Surge protection devices and CNC protection relays include AC and DC surge protectors, overvoltage and undervoltage relays, and models with overcurrent protection. These components suit shoppers selecting protection for an electrical installation. The main selection criteria are the circuit’s current type and voltage, the pole configuration, and the required protection functions, with self-recovery specified on selected relays.

Surge protection devices and CNC voltage protection relays cover several electrical protection requirements. The range includes AC and DC surge protection devices, overvoltage and undervoltage relays, and relays with overcurrent protection. Selected relay descriptions specify DIN rail mounting or self-recovery. Identifying the required function provides a useful starting point before comparing electrical ratings.
Choosing surge protection devices and voltage relays
Match the device to the circuit’s current type, voltage and required pole configuration. Then compare the functions and ratings relevant to that device type. A relay’s rating in amperes and a surge protector’s figures in kiloamperes are separate specifications, so they should not be treated as one common comparison scale. Check the complete specification of the selected model.
- Voltage protection relays: Models include protection against overvoltage and undervoltage. Some relay titles also specify overcurrent protection, providing another function to consider when narrowing the selection.
- Self-recovery: Selected relays explicitly include this feature. Check the individual relay description when automatic recovery is a requirement for the installation.
- AC surge protection devices: AC models are offered with different pole counts. Compare their stated voltage alongside the other electrical specifications required for the circuit.
- DC surge protection devices: DC models carry Class B or Class C designations. Their voltage and kiloampere figures provide additional points for comparing individual devices.
- Poles and mounting: Configurations include 1P, 2P, 3P, 4P, 1P+N and 3P+N. DIN rail mounting is explicitly listed for several relays.
For voltage monitoring requirements, compare relay functions first. For AC or DC surge protection, focus on the corresponding device ratings. This keeps comparisons tied to the intended electrical protection task.
Frequently Asked Questions
Are surge protection devices available for DC circuits?
Surge protection devices include models explicitly marked DC. Select a DC device using its stated voltage and pole configuration alongside the circuit requirements.
Which relays include undervoltage protection?
Voltage protection relays described as overvoltage and undervoltage protectors include both named functions. Selected relay models also list overcurrent protection.
Do all voltage protection relays have self-recovery?
Self-recovery is explicitly listed for selected 1P+N and 3P+N voltage protection relays. Check the selected relay’s description to confirm this feature.
