Changeover Switch System

Transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual (MTS) in that an operator effects the transfer by throwing a switch, while others are automatic (ATS) and switch when they sense one of the sources has lost or gained power. In this purpose,we provide different solutions, upon customer requirement (breaker, contactors or changeover switch).

a). Automatic Transfer Switches (ATS)

Features

Available with different types :

  • ATS using contactors Up to 400A

  • ATS using motorized changeover switch up to 3200A.

  • ATS using motorized circuit breakers (ACB) up to 6300A.

  • ATS using motorized circuit breakers (MCCB) up to 1600A

Available Design verification to TTA as per latest standard IEC 61439-1&2.
