Heavy duty Zigbee, Z-Wave or Shelly control switch (230/415v, 16A/32A options)

This versatile unit provides the only plug-in solution in the UK for the automation of high power and inductive loads, with the option of Zigbee, Z-wave or Shelly (via Wi-Fi or LAN Ethernet) control. Simply plug in the unit between the appliance and supply socket to enjoy full automation. Great for remote operation, timer functions and taking advantage of lower energy tariff periods. We also provide this unit with standard Wi-Fi control via TUYA here.

Inductive vs Resistive Loads

Most automation controls use an integral relay, which is a cheap, compact way of controlling resistive loads. Resistive loads do not contain a motor and require a steady amount of current, even on start up e.g. lights.

In contrast, inductive loads contain a motor or coil e.g. power tools, pumps and refrigerators. When an inductive load is first powered up, it draws a much larger start up current, typically 2.5-3 times its normal operating current. For example a 500w drill may briefly draw 1250-1500w when it starts up. The main issue is actually caused when the relay contacts open to turn the tool off. The stored inductive energy in the motor coil is discharged, resulting in a damaging arc across the terminals, which can eventually cause the relay to fail. 

To overcome this issue, instead of using the relay within the Wi-Fi module to switch the load directly, our units connect the output to a high quality contactor, which then switches the load. Contactors work using the same principle as a relay , but they are much larger and far better suited to switching higher current inductive loads. The picture below shows the sheer size difference between a typical contactor (left) and relay (right); when it comes to switching inductive loads, contact size really does make a difference.

Specification:

• Select from a range of CEE connectors.
• Gewiss robust IP55 weatherproof DIN enclosure. Dimensions W105mm x H170mm x D98mm. 415v 32A unit uses a larger enclosure W180mm x H180mm x D98mm.
  
• 0.3m in/out of industrial specification H07RN-F rubber cable, specifically manufactured for harsh environments with high mechanical, chemical, water and UV resistance. Flexibility and performance is retained over a wide temperature range (-25 to 55°C). Find out what’s so special about this cable.
• Please note that the controller will not work if the appliance connected to it has a DoL motor starter or no-volt release switch (NVR). These commonly both have a start and stop switch. 
• Please contact us for custom cable lengths or connectors.
  
• PAT tested.
