SIEMENS 5SY6325-7 installatieautomaat C25A 3-polig 6kA 400V AC

The SIEMENS 5SY6325-7 is a 3-pole miniature circuit breaker (MCB) with a rated current of 25 A and C tripping characteristic, providing reliable protection against overloads and short circuits in AC installations. Its 6 kA breaking capacity ensures safe interruption of fault currents up to 6,000 A.

Advantages

This MCB offers precise protection with a C-curve, making it ideal for circuits with moderate inrush currents. The 3-pole design enables simultaneous disconnection of all phases, enhancing safety in three-phase systems. With a compact 3-module width (54 mm), it optimizes space on DIN rails.

Suitable for

• Three-phase distribution boards in residential and commercial buildings
