What the ratings mean for fit
The 3VA2116-5HL32-0AE0 is a SENTRON molded case circuit breaker rated for 160 A continuous current at 40 °C, with an ETU320 electronic trip unit for line protection. The 187 kA breaking capacity at 240 V and 121 kA at 415 V mean it can safely interrupt high-fault currents in a main distribution panel without upstream fuses needing to clear first — that's the kind of SCCR headroom that simplifies coordination studies. The 3-pole design covers three-phase loads; the IP40 front protection keeps dust out of the enclosure face but expects a clean, dry panel environment.
Thermal derating and operating range
The 160 A rating holds flat from 40 °C to 50 °C, then derates linearly to 136 A at 70 °C. If the panel ambient runs hot — say near a row of drives — the 154 A at 55 °C or 148 A at 60 °C figures are the ones to plan against, not the 160 A headline. Operating temperature spans -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Dimensions and panel fit
At 181 mm high, 105 mm wide, and 86 mm deep, this MCCB fits standard SENTRON 3VA mounting footprints. The 105 mm width is three-pole wide — verify the DIN-rail or screw-mount spacing in the existing panel before ordering. The 86 mm depth leaves clearance for rear busbar connections or auxiliary contact wiring.
