The LSN4-310-A EE Controls Contactor is designed for reliable performance in various electrical applications. With a compact design and high durability, this contactor supports efficient control of motors and other loads. Ideal for both residential and commercial use, it ensures seamless operation and longevity in demanding environments. Perfect for hot tub installations.
The LSN4-310-A is most commonly used for controlling motor loads in hot tub and spa installations, HVAC equipment, pumps, and general 3-phase or single-phase load switching. Its wide coil voltage range (120–575 V) makes it adaptable to many residential and commercial control circuits across Canada.
The LSN4-310-A may serve as a functional replacement for other 3-pole, 9/25A contactors with matching coil voltage and pole configuration from brands such as Siemens, Eaton, or Schneider Electric — provided the coil voltage, mounting style, and terminal dimensions are compatible. We recommend sending us the original part number so our team can confirm a direct cross-reference before ordering.
Yes — the LSN4-310-A is well-suited for hot tub and spa applications, which is one of its noted uses. In Canada, hot tub wiring must comply with the Canadian Electrical Code (CEC), which typically requires a disconnect within sight of the unit and specific bonding requirements. Always verify your coil voltage and load current against your spa's specifications, and consult a licensed electrician for final installation.
