Siemens SENTRON 3VA2216-5HL32-0JH0 — 160 A Molded Case Circuit Breaker
The Siemens SENTRON 3VA2216-5HL32-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, with an adjustable overload trip range from 240 A to 1920 A. It's designed for line protection in distribution panels and motor control centers, where you need selective coordination and high fault current handling. Breaking capacity is substantial: 187 kA at 240 V, 121 kA at 415 V and 440 V, dropping to 75.6 kA at 500 V, and 4.5 kA at 690 V. That 187 kA figure at 240 V means it can safely clear a massive fault without rupturing — critical for high-capacity transformer secondaries or busway feeds where available fault current is high. Continuous current holds at 160 A across the full operating temperature range from -25 °C to 70 °C, so you don't lose capacity in a hot panel. The shunt trip (STL) release lets you remotely trip the breaker via a control signal — useful for emergency stops or interlocking schemes. Auxiliary contacts include two auxiliary switches plus one trip alarm switch (HQ configuration), giving you status feedback for PLC inputs or annunciator panels. The trip indicator and voltage trigger are present; undervoltage release and ground-fault monitoring are not fitted on this variant.
Dimensions and Panel Fit
Physical footprint: 105 mm wide, 181 mm tall, 86 mm deep. That 105 mm width is standard for a 3-pole MCCB in this frame size — it fits the usual DIN-rail or panel-mount cutout without surprises. Depth of 86 mm means it clears most standard enclosure backplates, but check your gland plate clearance if the breaker sits near the rear wall. Maximum power loss is 19.7 W, so factor that into your enclosure thermal budget — especially if multiple breakers are ganged in a sealed cabinet.
