What this MCCB carries and where it fits
The Siemens 3VA1116-5ED32-0JC0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, meaning it sits at the feeder or main breaker position in a distribution panel, not downstream on a motor branch. It carries 160 A continuously at 40 °C ambient — that's the current it passes without tripping under normal load — and the rating holds flat to 50 °C before it starts to derate: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. For a panel that runs warm, the 40 °C figure is the one to spec against; the derating curve is already built into the breaker's thermal-magnetic trip, so you don't need to manually apply an external factor unless your ambient exceeds 70 °C. Breaking capacity is the number that decides whether this breaker survives a fault without welding contacts or venting gas. At 240 V it interrupts 187 kA; at 415 V it's 121 kA; at 440 V it drops to 75.6 kA; at 500 V and 690 V it holds at 17 kA. For a 480 V panel (common in North America), the 440 V figure is the closest published — 75.6 kA — which is well above typical available fault currents for most commercial and light industrial services. If your utility transformer can deliver more than 75 kA at 480 V, you need to verify the actual 480 V rating from the manufacturer, but for the vast majority of installations this breaker has headroom.
Panel fit and integration
The 3VA1116-5ED32-0JC0 is a 3-pole MCCB with a width of 76.2 mm (3 inches) and a depth of 70 mm (2.76 inches). The height is 130 mm (5.12 inches). Maximum power loss is 38 W at full load.
