Mains - Mains 250 Amp ABB 3 Phase N

Mains to Mains Automatic Transfer Switch.

Automatic switching between Primary Mains & Secondary Mains

3 Phase + Neutral 4 Pole (400V) Automatic Transfer Switch Also Known As an ATS Panel.  

A phase failure relay is used for Mains / Primary voltage monitoring and offers Phase Failure & phase sequence Protection.

The Automatic Transfer Switch Control Panel has two-time control relays for on load delay. 1^st Timer normally set to 10s and is used to control the Primary Mains on load / Restoration period, this controls the period the Primary Mains supply has to be healthy before engaging the Mains contactor. The 2^nd Timer normally set for 15s controls the Secondary Mains contactor, On failure of the Primary / Mains supply,  The Secondary Mains 2^nd timer will initiate. The Automatic Transfer Switch will monitor the Primary / Mains, as soon as the mains is restored it will drop the Secondary Mains contactor and initiates the 1^st timer sequence, then automatically switches back to the Primary Mains supply,
