The Siemens SENTRON 3VA2216-5HL32-0DC0 is a 3-pole molded case circuit breaker rated for 160 A continuous current, flat across the full operating range from 40 °C to 70 °C — no derating needed up to the maximum ambient. That means it holds its 160 A rating in a warm cabinet or near other heat sources, which is the spec that actually governs the bus bar and cable sizing. Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. The 105 mm width and 86 mm depth fit standard SENTRON panel cutouts; the 181 mm height leaves clearance for cable lugs and bus bar connections.
Sourcing and lifecycle — active, no end-of-life notice
Maximum power loss is 22.2 W, which is moderate for a 160 A frame — useful for thermal budget calculations in a sealed enclosure.
The 105 mm width occupies three 35 mm module spaces; the 86 mm depth leaves room behind the door for wiring and auxiliary contact blocks. Suitable for unconditioned electrical rooms and outdoor-rated enclosures within those limits.
