The Siemens 3VA2563-5MN32-0JH0 is a 3VA2 IEC frame 1000 circuit breaker with a 55 kA breaking capacity at 415 V, 3-pole, designed for motor protection. It carries an ETU350M LSI electronic trip unit, with a 630 A frame rating (In) and overload protection adjustable from 250 A to 630 A (Ir). Short-circuit protection (Isd) is set from 3 to 15 times Ir, and instantaneous protection (Ii) is fixed at 15 times In. A nut keeper kit is also included for secure mounting.
The ETU350M LSI trip unit provides adjustable overload (Ir) and short-time (Isd) protection, letting you dial in the curve for motor starting inrush without nuisance tripping. The shunt trip (STL) at 110-127 V DC/AC allows remote tripping from a safety circuit or emergency stop—common in automated lines where a technician needs to kill power from a panel door.
Installation notes
The 3-pole design fits a 3-phase motor branch circuit. Verify the shunt trip coil voltage matches your control voltage before wiring; the 110-127 V range covers common industrial control transformers.
