Hager NDN350 MCB 3P D-50A 10kA 3M

The Hager NDN350 is a high-performance miniature circuit breaker (MCB) designed for three-phase electrical systems. With a rated current of 50A and a D tripping curve, it is ideal for protecting circuits with high inrush currents, such as motors and transformers. The breaker offers a breaking capacity of 10kA (15kA according to some standards), ensuring robust fault interruption.

• 3-pole design for three-phase applications (400V)
• D-curve trip characteristic for inductive loads
• 50A rated current for medium to high-power circuits
• 10kA breaking capacity (also rated 15kA per IEC 60898-1)
• 3 module width for standard DIN rail mounting

This MCB is suitable for use in distribution boards and industrial panels where reliable overcurrent and short-circuit protection is required. Always consult local regulations and ensure proper installation by a qualified electrician.
