Gas Density Relays for Switchgear Alarm and Lockout

Most switchgear density protection works in stages. The first stage warns that gas needs topping up, and the second blocks operation before conditions become unsafe.

Gas density relays with multiple independent, galvanically separated contacts handle alarm and lockout stages from a single device, keeping protection simple and wiring tidy.

From reference gas monitors with switching contacts to quartz sensors with 4-20mA or Modbus output, Trafag's range covers high and medium voltage applications. Explore the range for full specifications.
