The breaker includes a ground-fault monitoring function using summation current formation on the L-conductor, which detects leakage without a separate core-balance transformer. ## Interrupting capacity across voltage levels This MCCB's interrupting capacity is not a single number — it varies with system voltage. At 240 V it clears 242 kA; at 415 V and 440 V it holds at 187 kA; at 500 V it drops to 121 kA; and at 690 V it is rated 3 kA. The 63 A continuous rating is derated across the full temperature range from 40 °C to 70 °C without reduction — the same 63 A holds at 70 °C, which is unusual and simplifies panel sizing in warm environments. ## Panel fit and mounting dimensions The breaker measures 86 mm depth, 105 mm width, and 181 mm height. The 86 mm depth leaves clearance for rear-connected busbars or a cable duct behind the mounting plane. ## Communication and monitoring capability This variant includes a communication function and an other measurement function, which typically means it can interface with a bus system (PROFIBUS or PROFINET via a communication module) for remote trip indication, current metering, and parameterization. The ground-fault monitoring version uses summation current formation on the L-conductor, so it detects residual currents without a separate neutral CT — useful on 3-phase loads where a neutral is not run. No undervoltage release or trip indicator is fitted on this order code; those are separate accessories.","metaTitle":"Siemens 3VA2063-6KQ36-0AA0 SENTRON MCCB, 63 A, 242 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-6KQ36-0AA0 molded case circuit breaker, 63 A continuous, 242 kA interrupting at 240 V.

The 6KQ36 variant includes ground-fault monitoring and communication; the 8JQ32 does not. Wiring to the line and load terminals is the same, but the control wiring for the additional functions differs. No rewiring of the power circuit is needed."},{"question":"What is the interrupting capacity of this MCCB at 415 V?","answer":"At 415 V the interrupting capacity is 187 kA.
