SENTRON 3VA1116-4ED16-0AA0 — 160 A single-pole MCCB with TM210 release
The Siemens 3VA1116-4ED16-0AA0 is a SENTRON molded case circuit breaker rated for 160 A continuous current in a single-pole (1P) form factor. It carries a TM210 thermal-magnetic overcurrent release with LI protection — meaning it provides both overload (thermal) and short-circuit (magnetic) protection in one device. The fixed short-circuit release trips at 1600 A (10× Iu), so it clears hard faults fast without adjustment.
Breaking capacity and voltage ratings
Rated breaking capacity hits 75.6 kA at 240 V AC — that covers most North American panelboard fault levels with headroom. At 415 V AC it drops to 9 kA, which is still adequate for many European industrial networks where the prospective short-circuit current stays under that threshold. For DC circuits the maximum operational voltage is 125 V, so it works in DC branch protection or battery distribution applications within that limit.
Thermal derating and panel integration
Full 160 A rating holds up to 50 °C ambient. Above that it derates linearly: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. If the panel runs hot — say a packed enclosure with drives — factor that derating into the load schedule. The 25.4 mm (1 in) width per pole means this single-pole unit occupies one standard DIN slot; depth is 70 mm (2.76 in), height 130 mm (5.12 in). Front IP40 protection keeps tools and fingers out but it's not sealed against washdown.
