What this 100 A MCCB carries
The Siemens SENTRON 3VA2110-6JQ36-0AA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C through 70 °C — no derating needed up to that ceiling. Breaking capacity hits 242 kA at 240 V, 187 kA at 415/440 V, and still holds 121 kA at 500 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream.
The optional motor drive (listed as a product extension) allows remote charging for motor-operated switchgear applications.
The 100 A rating at 70 °C means this breaker can sit in a warm panel — near a transformer or drive — without you having to oversize the frame. The ETU560 electronic trip gives you curve-shaping flexibility (LSIG) that a thermal-magnetic can't match, and the built-in ground-fault monitoring (summation current) saves adding an external GF relay for most line-to-ground protection schemes.
