The SIEMENS 5SY4106-8 is a 1-pole miniature circuit breaker (MCB) rated for 230/400 V with a 6 A D-characteristic and 10 kA breaking capacity, designed to protect single-phase circuits. Its D tripping curve provides reliable protection for installations with moderate inrush currents, such as motors or transformer-fed loads, while limiting fault currents up to 10 kA. With a 70 mm device depth, it fits standard panel installations and simplifies wiring layout. Use this MCB to secure lighting, distribution branches, or equipment circuits where controlled delayed tripping for short surges is required.
