160 A MCCB with 242 kA interrupting rating
The SENTRON 3VA2116-6HN32-0JA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current, designed for line protection in distribution panels. Its interrupting capacity hits 242 kA at 240 V — that's the short-circuit current it can safely clear without welding or rupturing, critical for high-fault installations like transformer secondaries or large motor control centers. The 187 kA rating at 415 V and 440 V still covers most industrial service entrances. At 690 V the rating drops to 3.7 kA, so verify the available fault current if you're feeding a 690 V bus. The 160 A rating holds flat from 40 °C through 70 °C ambient — no derating needed in a warm enclosure. 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.
Panel fit and integration
Dimensions are 86 mm deep, 105 mm wide, 181 mm tall. 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. Verify the gland plate opening if you're retrofitting into an existing panel — the 86 mm depth leaves room for rear-connected busbars.
