We are closed from the 20th of December - 5th January 2026.

Our product this month would be the Omega III

The Omega is an Earth Fault relay with a dual indicator – red LED and flag that can be operated from a Bowdens Band CT or a conventional cast resin core balance CT. 

It has user settable trip current, and trip duration settings, as well as a reset time range of between 3 and 12 hours. It can be powered by a replaceable long life lithium battery giving a 10 year average life under normal operating conditions or it can be powered from the incoming LV mains, in which case the option for LV supply reset is available. 

The indicator is driven by high capacity super caps whilst the LV supply is absent. This means that no batteries are required with the LV unit. The OMEGA III EFI has a high intensity red LED indicator as well as a black/red flag disc and the facility for a remote LED indicator external to the substation. It has two alarm output relays with either latching or fleeting function. OMEGA III may also be powered and reset from an RTU supply. It also has manual controls for Test and Reset.

Please note the last shipping date for 2025 is Wednesday 17th December

Hope you have a lovely Christmas and New Year too,
