160 A MCCB with ETU850 — line protection for high-fault panels
The Siemens SENTRON 3VA2116-0KP36-0AA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current at 40 °C, with a maximum breaking capacity of 440 kA at 415 V AC and 187 kA at 690 V AC. It uses the ETU850 electronic overcurrent release, configurable for line protection, and includes communication functionality for integration into monitored distribution systems.
Breaking capacity and thermal performance
At 415 V AC, this MCCB interrupts fault currents up to 440 kA — suitable for high-available-fault panels where standard 65 kA or 100 kA breakers would not clear a bolted fault.
