Description
About the Product
The Lauritz Knudsen CM90517OOKO from the DU100D series is a dependable 3 Pole Moulded Case Circuit Breaker (MCCB) designed to provide efficient & economical circuit protection for residential, commercial, & light industrial electrical installations. Rated at 100A & 415V AC, this MCCB safeguards electrical circuits, power distribution systems, & connected equipment against overloads & short-circuit faults while ensuring safe & reliable operation.
The breaker incorporates an advanced thermal-magnetic trip mechanism that delivers dual-layer protection against electrical faults. The thermal protection element provides time-delayed tripping during overload conditions, helping prevent overheating & damage to cables, conductors, & connected electrical equipment caused by sustained overcurrent situations. The magnetic protection element responds instantaneously during short-circuit faults, rapidly isolating the affected circuit & minimizing the risk of electrical damage & operational disruptions.
With a breaking capacity of 18kA, the DU100D MCCB is suitable for installations with low to medium fault levels. This fault interruption capability delivers dependable protection & system stability while providing a cost-effective solution for standard electrical distribution applications where higher fault interruption ratings are not required.
The MCCB is designed for operation on standard 50/60 Hz electrical systems, ensuring compatibility with a wide range of residential, commercial, & light industrial power networks. Its 3 Pole configuration supports three-phase electrical systems commonly found in commercial buildings, apartment complexes, workshops, distribution panels, & light industrial facilities.
Manufactured using durable insulating materials & precision-engineered operating components, the breaker offers reliable switching performance, excellent mechanical durability, & long service life. Its compact & rugged construction allows easy installation in switchboards, control panels, & distribution boards while optimizing available panel space.
The DU100D series is widely recognized for delivering reliable protection, safety, affordability, & consistent performance, making it a practical choice for installations requiring effective circuit protection without the need for higher breaking capacity MCCBs.
