CM90905OOPO Lauritz Knudsen MCCB dsine DU250 - 250 A, 2 Pole, 65 kA at 240 V AC / 15 kA at 250 V DC, Thermal-Magnetic Release

The Lauritz Knudsen CM90905OOPO is the MCCB dsine DU250 - 250 A, 2 Pole, 65 kA at 240 V AC / 15 kA at 250 V DC, Thermal-Magnetic Release. Moulded case circuit breaker, dsine DU250, 2 Pole, thermal release range 200-250 A, breaking capacity Icu 65 kA at 240 V AC / 15 kA at 250 V DC. Overload setting adjustable 0.8 - 1.0 x In.

The Lauritz Knudsen CM90905OOPO is used as an incoming or outgoing breaker in main distribution boards (MDBs), sub-distribution boards (SDBs), motor control centers (MCCs), power control centers (PCCs) and feeder circuits, for loads up to 250A.

MCCBs of this type are commonly fitted with a shunt release for remote tripping, an undervoltage release, auxiliary and alarm contacts for status signalling, a motor operator for remote switching, rotary handles for door-mounted operation, extended or spreader terminals, and padlocking devices. Availability depends on the frame size, so check the Lauritz Knudsen accessory list for the CM90905OOPO before ordering.

A thermal magnetic release uses a bimetal for overload and an electromagnet for short-circuit protection. It is simple and cost-effective for standard feeders. An electronic or microprocessor release measures current electronically and offers adjustable overload, short-circuit and, on some versions, earth fault settings. It is preferred where finer coordination between breakers is needed. Lauritz Knudsen names its microprocessor releases MTX on dsine DN breakers and iTRP on dsine DZ breakers.

Calculate the prospective short-circuit current at the point of installation from the transformer kVA and percentage impedance (plus the upstream fault level), reduced by the cable impedance in between, then select an MCCB whose breaking capacity (Icu) at your system voltage (415V) is at least that value. Where supply must continue after a fault, check the service breaking capacity (Ics) too. Breaking capacity versions differ by brand and frame size, so always read the kA value for the exact model.
