The ZEN78 High Power Relay is designed for safely automating and controlling heavy-duty 240VAC appliances. With a 40A rating and built-in overcurrent protection (triggering at 40.5A), it provides reliable performance while helping protect connected equipment.

Key Features

• High Power Capacity: Handles loads up to 40 amps at 240VAC.

• Double-Pole Switching: Two independent 40A relays disconnect both hot legs (L1 and L2) simultaneously, ensuring safe shutoff.

• Manual & Remote Control:

  • Dry contact switch terminal for connecting a mechanical wall switch.

  • Onboard action button for local on/off control, Z-Wave inclusion/exclusion, and factory reset.

• Integrated Safety Features:

  • Overcurrent protection at 40.5A.

  • Temperature sensor for monitoring and added protection.

• Z-Wave Compatibility: Control and monitor the relay from your compatible Z-Wave hub or smart home system.

• Indoor Use Only: The ZEN78 is not IP66 rated and must be installed indoors or in a protected enclosure.

When to Use the ZEN78 High Power Relay

The ZEN78 is ideal for high-power 240VAC applications up to 40A, where both hot legs need to be safely disconnected. Common use cases include:

• Pool Pumps

• Electric Water Heaters or Boilers

• Air Compressors

• Air Conditioners / Mini Splits

• High-Power Outlets

• Shop Vacuums

• Commercial Lighting

• Heated Driveways

• EV Charging Stations

• High Power Appliances (Ovens, etc.)

• Electric Heaters

Important Notes

• The ZEN78 must be installed indoors or inside weatherproof housing within the rated temperatures if used outdoors.

• Installation should be performed by a licensed electrician due to the high-voltage and high-current nature of the device.

• Always verify load requirements before connecting to ensure safe operation.
