SENTRON 3VM1116-3GD42-0AA0 — 160 A Line Protection MCCB
Its TM210 thermal-magnetic release provides fixed instantaneous and adjustable thermal protection, sized for the full 160 A rating — no derating needed at 40 °C, 45 °C, or 50 °C, where it holds the full 160 A. Breaking capacity runs 76 kA at 240 V AC, 53 kA at 415 V AC, and 32 kA at 440 V AC — enough for high-fault utility feeds without cascading upstream breakers.
Thermal Performance and Panel Fit
Dimensions are 70 mm deep, 101.6 mm wide, and 130 mm high — a compact 4-pole footprint that fits standard Siemens SENTRON distribution panel mounting. At 55 °C the breaker still carries 158 A, dropping to 150 A at 70 °C; the thermal curve means you can pack it into a warm enclosure without oversizing the frame. Maximum power loss is 38 W — factor that into enclosure ventilation when grouping several breakers.
No direct functional replacement is needed at this lifecycle stage — the part is the active release.
