The interrupting ratings climb to 330 kA at 240 V, 242 kA at 415 V and 440 V, and 187 kA at 500 V — numbers that place it in the high-fault-current class, suited for main or feeder positions where available fault current is substantial. At 690 V it still clears 3.7 kA. ## Trip unit and protection logic It uses the ETU550 electronic trip unit, which supports adjustable N-conductor protection (OFF, 40 % to 160 % of the phase setting) — useful for panels feeding unbalanced loads or where the neutral conductor needs its own pickup curve. Listed as current production. ## Communication and auxiliary options The breaker includes a communication function — the ETU550 can interface with the SENTRON powerconfig software and support Modbus or PROFIBUS via a communication module, giving visibility into load current and trip events without a separate power meter.","metaTitle":"Siemens 3VA2140-7JP32-0AA0 MCCB, 40 A, 3-Pole, ETU550, 330 k","metaDescription":"Siemens SENTRON 3VA2140-7JP32-0AA0 molded case circuit breaker, 40 A, 3-pole, ETU550 trip unit, 330 kA at 240 V.
