At 690 V the interrupting rating drops to 4.5 kA — the high short-circuit performance is concentrated at the lower distribution voltages where most industrial service-entrance and feeder applications sit. The breaker carries a thermal derating curve: it holds 250 A through 50 °C, then steps down to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. That means in a warm panel or enclosure with limited airflow, the effective continuous current is lower than the nameplate — size your load and ambient together. ## Built for selectivity and coordination in distribution panels A communication function is onboard, and a voltage trigger is present for undervoltage or overvoltage detection (though no undervoltage release is fitted as standard). The 86 mm depth, 105 mm width, and 181 mm height fit standard SENTRON mounting footprints; verify the back-panel cutout and bus-bar spacing against the existing panel layout. ## Environmental and operating range Maximum power loss is 48 W at rated load. The breaker includes a mechanical trip indicator for visual fault confirmation. The basic switch supplied is order code 3VA2225-5JP32-0AA0.","metaTitle":"Siemens 3VA2225-5JP32-0KH0 SENTRON MCCB, 250 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5JP32-0KH0 molded case circuit breaker, 250 A continuous at 40 °C, 3-pole, 187 kA breaking at 240 V.
