ABB offers a wide variety of manual change-over switches, from 16 to 3200 Amperes in range. Manual change-over switches are available with three different transition types.
Type TH heavy duty safety switches are designed for commercial and industrial applications where safety, high performance and continuity of service are essential.
Type TC and TDT double-throw safety switches are designed for applications with two sources of power where safety, high performance and continuity of service are essential.
Type TC emergency power transfer switches are designed to permit the connection of power from a standby generator or other emergency source of electricity.
