Breaking capacity is the other headline: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V. The 70 mm depth, 105 mm width, and 158 mm height fit standard SENTRON 3VA panel cutouts; if you are replacing an older 3VA1 frame the footprint is the same. ## Internal configuration and auxiliaries This variant ships with the undervoltage release (UVR) factory-installed and two HQ auxiliary switches wired in — so it is ready for a safety circuit that drops the breaker on loss of control voltage, and for remote status feedback. The base switch is order code 3VA12164EF320AA0; the UVR is the design-of-the-auxiliary-release type, meaning it is integrated, not a field-add-on kit. No ground-fault monitoring, no communication function, no voltage trigger, and no trip indicator on this order code. It is a straight line-protection breaker with undervoltage release — clean, no extra electronics to fail.","metaTitle":"Siemens 3VA1216-4EF32-0BC0 SENTRON MCCB, 160 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1216-4EF32-0BC0 molded case circuit breaker, 160 A rated at 40-50 °C, 3-pole, 121 kA at 240 V.
