CM94153OOOOAG Lauritz Knudsen MCCB dsine DN3 - 400 A, 4 Pole, 70 kA, Microprocessor Release MTX2.0

The Lauritz Knudsen CM94153OOOOAG is a 4-pole moulded case circuit breaker rated at 400A with 70kA breaking capacity. It is fitted with a microprocessor MTX2.0 release for overload and short-circuit protection and belongs to the dsine DN3 frame. It is used for protection of LT distribution circuits in industrial and commercial installations.

Choose the Lauritz Knudsen CM94153OOOOAG when your circuit needs 400A protection and the prospective fault current at the point of installation is within 70kA. It gives overload and short-circuit protection in one device. Accessories for remote tripping, status indication and operation differ by frame, so confirm the accessory list for this frame in the Lauritz Knudsen catalogue.

The Lauritz Knudsen CM94153OOOOAG 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 400A.

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 CM94153OOOOAG 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. In the Lauritz Knudsen dsine DN and DZ ranges the letter in the type designation shows the Icu at 415V AC: C = 25kA, D = 36kA, N = 50kA, S = 70kA, H = 80kA. Other Lauritz Knudsen MCCB ranges use the letters differently, so always read the kA value stated for the exact model.
