Description
  • 4 Pole 100 Amp. to 630 Amp. 415V , 50 Hz 
  • HSN Code  85365010
SURDHI Innovation Throughout...
SURDHI Innovation Throughout...
The Surdhi 4-Pole On-Load Bypass Switch is a three-phase heavy-duty industrial switch operating at 415 Volts AC and 50 Hz frequency. It is widely used to isolate critical three-phase systems—like online UPS setups, solar inverters, or servo stabilizers—without dropping the electrical load or breaking continuity.
Frame Sizes & Standard Specifications
The range spans from 100 Amp to 630 Amp and is structured across three distinct physical frame dimensions:
    • Frame Size 01: Accommodates current ratings of 100A, 125A, 160A, and 200A.
    • Frame Size 02: Accommodates current ratings of 250A and 320A.
    • Frame Size 03: Accommodates higher capacities of 400A and 630A.
    • HSN Code: Classed under 85365010 for electrical switching apparatus.
Configuration & Terminal Layout
Because this is a 4-Pole (4P) Switch, it handles all three phases plus the neutral line simultaneously:
    • Poles Controlled: R-Phase, Y-Phase, B-Phase, and Neutral (N).
    • Safety Pre-break: The neutral pole features a quick-make, late-break mechanism to prevent voltage imbalances during heavy switching cycles.
    • Interlocked Terminals: Built with specialized interlocking layers to guarantee that the primary supply cannot accidentally feed back into the bypass supply
Available Mounting & Execution Types
Surdhi manufactures these products in two configurations
  • Open Execution: A bare switch mechanism without an outer box. This variant is designed for direct mounting onto a panel door, a distribution board, or inside a centralized industrial control cubicle panel.
  • Enclosed Execution: The switch comes pre-fitted inside a heavy-duty, powder-coated sheet steel enclosure. This box can be wall-mounted directly next to the machine it is bypassing.

Frame Size : 02
Amp. : 250
Open Execution Cat No. : SDV-BPS 250
Unit Price[₹] : 26933.00
Std. Packing : 1 Nos.
