This is a line-protection device — not a motor-protective breaker — so it is sized for feeder and distribution duty where selectivity and fault coordination drive the spec. The ETU850 brings communication capability, meaning it can report trip events and load data over the integrated bus interface, which matters if you are building a panel that needs energy monitoring or remote diagnostics without an add-on module. Breaking capacity is the headline: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 6.3 kA at 690 V. Thermal derating is published across the operating range: the breaker carries 250 A continuously at ambient temperatures up to 50 °C, then derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. The breaker ships with 4 auxiliary switches (HQ type) pre-installed. No undervoltage release or shunt trip is fitted from the factory — those are field-installable accessories if your safety circuit requires a UVR. Maximum power dissipation is 48 W at rated current. ## What the ETU850 trip unit enables The operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C — suitable for unheated warehouses or outdoor enclosures as long as the IP40 front is protected.","metaTitle":"Siemens 3VA2225-7KP32-0AE0 SENTRON MCCB, 250 A, ETU850, 3-Po","metaDescription":"Siemens 3VA2225-7KP32-0AE0 SENTRON molded case circuit breaker, 250 A rated continuous current, 3-pole, ETU850 electronic trip unit, 330 kA at 240 V.

The key difference is the trip unit: the -7KP32-0AE0 carries an ETU850 (electronic, communication-capable), while the -5JQ32-0AK0 uses a different trip variant.
