)
  • Ways : Single with End plate
  • Rated operating voltage : 500 V. AC
  • Rated and uninterrupted current : 30A & 100 A
  • Ambient temperature : -10 °C to 55 °C
  • Rated operating frequency : 50 Hz/60 Hz
