Interrupting capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 500 V — figures that cover most North American and European low-voltage fault levels. The part carries IP40 on the front face — splash-protected in the panel but not rated for washdown zones. Mounting is via the rear panel or DIN rail adapter plate (not included). Verify the busbar or lug kit separately — the breaker ships without terminals. The ETU320 trip unit draws its power from the line-side current, no auxiliary supply needed.","metaTitle":"3VA2225-4HL42-0AA0 SENTRON MCCB, 250 A, 4-Pole, ETU320, 121","metaDescription":"SENTRON 3VA2225-4HL42-0AA0 molded case circuit breaker, 250 A continuous, 4 poles, ETU320 release.
