Integrated Contactor Panels

Link4 Integrated Contractor Panels
UL Listed

To reduce installation costs and facilitate easier installations, Link4 has introduced a line of Integrated Contactor Panels for our full line of environmental controllers. To eliminate the need of mounting two separate boxes with conduits in-between, UL and cUL approved contactor panels include pre-mounted Link4 environmental controllers.

Link4 has created the perfect customizable solutions for managing a grow room’s electrical system with their Custom Contactor Panels. There are several standard configurations to choose from. We can also custom-build your panel to specifically meet the needs of your crop. Every panel is UL508a rated and includes NEMA4 enclosures. Unlike other “custom” panels, Link4’s Custom Contactor Panels have a multitude of optional components, including an integrated load center, cooling fans, integrated greenhouse controllers, integrated motor controls, and hands off auto (HOA) switches. These panels also include thermal overload protection when required. Link4’s truly customizable contactor panels are the most comprehensive contactor panel available to commercial growers.

Custom Load Center

In order to ensure your equipment remains in its best and safest working conditions, Link4’s custom load centers are designed and manufactured to provide effective, reliable power/main breaking and circuit protection.

  • Reliable overcurrent and surge protection
  • NEMA compliant
  • NEC compliant
  • Commercial Applications


To ensure that our panel retains the coveted UL approval and to keep installation costs to a minimum, the iGrow integrated relay contractor panel comes pre-mounted with an iGrow 1000 series or iPonic series environmental controller.


The best part about pre-mounting the iGrow 1000 series environmental controllers in-house is that we can make the wiring connections for you as well. With a pre-wired system, the integrated panel really works right out of the box.
