What this MCCB delivers
The Siemens 3VA1116-6ED46-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated 160 A at 40 °C, with 4 poles and a TM210 thermal-magnetic overcurrent release. The breaking capacity is 220 kA at 240 V, 154 kA at 415 V, and 75.6 kA at 440 V, so it handles high-fault utility feeds without cascading upstream. The TM210 release gives a fixed thermal curve and magnetic trip, no electronic adjustment. Front protection is IP40 — suitable for dry indoor panels; not rated for washdown.
Width is 101.6 mm (4 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). Verify the gland plate cutout matches the 101.6 mm width before drilling.
Current derating and thermal limits
Above that, derating is gradual: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C.
