160 A MCCB with 242 kA interrupting rating
That's unusual for an MCCB; most need a haircut above 40 °C. The shunt trip release (STL) lets you remotely open the breaker via a control signal, which is standard for emergency-stop circuits or interlocking schemes. No undervoltage release on this variant, so if you need UVR for a safety circuit, this isn't the one.
The 105 mm width for a 3-pole 160 A frame is standard for SENTRON 3VA2 breakers — it occupies three 35 mm DIN spaces plus a bit of side clearance. Mounts on DIN rail or direct panel; the shunt trip adds a pair of control terminals.
