What this 160 A MCCB carries
The Siemens SENTRON 3VA1116-5ED32-0DA0 is a 3-pole molded case circuit breaker rated 160 A continuous at 40 °C, with no derating up to 50 °C — it holds the full 160 A all the way to that point, then steps down to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Interrupting capacity is 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — so on a 400 V class panel it clears a 121 kA fault without upstream fuses, which covers most industrial service-entrance and feeder positions. Rated insulation voltage is 800 V, max power loss is 40.5 W, and it operates from -25 °C to 70 °C ambient. No ground-fault monitoring, no communication function, no voltage trigger — this is a straight line-protection breaker, not a multifunction power monitor.
Mounting and footprint
The 3VA1116-5ED32-0DA0 is a fixed-mount MCCB designed for DIN-rail or screw-mount panel integration. It measures 130 mm high, 76.2 mm wide (3 inches), and 70 mm deep — a standard 3-pole footprint that fits existing SENTRON 3VA panel layouts without re-drilling. No trip indicator window on the front face.
