Product details

SENTRON 3VA2025-5KP36-0AA0 — 25 A MCCB with ETU850 Trip Unit

The Siemens 3VA2025-5KP36-0AA0 is a SENTRON series molded case circuit breaker (MCCB) rated for 25 A continuous current on a 3-pole frame, fitted with the ETU850 electronic trip unit. The breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — covering most low-voltage fault scenarios in industrial and commercial installations.

Physical Fit and Mounting

The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — standard for a 3VA2 frame. Verify the panel cutout and busbar spacing against these dimensions before ordering; the 105 mm width is the same as other 3VA2 3-pole units, so a panel laid out for a sibling like the 3VA2125-8KQ42-0AA0 should accept this one without rewiring — same frame, same footprint.

Frequently asked questions

Where can I buy 3VA2025-5KP36-0AA0 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time.

What is the breaking capacity of 3VA2025-5KP36-0AA0 at different voltages?

187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. The steep drop at 690 V is typical for this frame size — verify your system's available fault current at that voltage.

Will 3VA2025-5KP36-0AA0 drop into a panel specified for 3VA2125-8KQ42-0AA0?

Yes — both are 3-pole 3VA2 frame units with the same 105 mm width, 181 mm height, and 86 mm depth. The panel cutout and busbar spacing are identical; no rewiring needed for the physical fit. The difference is in the trip unit and rating, so verify the protection settings match your load.
