NVR Switches

No voltage release (NVR) switches are safety devices that are commonly used in electrical circuits to prevent unexpected restarts of equipment or machines after a power interruption. They work by ensuring that power cannot be restored to the equipment until a deliberate action is taken to reset the switch.

NVR switches are typically used in applications where the sudden restoration of power could cause harm, such as in industrial settings where machines are in use, or in power tools used by construction workers. They are designed to be fail-safe, meaning that they will automatically trip in the event of a power interruption or loss of power, and will remain in the off position until they are manually reset.

Sinolec stock a range of KEDU NVR switches including rocker switch and push button NVR switches which are typically used for workshop equipment. Suitable as replacements for most appliances or for new projects. Fully approved with CE, TUV and or UL and VDE approval and compliant with RoHS with ratings of up to 18A 250Vac.

In addition to their safety benefits, NVR switches also offer a number of operational benefits. They help to prevent damage to equipment by ensuring that it is not restarted under potentially harmful conditions, such as when it is still in motion or when there is a mechanical malfunction. They also help to reduce downtime by preventing unexpected shutdowns due to power interruptions.
