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. At 690 V the rating drops to 3.7 kA, which still covers most industrial motor-circuit fault levels at that voltage.
Built-in undervoltage release and auxiliary switches
This MCCB ships with an undervoltage release (UVR) factory-fitted, plus two auxiliary switches and one trip alarm switch (HQ). The UVR trips the breaker when control voltage drops below its dropout threshold — standard for safety circuits that need to drop power on loss of control supply. The auxiliary switches give remote status feedback (open/closed/tripped) for a PLC or SCADA input. No communication module on this variant; it is a hardwired protection device.
Panel fit and mounting
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel installation. 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.
