Design Of The ProductFor transformer protection

Product details

The Siemens 3RV2411-0CA20 is a SIRIUS circuit breaker for transformer protection. Rated at CLASS 10 trip, it clears overloads fast enough to protect the transformer winding from thermal damage during a sustained secondary-side short or inrush event.

Clearance requirements: 50 mm above and below, 30 mm to the side — no extra space needed forward or backward (–,).

Environment and ratings

Temperature compensation is active across the full operating range. Rated operational voltage 20 to 690 V. Maximum switching frequency at AC-3 duty: 15 operations per hour.
