Breaking capacity is the headline selector here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. ## Thermal performance and ground-fault monitoring Power loss is 4 W maximum, low enough to ignore in thermal busbar calculations for most panel layouts. Ground-fault monitoring uses summation current formation on the L + N conductors, meaning it measures vector sum of phase and neutral currents to detect leakage. This is a residual-current detection method built into the breaker, not an add-on module — simplifies wiring in TN and TT systems where neutral must pass through the sensor.","metaTitle":"Siemens 3VA2163-7HM42-0AA0 SENTRON MCCB, 63 A, 4-Pole, 330 k","metaDescription":"Siemens 3VA2163-7HM42-0AA0 SENTRON molded case circuit breaker, 63 A continuous, 4-pole, line protection.

The 3VA2163-7HM42-0AA0 uses a specific trip characteristic and ground-fault monitoring (summation current L+N) that the 8HM32 variant may not share. Verify the trip unit and accessory set before substituting — the mechanical footprint is the same, but the protection profile differs."},{"question":"Will 3VA2163-7HM42-0AA0 drop into a panel that was specified around 3VA2163-8HM32-0AA0 without rewiring?","answer":"The mechanical dimensions (86 mm depth, 140 mm width, 181 mm height) are identical across the 3VA2 frame family, so the physical fit is the same. However, the 7HM42 variant includes ground-fault monitoring via summation current formation on L+N, which the 8HM32 may not have. If the original panel wiring expects that ground-fault function, the 7HM42 will work; if not, the additional monitoring is simply unused. No rewiring is required for the basic line protection function."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2163-7HM42-0AA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA2163-7HM42-0AA0 when reusing this data.
