1-pole protection 10kA breaking capacity B-curve characteristic For low inrush circuits Compact 70mm depth Siemens quality

Product description

The Siemens 5SY4106-6 is a reliable 1-pole miniature circuit breaker designed for general electrical protection. It offers a 10kA breaking capacity at 230/400V and features a B-curve tripping characteristic, suitable for circuits with low inrush currents. This unit is rated at 6A and has a standard 70mm installation depth.

The B-curve is the most common type for residential and light commercial applications, designed to trip between 3 to 5 times the rated current. It's ideal for protecting resistive loads like lighting and heating elements, as well as sensitive electronic equipment where minimal surge is expected. This makes it a versatile choice for general distribution boards.

Stanlo Automation, a veteran-owned supplier of industrial surplus parts, ensures you receive quality components like the Siemens 5SY4106-6. We are committed to providing reliable and cost-effective solutions to keep your automation systems running smoothly.
