It uses a TM240 thermal-magnetic trip unit — the thermal element adjustable from 56 A to 80 A, the magnetic pickup set at 5 to 10 times In. That lets you fine-tune the overload threshold to the actual load current and set the short-circuit instantaneous trip high enough to ride through motor inrush. The integrated undervoltage release (UVR) at 24 V DC drops the breaker on loss of control voltage, standard for emergency-stop or undervoltage protection schemes. ## Deployment context The nut keeper kit (included) secures the line and load lugs — a detail that saves a trip back to the stockroom during a panel build. The UVR coil draws power continuously when the breaker is closed; if the control supply is shared with other loads, verify the 24 V DC source can hold the dropout voltage above the release threshold.","metaTitle":"Siemens 3VA1180-5EF32-0BH0 Circuit Breaker, 80A, 55kA @ 415V","metaDescription":"Siemens 3VA1180-5EF32-0BH0 IEC 3VA1 frame 160 breaker, 80A, 55kA @ 415V, TM240 thermal-mag, UVR 24V DC aux switches.
