The 187 kA interrupting rating at 240 VAC and 121 kA at 415/440 VAC give it the headroom to clear high-fault conditions without upstream coordination issues, which keeps a weld line or conveyor string from cascading into a plant-wide blackout when a downstream fault occurs. Above that, the ETU550 derates linearly: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. If this MCCB sits in a non-ventilated enclosure near other heat sources — common in a packed automotive panel — the 55 °C column is the realistic planning number. The 86 mm depth includes the arc-chamber housing; verify clearance to the gland plate or enclosure door if rear-access bus bars are used. ## Communication and trip-unit capability The breaker does not include an undervoltage release or shunt trip as standard; those are add-on accessories. The insulation voltage rating of 800 V means it is suitable for 690 VAC systems where the 4.5 kA interrupting rating at 690 V applies — that is a niche application, but the breaker is rated for it.","metaTitle":"Siemens 3VA2225-5JP32-0AA0 SENTRON MCCB, 250 A, 3-Pole, ETU5","metaDescription":"Siemens 3VA2225-5JP32-0AA0 SENTRON molded case circuit breaker, 250 A continuous, 3-pole, ETU550 electronic trip unit.

For a typical 480 V system, the 121 kA at 440 V figure is the closest published rating; the 75.6 kA at 500 V provides a conservative lower bound."},{"question":"Will 3VA2225-5JP32-0AA0 drop into a panel specified for 3VA2225-5JQ32-0AK0?","answer":"Both share the same 3VA2 frame size and 105 mm width, so the physical footprint is identical. The 5JP32-0AA0 uses the ETU550 trip unit, while the 5JQ32-0AK0 uses a different trip unit variant. The mounting hole pattern and bus-bar connections are the same, so it will fit without rewiring, but the trip-unit programming and communication interface may differ — verify the protection curve settings match your coordination study."},{"question":"Where can I buy 3VA2225-5JP32-0AA0?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
