It is designed specifically for motor protection, with built-in phase failure detection that trips the breaker if one phase drops out, preventing single-phasing damage to the motor windings. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V — so it handles high-fault-current scenarios at common low-voltage distribution levels, with the 690 V figure being the practical ceiling for this frame size. The 110 mm depth leaves clearance for rear-connected busbars or cable ladders behind the mounting plate. Maximum power loss is 37.5 W at rated load — relevant for enclosure thermal calculations if you are packing multiple breakers in a sealed cabinet.","metaTitle":"Siemens SENTRON 3VA2325-5MN32-0AD0 MCCB, 250 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2325-5MN32-0AD0 molded case circuit breaker, 250 A, 3-pole, 187 kA breaking capacity at 240 V.
