The 320 mm height, 210 mm width, and 120 mm depth fit standard 3-pole MCCB panel cutouts; front IP40 protection suits enclosed distribution boards. ## Thermal derating and continuous current Above that the unit derates linearly: 955 A at 60 °C, 885 A at 65 °C, and 815 A at 70 °C. For a panel builder or site engineer, this means the breaker can be loaded to its nameplate in a ventilated 55 °C enclosure; above that, the trip unit's thermal memory adjusts the protection curve accordingly. The adjustable long-time delay tr spans 0.5 s to 25 s, and short-time delay tsd ranges 0.05 s to 0.5 s — giving selectivity coordination flexibility downstream. ## Communication and monitoring The breaker includes a communication function and an other measurement function, which on the ETU860 platform typically enables power metering, alarm forwarding, and remote trip indication over a bus system (PROFIBUS or PROFINET via a communication module). The N-conductor protection is not fitted; this unit is for 3-wire line protection. ## Environmental and endurance ratings","metaTitle":"Siemens 3VA2510-5KQ32-0HA0 SENTRON MCCB, 1000 A, 3-Pole, Lin","metaDescription":"Siemens 3VA2510-5KQ32-0HA0 SENTRON molded case circuit breaker, 1000 A rated continuous current, 3-pole, line protection, 187 kA at 240 V.
