Siemens SENTRON 3VA2116-5JQ32-0BC0 is a 3-pole molded case circuit breaker rated for line protection, with a full-scale current of 160 A that holds flat across the ambient range — still 160 A at 70 °C, not derated until you push past that. The interrupting capacity hits 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA figure at 240 V tells you this breaker is sized for high-fault panels where the upstream transformer can dump serious energy — think service entrance or main feeder duty in industrial switchgear. The 105 mm width and 181 mm height fit standard SENTRON MCCB panel cutouts; depth at 86 mm leaves room behind the gland plate for cable bending radius. Undervoltage release (UVR) is built in, and the auxiliary switch pack provides two HQ-rated contacts for status feedback to the PLC or safety circuit. Communication function is present on this variant — no separate comm module needed for basic trip-signal reporting.
Integration & Mounting
Mounts on a DIN rail or direct panel-mount via the SENTRON base plate. The 3-pole footprint with 105 mm width means three of these side by side consume 315 mm of rail — plan your enclosure fill factor accordingly. Power loss is 28 W maximum at rated load, so account for that heat in a sealed cabinet; forced ventilation or a larger enclosure may be needed if multiple breakers are ganged.
