What the ratings mean for fit
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 breaker is designed for line protection (feeder duty), not motor protection — the trip curve and accessories are configured for cable and busbar protection in distribution panels. It ships with a shunt trip release (STL) and a full auxiliary switch set: two auxiliary switches plus one trip alarm switch plus one electrical alarm switch (HQ configuration). The base switch variant is 3VA2216-5HL32-0AA0; this -0JL0 suffix adds the specified accessories and release.
Dimensions and panel fit
Physical footprint: 105 mm wide, 181 mm tall, 86 mm deep. 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.
Environmental and compliance
Operating temperature range is -25 °C to +70 °C; storage range is -40 °C to +80 °C. Maximum power loss at rated current is 19.7 W — a figure to include in the panel thermal budget if the enclosure is sealed. The breaker includes a trip indicator and a voltage trigger (shunt trip release). No undervoltage release, no ground-fault monitoring, and no communication function are fitted on this variant.
