The integrated undervoltage release (UVR) at 24V DC trips the breaker on loss of control voltage — common in emergency-stop chains or safety circuits where a sustained undervoltage must open the load.","metaTitle":"Siemens 3VA1020-4ED36-0BC0 Circuit Breaker, 20A, 36kA @ 415V","metaDescription":"Siemens 3VA1020-4ED36-0BC0 IEC 3VA1 frame 100 breaker, 20A TM210, 36kA Icu @ 415V, UVR 24V DC, 2 auxiliary switches.
