The Siemens 3VA2116-6HL46-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current in a 4-pole configuration, with an ETU320 electronic trip unit for line protection. Its interrupting capacity reaches 242 kA at 240 V, dropping to 187 kA at 415 V and 440 V, and 121 kA at 500 V — at 690 V it still holds 3.7 kA. That SCCR headroom means it can sit upstream in a high-fault panel without cascading to the main breaker, a real advantage when coordinating selectivity in a 400 V industrial distribution board.
The breaker measures 86 mm deep, 140 mm wide, and 181 mm high — a standard SENTRON 3VA2 footprint that fits existing panel cutouts and DIN-rail or screw-mount backplates. Front-side IP40 protection keeps dust out of the enclosure; the rear terminals accept busbar or cable connections typical of a 160 A MCCB. No undervoltage release or communication module is fitted on this variant, so it is a straightforward thermal-magnetic replacement in a line-protection role.
