Siemens SENTRON 3VA1116-5ED32-0HA0 — 160 A MCCB for Line Protection
It carries a 160 A continuous rating at 40 °C across all three poles, with a slight thermal derating curve that holds 158 A at 55 °C and 150 A at 70 °C — useful to know if the breaker sits in a warm enclosure or near other heat sources. Breaking capacity is 187 kA at 240 V AC, dropping to 121 kA at 415 V and 75.6 kA at 440 V — figures that cover most commercial and light industrial fault levels. At 690 V it still interrupts 17 kA, so it can serve 480Y/277 V or 600 V class panels where the available fault current stays within that envelope.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole footprint that fits standard Siemens SENTRON mounting bases and busbar systems. Depth of 70 mm (2.76 in) is compact enough for shallow enclosures; verify the busbar or cable exit clearance against the 70 mm projection from the mounting plane.
