The Siemens 3VA2010-6HN32-0DH0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current in a 3-pole configuration, designed for line protection. It carries a 242 kA interrupting capacity at 240 V — that's the number that matters for fault-current duty at the service entrance or on a high-fault panelboard tap. At 415 V and 440 V it still holds 187 kA, dropping to 121 kA at 500 V, and 3 kA at 690 V. This is a breaker built for heavy industrial fault duty, not a light commercial branch device.
Fault duty and selectivity
The 242 kA at 240 V means this breaker can sit upstream of a panel with a high available fault current — no need for a current-limiting fuse ahead of it in most installations. The 187 kA at 415 V and 440 V covers European and Asian industrial voltages. At 690 V the 3 kA rating is lower, so verify coordination if the breaker is applied on a 690 V system with significant fault potential. The 100 A rating holds flat across 40 °C to 70 °C ambient — no derating required up to that temperature range, which simplifies panel layout in warm environments.
What's on the frame
This order code ships with an undervoltage release (UVR) built in — the entry confirms it — plus a complement of two auxiliary switches and one trip alarm switch (HQ type). The UVR means the breaker drops out if control voltage is lost, which is standard for emergency-stop chains and safety circuits. The auxiliary switches give you status feedback to a PLC or indication panel. The trip indicator shows a mechanical flag when the breaker has tripped on fault, not just been switched off. No ground-fault monitoring on this variant, so if you need GF protection, that's a different order code or an external module.
Physical fit and environment
Dimensions are 86 mm deep, 105 mm wide, 181 mm tall — that's a standard MCCB footprint for this class. The 105 mm width means it occupies three pole spaces on a DIN rail or panel-mount base. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C. Power loss is 16 W maximum at rated load, which is modest for a 100 A breaker — helps keep enclosure internal temperature down.
