The Siemens SENTRON 3VA2116-5JQ32-0CH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection at 160 A full-scale, with a breaking capacity of 187 kA at 240 V and 121 kA at 415 V. It includes an undervoltage release and a communication function, making it suited for monitored distribution panels where remote trip indication and coordinated selectivity are required.
At 70 °C ambient, it still carries the full 160 A, which simplifies panel thermal budgeting. Breaking capacity steps from 187 kA at 240 V down to 3.7 kA at 690 V. The 121 kA at 415 V covers most industrial low-voltage fault levels in IEC 60947-2 installations; the 75.6 kA at 500 V handles higher-voltage motor circuits. At 690 V the 3.7 kA limit means this breaker is not the primary fault-interrupting device for 690 V feeds — use it as a downstream branch protector where the upstream device limits let-through.
Integration and deployment context
The 86 mm depth, 105 mm width, and 181 mm height footprint fits standard SENTRON 3VA panel cutouts.
