The Siemens 5SY45 is a 3-pole miniature circuit breaker (MCB) from the Sentron series, designed for reliable protection of circuits against overload and short-circuits. Rated at 32 amps, 400 VAC, with a 10 kA breaking capacity, this breaker uses a B-curve trip characteristic, making it ideal for resistive and low inrush current loads. Compact DIN-rail mounting allows easy installation in industrial control panels, distribution boards, and equipment protection applications.
