MCCB for 100 A feeder protection
The Siemens 3VA2110-6HN32-0CH0 is a 3-pole SENTRON molded case circuit breaker rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to 70 °C. Its interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V, and still holds 121 kA at 500 V, so it handles high-fault utility feeds or transformer-secondaries where fault current runs high.
Built-in undervoltage release and auxiliary switches
The auxiliary switches give remote status feedback (open/closed/tripped) for a PLC or SCADA input.
The 105 mm width matches the common 3-pole slot in SENTRON distribution boards and most industrial enclosures. No special cutout or adapter needed for a standard panel.
