Siemens SENTRON 3VA2163-5MN36-0CH0 — Motor Protection MCCB, 63 A, 3-Pole
It carries a 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the steep fall at 690 V means this breaker is best applied in 240–500 V systems where its high interrupting rating delivers real selectivity headroom. Built into the SENTRON platform, this MCCB includes an undervoltage release and phase failure detection as standard — two features that matter for motor circuits: the UVR drops the breaker if control voltage dips below the dropout threshold, and phase-loss detection prevents single-phasing damage on a three-phase motor.
