The 3VA2216-5HL32-0JL0 is a Siemens SENTRON 3-pole molded case circuit breaker rated for 160 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up. Its adjustable thermal-magnetic trip unit covers 240 A to 1 920 A, so you set the actual protection point within that window to match the downstream load. 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; those numbers govern whether this breaker clears a fault before the upstream device has to intervene, which is the selectivity decision for the panel designer. The base switch variant is 3VA2216-5HL32-0AA0; this -0JL0 suffix adds the specified accessories and release.
That 86 mm depth (3.39 in) is the dimension that matters when the breaker mounts in a distribution panel with a door or deadfront clearance — verify the enclosure depth allows for the breaker body plus wiring space behind it. Width and height are standard for this SENTRON frame size; the 3-pole block occupies three 18 mm pole spaces on the DIN rail or mounting plate.
