It is a line protection version, meaning it is configured for feeder or main breaker duty rather than motor protection. The 1000 A rating holds flat through 55 °C, then derates to 955 A at 60 °C, 885 A at 65 °C, 815 A at 70 °C — useful when the breaker sits in a warm enclosure or near other heat sources. Breaking capacity is substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 73.5 kA at 690 V. These figures cover most industrial fault-current scenarios, including high-capacity transformer secondaries and large motor banks. The ETU320 trip unit provides adjustable N-conductor protection (OFF, 50%, 100% of phase rating) — a feature for systems where neutral protection must be coordinated with phase protection. For buyers managing a BOM freeze or PCN watch, this part is not subject to a last-time-buy or phase-out notice. The SENTRON 3VA platform is Siemens' current-generation MCCB family, widely specified in new panel designs and retrofit projects. No official successor exists because none is needed. ## Panel Integration & Physical Fit Dimensions are 320 mm height × 280 mm width × 120 mm depth. The 280 mm width across 4 poles means each pole occupies roughly 70 mm — standard for a 1000 A frame. Panel cutout and mounting hole pattern follow the SENTRON 3VA footprint; verify against existing busbar or cable lug centers before committing the layout. Maximum power loss is 330 W at rated current, so forced ventilation or derating may be needed in a sealed, high-density cabinet. The 70 °C operating ceiling matches the top of the derating curve — the breaker can run at 815 A at that limit, not the full 1000 A. ## Comparison with 3VA2110-7HK42-0AA0 The closest functional peer is the 3VA2110-7HK42-0AA0. Both are 4-pole SENTRON MCCBs with 1000 A frames. The key difference is the trip unit: the 3VA2510-6HL42-0AA0 carries the ETU320 electronic release (adjustable N-protection, no communication), while the 3VA2110-7HK42-0AA0 uses a different trip unit variant. Panel cutout and busbar centers are identical — a panel laid out for one will accept the other without rewiring, provided the trip curve and auxiliary requirements match the application.","metaTitle":"Siemens 3VA2510-6HL42-0AA0 SENTRON MCCB, 1000 A, 4-Pole, ETU","metaDescription":"Siemens SENTRON 3VA2510-6HL42-0AA0 molded case circuit breaker, 1000 A rated, 4-pole, ETU320 trip unit.
