Control and integration

Automatic changeover.
A considered specification.

Range features

  • Two-wire generator start signal
  • Removable bottom cable gland plate
  • Automatic, manual and test modes
  • LCD, password-protected keypad and programmable timers
  • Integrated manual handle and padlocking facility

Confirm any isolation or maintenance procedure from the instructions for the supplied equipment.

Options and configuration

  • IP54 enclosure option
  • Top cable entry, subject to model
  • RS485 communications module
  • Power metering and auxiliary contacts
  • Solid neutral and supply-available volt-free contacts
  • Surge-protection option

Options depend on the selected model and current build specification. Confirm every required function in your quotation.

Before you order

Match the system,
not just the amps.

Confirm the supply voltage, phase and frequency, neutral and earthing arrangement, load duty, fault level, protection, cable capacity and generator-start interface.

A standard open-transition ATS does not provide uninterrupted power or generator paralleling. Tell us if the load requires UPS support or a different transfer arrangement.
