Solid state relay failure mode
Did you know?
WebTypical relay failure mode probability: Failure to Trip 55%. Spurious Trip 26%. Short 19%. As you can see, relays most commonly fail in the "stuck open" position where the mechanical switching element fails to close and the relay fails to carry a current. Relays are less likely to unintentionally close or remain closed after the switching ... WebOct 29, 2024 · The live wire for the machine circuit goes through a current sensing relay, which then turns on a 40A solid state relay, which switches the extractor live on and off. The motor on the extractor is a single phase 1500W ac motor with a single capacitor. I also wired in the motor thermal cutout, so that it switches off the 40A SS relay.
