Building on the success of our popular heavy duty time switches, which provide the only plug-in timer solution in the UK for high power and inductive loads, our all black range provide the perfect solution for time controlling power at events. Simply set the time intervals and plug the unit in between the appliance and supply socket. 

Most timers use a 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 timer unit to switch the load directly, our units connect the timer 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.

Contactor rating:

Unit Resistive Inductive
230v 16/32A 40A (AC-7a) 15A (AC-7b)
415v 16/32A 63A  (AC-7a) 20A (AC-7b)


A plug-in Wi-Fi unit is also available as an alternative, to provide remote programming and switching. 

Specification:

  • Select from a range of IEC black connectors.
  • Digital programmable time switch.
  • Up to 16 on/off periods can be set for each day, minimum 1 min apart.
  • Manual over-ride to select permanently on or off.
  • Easy to program using clearly marked buttons.
  • Battery back-up to retain settings when power is disconnected (continual power provided for up to 3 years).
  • Robust black IP65 weatherproof DIN enclosure. 230v units overall dimensions W215mm x H145mm x D110mm, 415v units W325mm x H215mm x D110mm.
  • Lockable front cover to prevent tampering (key is universal for all units).
  • 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 timer 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.
