Siemens SENTRON 3VA2225-7HL32-0AH0 — 250 A MCCB for Line Protection
The Siemens SENTRON 3VA2225-7HL32-0AH0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current, designed specifically for line protection in distribution panels and industrial switchboards. Its interrupting capacity varies sharply with system voltage: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V — the 690 V figure is a low-fault condition, not a general-purpose rating at that voltage. Thermal derating is minimal up to 50 °C (full 250 A), then drops to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C — relevant for high-ambient enclosures or tight panel layouts. The breaker ships with a factory-fitted basic switch (order code 3VA2225-7HL32-0AA0) and includes 2 auxiliary switches plus 1 trip alarm switch (HQ design). No undervoltage release, no ground-fault monitoring, no communication module are included — those are field-addable options if needed.
Lifecycle & Sourcing
The 3VA series is the current-generation MCCB platform from Siemens, replacing earlier SENTRON 3VL and 3VF families. No direct form-fit-function substitute from a different manufacturer is listed in the official documentation.
Panel Integration & Dimensions
Dimensions are 86 mm depth, 105 mm width, 181 mm height — fits standard MCCB mounting footprints in distribution boards and motor control centers. The 3-pole body occupies a single unit width in most panel schedules. Maximum power loss is 48 W at rated current — account for this in thermal calculations for sealed enclosures or high-density panel layouts. Operating temperature range is -25 °C to +70 °C; storage range is -40 °C to +80 °C. The trip indicator is present; no voltage trip or communication function is built in.
