Siemens 5SX2 310-8 is a three-pole circuit breaker from the 5SX2 family, designed to protect three‑phase circuits in industrial and commercial electrical panels. The 310-8 variant is rated for 13 A per pole and offers a short‑circuit breaking capacity up to 6 kA, providing reliable protection for loads against overloads and faults in multi‑phase distributions. This model sits within a broader 5SX2 line that covers three‑pole configurations across a current range from 0.5 A up to 40 A, making it suitable for applications such as motor protection and general three‑phase distribution in control panels and equipment enclosures.
