3VA2110-6HL32-0HH0 — SENTRON MCCB, 100 A Frame, 242 kA Interrupting at 240 V
The Siemens 3VA2110-6HL32-0HH0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current Iu of 100 A at 40 °C through 50 °C, derating to 85 A at 70 °C. The interrupting capacity hits 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 5 kA at 690 V — that 242 kA figure at 240 V means it can safely clear a fault on a high-capacity transformer secondary or a large capacitor bank without the arc re-striking.
Trip Unit and Auxiliaries
Fitted with the ETU320 electronic overcurrent release — this is the basic electronic trip offering in the 3VA line, providing adjustable thermal-magnetic curves via DIP switches on the front face, not the full LCD of the ETU600 series. The shunt trip (STL) auxiliary release is built in (design of the auxiliary release: shunt trip), so a remote trip coil is already wired to the secondary terminals; no external undervoltage release is present.
That 86 mm depth is the critical dimension when recessing into a panel backplate — verify the enclosure depth allows for the rear-mounted terminals and the shunt trip wiring tray. Mounts directly to the DIN rail or the 3VA mounting plate; the 105 mm width occupies three 35 mm module spaces. Maximum power dissipation is 10 W, so no forced cooling required in a standard IP54 enclosure, but keep it away from heat sources like contactor coils or power supplies.
