Onload Changeover Switch

When a power supply goes out, generally speaking, it will cause your entire operation to come to a complete stop. When switching between power sources, it is important that the transition is done successfully. The Onload Changeover Switch was designed to allow instant transfer of the load from the main to backup source without impacting the operation of currently connected loads.

Each Onload Changeover Switch unit has been designed for industrial use, so the contacts are capable of frequently switching and carrying high current loads. Thermal and mechanical limits have been tested and verified to ensure that the units can withstand multiple operations without losing functionality or reliability. The handle on each unit is completely accessible and operates safely, and the indicators for the current supply make it easy for the operator to see which source is supplying power, reducing operator errors.

Typically, we install Onload Changeover Switches in critical facilities (such as data centers), manufacturing facilities, cold storage facilities, or commercial buildings, where uptime is a critical issue. The units are designed to work in conjunction with distribution panels, MCCs, and APFC systems. Internal interlocks ensure that both power sources cannot be connected at the same time.

The commissioning of an Onload Changeover Switch includes testing to ensure that loads are transferred properly under real-world conditions, verifying that the transfer between sources is done smoothly and checking the integrity of the connection.

Maintaining an Onload Changeover Switch is easy because all components can be accessed and replaced as required.

The Onload Changeover Switch will provide reliable power, protect your equipment, and minimize downtime through the real-world design of the units. Each unit has been tested and certified prior to installation, and there are thousands of units in service across the United States.
