ESR ECO125 125A 240V Changeover Switch

The ESR ECO125 is a 125A single-phase manual changeover switch designed to safely transfer electrical supply between two power sources, such as mains power and a backup generator. This makes it an ideal solution for installations where a reliable alternative power supply is required during outages or maintenance.

Featuring a simple two-position switching mechanism, the ECO125 allows users to manually switch between power sources while ensuring the two supplies cannot be connected at the same time. The switch is supplied with a busbar connection and is suitable for installation in distribution boards or separate enclosures.

Built for durability and dependable operation, the changeover switch is commonly used in generator backup systems, solar installations, and other applications requiring manual transfer between power supplies.
