Siemens 3VA2116-7HL36-0AH0 — 160 A SENTRON MCCB with ETU320 Trip Unit
The Siemens 3VA2116-7HL36-0AH0 is a 3-pole SENTRON molded case circuit breaker rated for 160 A continuous current at 40 °C, with the same rating holding flat through 70 °C — no derating needed across the full operating temperature range. The interrupting capacity reaches 330 kA at 240 V AC, 242 kA at 415 V, and 187 kA at 500 V, dropping to 3.7 kA at 690 V. This is a high-interrupting MCCB sized for main or feeder protection in distribution panels where fault current levels are substantial. The electronic trip unit is an ETU320, a fixed-setting, non-communicating release with thermal-magnetic-like curves but better selectivity coordination than a thermal-magnetic breaker.
The 160 A rating is continuous at 40 °C ambient, and critically, it does not derate at 45, 50, 55, 60, 65, or 70 °C — the full 160 A is available all the way to the maximum operating temperature of 70 °C. That simplifies thermal calculations in a crowded enclosure. Power loss is 25.5 W maximum at rated current — a figure to include in enclosure thermal calculations, especially if multiple breakers are ganged in a single panel.
The breaker occupies 105 mm width × 181 mm height × 86 mm depth — a standard 3-pole MCCB footprint for 160 A frame size.
