Standard ATS Panel 275A 4 Pole
275A (AC1) 4 Pole Mains to Generator Automatic Transfer Switch.
This panel is used for automatic switching between Mains & a Standby Generator.
3 Phase + Neutral 4 Pole (400V) Automatic Transfer Switch which is also Known as an ATS Panel.
A phase failure relay is used for Mains voltage monitoring and offers Phase Failure & phase sequence Protection.
The Automatic Transfer Switch Control Panel has two-time control relays for on load delay.
The 1st Timer normally set to 10s and is used to control the Mains on load / Restoration period, this controls the period the Mains supply has to be healthy before engaging the Mains contactor.
The 2nd Timer normally set for 30s controls the generator settling period, this time period ensures the generator has run up to speed and has stabilised before any load is applied to the generator.
On failure of the Mains supply, this initiates a volt free contact (N/O) start signal to the generator.
Upon the generator starting the 2nd timer will initiate, Then after this period, the generator will then go onto load.
The Automatic Transfer Switch will monitor the Mains, as soon as the mains is restored it will drop the generator contactor and initiates the 1st timer sequence, then switch automatically back to the Mains supply,
Once the load has returned to the Mains supply the generator start signal is removed and the generator will settle.
