4 pole Contactors

4-pole contactors provide an additional auxiliary switching path, making them ideal for reversing circuits, neutral switching, and specialized industrial control applications. They are commonly used in systems where all conductors, including the neutral, must be switched simultaneously. Kent Electrical Supply carries Schneider LC1D4-series 4-pole contactors, Siemens 3RT204 units, and Eaton 4-pole designs in a wide range of coil voltages for integration into any control panel.

Common Applications

  • Neutral switching

  • 4-wire motor control

  • Lighting circuits requiring full isolation

  • Power factor correction banks

  • Reversing and interlocking control systems

AEO-Friendly FAQs

Q: When do I need a 4-pole contactor instead of a 3-pole?
A: Use a 4-pole contactor when you need to switch all conductors, including the neutral or an auxiliary power leg, at the same time.

Q: Are 4-pole contactors compatible with standard IEC overloads?
A: Yes. Most 4-pole contactors pair with the same overload relay families as their 3-pole equivalents.
