Siemens SENTRON 3VA2010-6HL32-0CH0 — 100 A MCCB with Undervoltage Release
The Siemens SENTRON 3VA2010-6HL32-0CH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in distribution panels. Its interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V, giving you serious fault-clearing headroom for high-fault installations like transformer secondaries or large motor control centers. The built-in undervoltage release (UVR) drops the breaker if control voltage falls below the dropout threshold — a standard requirement for safety circuits that need to kill power on loss of control supply. Two auxiliary switches plus a separate trip alarm switch (HQ) provide status feedback to a PLC or annunciator panel.
Breaking Capacity and Selectivity Planning
At 240 V the 3VA2010-6HL32-0CH0 clears 242 kA symmetrical — that's a full-range fault rating, not a conditional short-circuit current rating (SCCR). At 415 V it still holds 187 kA, and at 500 V it's 121 kA. Only at 690 V does it drop to 3 kA, which is typical for a 100 A frame at that voltage. For selectivity coordination downstream of a larger SENTRON feeder, the 100 A continuous rating and the high interrupt capacity let you zone the panel: a 100 A branch can be selectively coordinated with a 400 A main breaker using the manufacturer's selectivity tables, provided the let-through energy of the upstream device is below the withstand rating of this breaker.
Panel Fit and Mounting Dimensions
The 3VA2010-6HL32-0CH0 measures 86 mm deep, 105 mm wide, and 181 mm tall. It mounts on a DIN rail or directly to a backplate via the breaker's base. The 105 mm width means it occupies three standard 35 mm module positions side by side — plan for 108 mm minimum clear width per breaker to allow for wiring gutters on each side. Depth of 86 mm fits standard 200 mm deep enclosures with room for rear-connected busbars or cable lugs. The trip indicator and auxiliary switch terminals are accessible from the front, so you don't need side clearance for status wiring.
