It does not have a Trip Indicator or Undervoltage Release. The ground-fault monitoring version uses summation current formation on the L + N conductor — it monitors the vector sum of phase and neutral currents, so it catches leakage to ground without a separate sensor. A Communication Function is present, which means it can report status or trip events over a bus — useful for a monitored distribution panel. ## Mounting dimensions and panel fit If you are swapping into an existing panel that was built around that alternate MPN, the mounting hole pattern and bus connection points are the same.","metaTitle":"Siemens 3VA2163-5JQ46-0AA0 SENTRON MCCB, 63 A, 4-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2163-5JQ46-0AA0 molded case circuit breaker, 63 A rated, 4-pole, line protection.
