It carries an ETU320 electronic trip unit with adjustable N-conductor protection (OFF or 100%). Breaking capacity is the headline: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, 53 kA at 690 V. The 4-pole version handles three-phase plus neutral, with the neutral pole configurable for no protection or full protection. Front IP40 protection means it's suited for dry indoor panels; no washdown rating. The ETU320 trip unit is field-adjustable for long-time delay (tr min 0.5 s to tr max 17 s) and other parameters, so it can be tuned to coordinate with downstream breakers without swapping the unit.","metaTitle":"Siemens 3VA2125-8HL46-0AA0 SENTRON MCCB, 4-pole, 25 A, 440 k","metaDescription":"Siemens SENTRON 3VA2125-8HL46-0AA0 molded case circuit breaker, 4-pole, 25 A rated continuous current, 440 kA breaking at 240 V.
