The interrupting ratings step down with voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V and 690 V (–). ## Built-in undervoltage release The TM210 release is the overcurrent element; the UVR is separate and wired to the control voltage. The 70 mm depth keeps it within typical enclosure depth allowances for wall-mount panels.","metaTitle":"Siemens 3VA1080-2ED36-0DA0 SENTRON MCCB, 80 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1080-2ED36-0DA0 molded case circuit breaker, 80 A rated at 40 °C, 52.5 kA at 240 V, 3-pole, line protection with undervoltage release.
