The Siemens SENTRON 3VA2216-5HL32-0KC0 is a 3-pole molded case circuit breaker rated for 160 A continuous current, designed for line protection in distribution panels. It carries a shunt trip release (STL) and two auxiliary switches HQ, so it can be remotely tripped and its status reported back to a PLC or annunciator — useful when you need to kill power from a control room or interlock with a safety circuit.
Breaking capacity — what it means at your voltage
The interrupting rating varies with system voltage: 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. At 415 V — common in industrial distribution — 121 kA is well above typical available fault currents for most plant switchboards, so you have headroom for selectivity coordination without needing a current-limiting breaker upstream.
Thermal performance and power loss
Rated current holds flat at 160 A from 40 °C through 70 °C ambient — no derating needed across the typical panel operating range. Maximum power loss is 19.7 W, which is moderate for a 160 A frame; plan for that heat in a sealed enclosure if you're stacking multiple breakers.
Panel fit and dimensions
Mounts in a standard MCCB footprint: 105 mm wide, 181 mm tall, 86 mm deep. The 3-pole body fits distribution panelboards and motor control center buckets sized for 160 A frames. No special cutout beyond the standard 3-pole MCCB opening.
