The Siemens SENTRON 3VA2116-5HN32-0DH0 is a 3-pole molded case circuit breaker rated for 160 A continuous current at up to 70 °C ambient — no derating needed across the full operating temperature band. That 160 A holds at every point from 40 °C through 70 °C, so it nails the cure recipe in a hot press room without a temperature-compensation table. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That gives real selectivity headroom downstream — the 121 kA at 415 V means it can ride through a bolted fault on a 2 MVA transformer secondary without upstream coordination issues.
Line protection with undervoltage release
The supplied basic switch is order code 3VA21165HN320AA0, which means the internal switching mechanism is a known, replaceable subassembly. No communication function or ground-fault monitoring on this variant — it is a straight thermal-magnetic line protection breaker with the UVR add-on.
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA frame size that mounts on a DIN rail or directly to a backplate. The 86 mm depth leaves room for rear-connected busbars in a typical MCC bucket.
