Transfer Switches
Transfer Switch Equipment is applied to any application requiring switching operations from one power circuit to another. A transfer switch connects to an alternative source of power to continue supply to electrical loads downstream. Available options include manual, remote (motorised) and automatic transfer switches.

Automatic Transfer Switches
Automatic transfer switches (ATS) provide a solution for reliable, rapid transfer between primary and alternative power to ensure the availability of electrical power in critical facilities (high-rises, public buildings, hospitals, IT or telecommunications centres, airports, industrial sites, etc.). ATS equipment can operate autonomously without human intervention after the initial commissioning and parameter set up stage. The design philosophy is similar to a Remote Transfer Switch, but integra...
Manual Transfer Switches
NHP offers a complete range of manual multi-polar changeover and bypass switches that provide safe and reliable transfer between two sources of incoming power supply. They are available in standard or visible break contact variants with a comprehensive range of accessories including mechanical interlocking. Manual transfer switches are operated locally by personnel, via direct mounted or external panel mounted handles, which allows direct control and time to assess the availability and readines...
Remote Transfer Switches
Remotely operated switches allow the transfer from one power source to another (transformer/transformer, transformer/gen set etc.) to ensure the availability of electrical power downstream of the device. With no integrated logic, remote transfer switches are designed to be operated via an electrical signal, volt-free contacts, or other external control (e.g. Socomec transfer switch controllers), providing a more flexible option for applications where transfer a switch is required to be predomina...
