The interrupting capacity reaches 187 kA at 240 V (cite:), 121 kA at 415/440 V (cite:,), 75.6 kA at 500 V (cite:), and 7.5 kA at 690 V (cite:) — so it handles high-fault scenarios at common low-voltage levels while the 690 V figure confirms it can clear faults on 690 V drives or transformer secondaries, though the margin is tighter. ## Thermal performance — no derating surprises That flat thermal curve is unusual — most MCCBs start derating above 40 °C. No undervoltage release (cite:) and no voltage-triggered trip (cite:); protection is purely thermal-magnetic with line-protection curve (cite:). Ground-fault monitoring uses summation-current formation on the L-conductor (cite:). Communication function is equipped (cite:), so it can integrate with a BMS or energy-management system via the SENTRON communication modules.","metaTitle":"Siemens 3VA2325-5JQ32-0AA0 SENTRON MCCB, 250 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2325-5JQ32-0AA0 molded case circuit breaker, 250 A continuous, 3-pole, line protection.
