The SIEMENS 5SY6106-8CC is a 1‑pole miniature circuit breaker rated for 230/400 V with a D tripping characteristic and a 6 A current rating. Designed for protection of single-phase circuits, it interrupts fault currents up to 6 kA to help prevent equipment damage and wiring fires. Its D curve makes it suitable for circuits with moderate inrush currents, such as motors or transformer supplies, while the compact form fits standard distribution boards. Installers will appreciate straightforward DIN-rail mounting and clear rating markings for quick identification and consistent circuit protection.
