The line-protection design means it's tuned for cable and busbar protection, not motor overload curves. Current-production part (lifecycle stage: current). Includes undervoltage release (UVR) and 2+1+1 auxiliary switch configuration. Communication function onboard. ## Sizing and selectivity realities At 100 A continuous and 187 kA SCCR at 240 V, this breaker sits in the middle of the 3VA2 frame range (adjustable from 150 A minimum to 1 200 A maximum). The 105 mm width (4.13 in) and 86 mm depth (3.39 in) mean it fits standard panel-mount cutouts for SENTRON MCCBs — no special adapters. The 16 W max power loss is modest for this class, so thermal rise in a crowded enclosure stays manageable. Compared to the 3VA1110-5EF32-0AM0, which is a 3-pole 100 A frame with a lower 25 kA interrupting at 415 V, this 3VA2010 carries substantially more fault-current headroom (121 kA at 415 V). If your panel SCCR requirement exceeds 25 kA, this is the correct drop-in — same footprint family, same mounting pattern, but rated for higher-energy distribution points. ## What's on board: releases and auxiliaries The auxiliary switch block gives you two form-C (changeover) aux contacts, one trip-alarm contact that changes state only on a fault trip, and one electrical alarm contact for remote indication. All wired to the terminal block, no extra assembly required. A communication function is onboard, so the breaker can report status and trip events to a higher-level monitoring system — useful for plant-floor dashboards or predictive maintenance triggers. The basic switch inside is part number 3VA20105KP320AA0, which is the internal mechanism; the complete unit ships as the 3VA2010-5KP32-0BL0 order code. The 100 A rating holds across the full operating range — no derating curve to calculate for hot panels.","metaTitle":"Siemens 3VA2010-5KP32-0BL0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2010-5KP32-0BL0 molded case circuit breaker, 100 A continuous, 3-pole, 187 kA at 240 V.
