The 4-pole frame and ETU550 electronic trip unit give you adjustable long-time delay (0.5 to 25 s) and N-conductor protection configurable from OFF to 160 % of the phase setting, which matters when coordinating selectivity on a 4-wire distribution bus. The 330 kA rating at 415 V and 440 V covers common industrial distribution voltages across Europe and Asia; the 220 kA at 500 V suits Canadian 480Y/277 V panels. These figures are the SCCR the breaker itself can clear — the panel's overall SCCR still depends on the weakest component in the feeder. The ETU550 is an electronic trip unit with adjustable long-time pickup and delay (tr min. 0.5 s, tr max. 25 s), plus the N-conductor protection can be set to OFF or between 40 % and 160 % of the phase current setting. That adjustability lets you tune the breaker to the actual cable and load without swapping trip packs.","metaTitle":"Siemens 3VA2125-8JP46-0AA0 SENTRON MCCB, 25 A, 4-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2125-8JP46-0AA0 molded case circuit breaker, 25 A rated continuous current, 4-pole, ETU550 electronic trip unit, 440 kA SCCR at 240 V.
