Higher isolation margin
A 15kV class relay is selected when the system needs more stand-off margin than lower-voltage PCB relays can provide.
15kV HV Reed Relay
15kV Reed Relays for High-Insulation Switching
15kV reed relays are used where high stand-off voltage and compact controlled switching are required in test systems, cable fixtures and high-voltage instrumentation.

What this component is used for
Fixture-level integration
Used in automated test fixtures, safety testers and high-voltage routing panels where channel count and repeatability matter.
Measurement integrity
Guarding, shielding and clean layout help preserve low leakage measurement performance at high voltage.
Application details
Cable and backplane testing
Route HV test potential to selected conductors while isolating adjacent channels.
Power electronics production test
Switch high-voltage stimulus or sense paths in inverter, DC bus and insulation monitoring test equipment.
Medical equipment test
Support production validation of high-voltage modules without claiming equipment-level certification.
Custom HV matrices
Combine multiple relays into application-specific matrices with engineered spacing and safety interlocks.
Selection factors engineers should confirm
- Differentiate stand-off voltage, switching voltage and carry current.
- Validate capacitive load energy before switching.
- Use suitable wire, connector and PCB spacing for 15kV operation.
- Confirm coil suppression, drive voltage and thermal rise.
- Review regional safety standards at equipment level.
Engineering note: At this voltage class, the layout around the relay is as important as the relay itself: contamination, humidity, creepage and cable routing can dominate leakage performance.
