Three Phase Load Calculation
Delta Connected Load:
P = 1.73 × VL × IL × cosφ
P = 3 × VL × IL × cosφ
For resistive loads, cosφ = 1.0
Wye Connected Load:
P = 1.73 × VL × IL × cosφ
P = 3 × VP × IL × cosφ
For resistive loads, cosφ = 1.0
Quick Formula
Where P = total 3-phase power in kW:
For VL = 480V → IL = 1.2 × P (in kW)
For VL = 240V → IL = 2.4 × P (in kW)
For VL = 208V → IL = 2.8 × P (in kW)

- Switch rating: 10A/250VAC
- Shape: Flat head
- Terminal: Pin terminal
- Crust material: stainless steel
- IP rating: IP65 / IP67 can be customized
- Temperature: - 40 to 75 Degree
EMERGENCY STOP SWITCHES
Emergency stop buttons are wired in series with the control circuit of machinery equipment. When pushing the mushroom head of emergenty stop button will break the circuit of machinery equipment and removes power supply from the that keeps the circuit energized
ROCKER SWITCH
Rocker switches are electromechanical devices that control the start or stop function in circuits. They use an actuator that rocks along the center axis. These switches, commonly found in power supply boards and electronic equipment, ensure reliable long-term functionality.
