MCCB for line protection — 100 A continuous, 242 kA interrupting
The Siemens SENTRON 3VA2110-6HN32-0HA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, with a maximum interrupting capacity of 242 kA at 240 V AC. At 415 V the rating holds at 187 kA, and at 690 V it drops to 3.7 kA, so the voltage-dependent curve governs where you place it in the distribution.
Shunt trip and thermal performance
The design is line protection (not motor or feeder), meaning the trip curve is shaped for cable and busbar protection.
