Selectivity studies should use the voltage-specific value, not the highest number. The 17 kA floor at 690 V still covers most industrial 690 V feeder duty. ## Auxiliary and release configuration The auxiliary switches report breaker position; the trip alarm signals a fault trip separately from manual open. The UVR provides undervoltage protection — if control voltage falls below dropout threshold, the breaker opens. No ground-fault monitoring or communication function on this variant. ## Physical fit and environmental limits The trip indicator gives a visual flag on fault trip — useful for troubleshooting without opening the panel door.","metaTitle":"Siemens 3VA1180-5EF36-0BH0 SENTRON MCCB, 80 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1180-5EF36-0BH0 molded case circuit breaker, 80 A, 3-pole, 187 kA interrupting at 240 V.
