Siemens 3VA1116-5EF36-0JH0 — 160 A MCCB with TM240 Release and Shunt Trip
The interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — figures that define its fault-clearing capability at each voltage level and directly govern selectivity coordination with downstream devices. The auxiliary trip accessory is order code 3VA9688-0BL32. The breaker is rated for 15,000 mechanical/electrical endurance cycles. Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard 3-pole MCCB footprint for panel mounting.
Current Rating vs. Ambient Temperature
Above that, the continuous current derates: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. For a panel running warm, the actual load limit is the derated value at the enclosure's internal ambient — not the 160 A nameplate.
