What this 3VA2116-6HL32-0KC0 brings to the panel
The Siemens SENTRON 3VA2116-6HL32-0KC0 is a 3-pole molded case circuit breaker (MCCB) built for line protection, carrying a rated continuous current Iu of 160 A with an ETU320 electronic trip unit. Its interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V, so it handles serious fault currents without letting the arc climb upstream — that's the kind of headroom that keeps a selectivity study simple. The 160 A rating holds steady from 40 °C up to 50 °C, then derates to 154 A at 55 °C and 136 A at 70 °C — a curve you'll want to check if the panel sits near a hot motor or a sunny wall.
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — that 86 mm depth is the dimension to watch when you're sliding it into a tight enclosure or a panel with a shallow backpan. It's a 3-pole unit rated for 800 V insulation voltage, so it fits standard 3-phase distribution panels up to 690 V line-to-line.
