Description
About the Product
The Lauritz Knudsen CM90517OOEO from the DU100D series is a dependable 3 Pole Moulded Case Circuit Breaker (MCCB) designed to provide efficient circuit protection for residential, commercial, & light industrial electrical systems. Rated at 32A & 415V AC, this MCCB protects electrical circuits, power distribution networks, & connected equipment from overloads & short-circuit faults while ensuring safe & reliable operation.
The breaker incorporates an advanced thermal-magnetic trip mechanism that provides dual protection against electrical abnormalities. The thermal protection element delivers time-delayed tripping during overload conditions, helping prevent overheating & damage to cables, conductors, & electrical equipment caused by excessive current flow. The magnetic protection element responds instantaneously to short-circuit faults, rapidly isolating the affected circuit & minimizing the risk of equipment damage & electrical hazards.
With a breaking capacity of 18kA, the DU100D MCCB is well suited for applications with low to medium fault levels. This fault interruption capability provides dependable system protection while offering an economical solution for standard power distribution requirements where higher fault ratings are not necessary.
The MCCB is designed for operation on standard 50/60 Hz electrical systems, ensuring compatibility with a broad range of residential, commercial, & light industrial installations. Its 3 Pole configuration is ideal for three-phase electrical systems commonly used in commercial facilities, apartment complexes, workshops, & distribution panels.
Manufactured using durable insulating materials & precision-engineered internal components, the breaker offers reliable electrical performance, excellent mechanical durability, & long service life. Its compact design allows easy installation in distribution boards, switchboards, & control panels while maximizing available installation space.
The DU100D series is recognized as a cost-effective & reliable protection solution for installations requiring dependable performance, efficient protection, & economical operation without the need for higher breaking capacity MCCBs.
