The ETU550 electronic trip unit manages overload and short-circuit curves, and the breaker communicates via an integrated communication function, so it reports status and trip events back to a PLC or BMS without an add-on module. At 415 V and 440 V the breaker still clears 121 kA — that covers most industrial distribution panels fed from a 500 kVA to 2 MVA transformer where the prospective fault current at the main switchboard lands in the 50–100 kA range. At 500 V it drops to 75.6 kA, and at 690 V it falls to 3.7 kA, so for 690 V drives or mining gear the breaker is only suitable downstream of a current-limiting device. The front protection is IP40.","metaTitle":"Siemens 3VA2140-5JP32-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2140-5JP32-0AA0 molded case circuit breaker, 40 A, 3-pole, ETU550 release, 187 kA at 240 V.
