Description
About the Product
The Lauritz Knudsen CM90631OOMO from the DU250C series is a high-performance 3 Pole Moulded Case Circuit Breaker (MCCB) engineered to provide reliable circuit protection, efficient fault interruption, & cost-effective performance for industrial, commercial, & infrastructure electrical systems. Rated at 160A & 415V AC, this MCCB safeguards electrical circuits, equipment, & power distribution networks against overloads & short-circuit faults while ensuring dependable operation under demanding load conditions.
The breaker incorporates an advanced thermal-magnetic trip mechanism that delivers dual-layer protection against electrical abnormalities. The thermal protection element provides time-delayed tripping during overload conditions, preventing overheating & protecting cables, conductors, & connected equipment from damage caused by prolonged overcurrent. The magnetic protection element responds instantaneously to short-circuit faults, rapidly isolating the affected circuit to minimize system damage & maintain operational safety.
With a breaking capacity of 25kA, the DU250C MCCB offers a balanced level of fault interruption capability that positions it between standard-duty & high-performance MCCBs. This makes it an excellent choice for installations requiring enhanced protection against moderate to high fault currents without the additional cost associated with higher-capacity breakers. The 25kA rating ensures safe interruption of fault currents while improving system reliability & equipment protection.
The 3 Pole configuration is specifically designed for three-phase electrical systems commonly found in industrial machinery, commercial facilities, utility installations, & power distribution networks. Operating at 50/60 Hz, the breaker is fully compatible with standard electrical systems across various applications.
Constructed with a rugged industrial-grade housing & precision-engineered internal components, the DU250C series delivers excellent mechanical durability, dependable switching performance, & long operational life. Its robust design ensures reliable operation in challenging environments while maintaining consistent protection performance.
The compact construction enables easy integration into switchgear assemblies, distribution boards, control panels, & motor control centers (MCCs), helping optimize space utilization while simplifying installation & maintenance activities.
This 160A MCCB is an ideal solution for applications requiring mid-range fault protection, dependable operation, enhanced safety, & an effective balance between performance & affordability.
