Siemens SENTRON 3VA2216-7MN32-0CH0 — 160 A MCCB, Motor Protection, ETU350M
The Siemens SENTRON 3VA2216-7MN32-0CH0 is a 3-pole molded case circuit breaker rated for 160 A continuous current at 40 °C, built around the ETU350M electronic trip unit for motor protection duties. Its breaking capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V — figures that cover high-fault installations like large motor control centers or transformer secondaries.
Ratings and Thermal Derating
Above that, derating applies: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. For a panel running warm — say, near a drive cabinet — the 60 °C figure is the one to budget against. The storage floor matters if this sits as a critical spare in an unheated warehouse.
Depth of 86 mm leaves clearance for rear-connected busbars or cable lugs. Latching endurance is rated at 20,000 operations.
