Siemens SENTRON 3VA2010-5HL32-0JH0 — 100 A MCCB for Line Protection
The Siemens SENTRON 3VA2010-5HL32-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed specifically for line protection in distribution panels. It carries a maximum breaking capacity of 187 kA at 240 V AC, stepping down to 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V — the voltage-dependent curve that governs fault clearing in your system.
What the Ratings Mean for Your Panel
The 100 A continuous rating holds flat across the entire ambient temperature range from 40 °C to 70 °C — no derating needed up to the maximum operating temperature, which simplifies panel layout when the breaker sits near other heat sources. Breaking capacity of 187 kA at 240 V means this MCCB can safely interrupt a fault current up to that level without upstream cascade — critical for high-available-fault-current installations like transformer secondaries or large motor control centers. At 690 V the rating drops to 3 kA, so verify your system's available fault current at the point of installation. Power loss is 13.5 W maximum at rated current — a figure to account for in enclosed panel thermal calculations, especially when grouping multiple breakers.
Auxiliary and Release Configuration
This variant ships with 2 auxiliary switches plus 1 trip alarm switch (HQ configuration), and a shunt trip release (STL) for remote tripping. The trip indicator and voltage trigger are present; undervoltage release is not included on this order code. No ground-fault monitoring or communication function is fitted.
Physical Fit and Panel Integration
Dimensions are 181 mm height, 105 mm width, 86 mm depth — a standard 3-pole MCCB footprint that mounts on a DIN rail or directly to a backplate. The depth of 86 mm (3.39 in) fits most shallow enclosures; verify clearance for the shunt trip wiring and auxiliary switch connections.
