The Siemens SENTRON 3VA2010-6HN36-0KL0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, designed for line protection in distribution panels and motor control centers. Its interrupting capacity reaches 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — figures that define its fault-clearing capability across common industrial voltage tiers.
What the ratings mean for fit
The 100 A continuous rating holds flat across the full ambient range from 40 °C to 70 °C — no derating needed up to the maximum operating temperature, which simplifies panel thermal budgeting. The 242 kA at 240 V is the headline fault-clearing number; it tells you this breaker can interrupt very high available fault currents at low-voltage distribution levels, typical of large transformer secondaries or generator paralleling. At 690 V the capacity drops to 3 kA, so verify the available fault current at the point of installation for 690 V systems. The breaker ships with a shunt trip (STL) auxiliary release and a complement of two auxiliary switches plus one trip alarm and one electrical alarm switch — a configuration suited for remote tripping and status feedback without adding external relay logic. No undervoltage release, no ground-fault monitoring, and no communication function are built in. Physical fit: 86 mm deep, 105 mm wide, 181 mm high. The 3-pole, 100 A frame mounts in standard panel cutouts for SENTRON 3VA fixed breakers. The trip indicator and voltage trigger are present on the front face for visual status.
