Siemens 5SY4210-5 Miniature Circuit Breaker — 2-Pole, A-Curve, 10A

The Siemens 5SY4210-5 is a two-pole miniature circuit breaker offering highly sensitive overcurrent protection. It features an A-curve tripping characteristic, a 400V rated voltage, and a 10kA short-circuit breaking capacity. With a 10A current rating and a standard 70mm width (D=70 mm), it is suitable for specialized applications requiring fast response to overloads.

This circuit breaker is typically used for protecting sensitive electronic equipment, control circuits, and semiconductor devices where rapid detection of even small overcurrents is critical. The A-curve trips between 1 to 3 times the rated current, providing precise protection.
