Its 3-pole construction and ETU550 electronic trip unit make it a line-protection breaker with communication capability, suited for main or feeder duty in distribution panels where you need adjustable protection curves and remote monitoring. This MCCB delivers 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. For 400 V-class panels (the common industrial distribution voltage), the 242 kA interrupting rating covers virtually any utility transformer size you'll encounter. The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a 3-pole MCCB footprint that fits standard Siemens 3VA switchboard and panelboard mounting. ## Trip unit and communication The communication function enables integration with energy management systems or PLCs via the 3VA communication modules, allowing remote trip indication, current metering, and parameter adjustment. No undervoltage release, voltage trigger, or trip indicator is fitted from the factory; those are field-addable accessories if your application requires them.","metaTitle":"Siemens 3VA2040-7JP32-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU55","metaDescription":"Siemens 3VA2040-7JP32-0AA0 SENTRON molded case circuit breaker, 40 A rated, 3-pole, ETU550 release, 330 kA at 240 V.
