What it is and what it does
The Siemens SENTRON 3VA2325-6HL32-0AB0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current, designed for line protection in distribution panels. It holds its full 250 A rating across the entire 40 °C to 70 °C ambient range with no derating — a practical advantage when the breaker sits in a warm enclosure next to other heat sources. Breaking capacity is the headline: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, dropping to 7.5 kA at 690 V. That 242 kA figure at 240 V means it can safely interrupt a fault current up to that level without cascading upstream — critical for high-available-fault-current installations like large transformer secondaries or industrial service entrances. Physical footprint: 110 mm deep, 138 mm wide, 248 mm tall. Maximum power loss is 37.5 W — factor that into enclosure thermal calculations if you're packing several breakers in a confined panel.
Configuration and auxiliary options
This variant ships without a trip indicator, undervoltage release, communication module, ground-fault monitoring, or auxiliary release. It includes 2 auxiliary switches (HP design). The basic switch supplied is order code 3VA2325-6HL32-0AA0. It is configured for line protection only — no voltage trigger, no other measurement function.
