The Siemens SENTRON 3VA2163-5MN36-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current, with a motor protection designation and an ETU350M electronic trip unit. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V — so it handles high-fault panels without cascading upstream breakers. The built-in undervoltage release and phase failure detection make it a fit for motor branch circuits where loss-of-phase or undervoltage conditions need automatic disconnection.
The 3VA2163-5MN36-0DA0 measures 86 mm deep, 105 mm wide, and 181 mm tall — a standard SENTRON 3VA frame that mounts directly onto a DIN rail or panel-mount adapter. The ETU350M release is field-configurable for overload and short-circuit thresholds, and the undervoltage release (UVR) coil draws from the control circuit. Maximum power dissipation is 75 W, so factor that into enclosure thermal calculations. The operating range spans -25 °C to 70 °C, with a 63 A rating holding steady up to 50 °C; above that it derates to 56.7 A at 70 °C.
