The interrupting capacity tops out at 330 kA at 240 V AC, stepping down to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V — these SCCR figures govern where this breaker can be applied without cascading upstream protection. The ETU550 electronic trip unit provides adjustable long-time delay (tr) from 0.5 s to 25 s and adjustable N-conductor protection (OFF, 40%, 160%). ## SCCR and Selectivity Coordination The ETU550 release supports full selectivity with downstream breakers via the adjustable tr and I²t curves. Front IP40 protection covers the operator interface; the ETU550 includes communication functionality for integration into higher-level monitoring systems. The 4-pole construction with adjustable N-conductor protection makes it suitable for 3-phase + neutral distribution where neutral protection must be configured per the system grounding scheme.","metaTitle":"Siemens 3VA2040-7JP46-0AA0 SENTRON MCCB, 4-Pole, 40 A, ETU55","metaDescription":"Siemens 3VA2040-7JP46-0AA0 SENTRON molded case circuit breaker, 4-pole, 40 A continuous, ETU550 electronic trip unit, 330 kA interrupting at 240 V.
