EM90983OOKO Lauritz Knudsen MCCB dsine DY125U - 100 A, 3 Pole, 10 kA at 415 V AC / 10 kA at 250 V DC, Thermal-Magnetic Release

The Lauritz Knudsen EM90983OOKO is a 3-pole moulded case circuit breaker rated at 100A with 10kA breaking capacity. It is fitted with a thermal-magnetic release for overload and short-circuit protection. It is used for protection of LT distribution circuits in industrial and commercial installations.

Choose the Lauritz Knudsen EM90983OOKO when your circuit needs 100A protection and the prospective fault current at the point of installation is within 10kA. 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 EM90983OOKO 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 100A.

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 EM90983OOKO 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.
