UW112NXF01900 Lauritz Knudsen ACB U-Power Omega 1250 A - 3 Pole, Manual Fixed, UW-MTX1.5G

The Lauritz Knudsen UW112NXF01900 is a 3-pole air circuit breaker rated at 1250A with 50kA breaking capacity, in manual fixed construction. It belongs to the Lauritz Knudsen U-Power Omega range.

The Lauritz Knudsen UW112NXF01900 is used as a main incomer, bus coupler or outgoing feeder breaker in LT main switchboards and power control centers (PCCs), including transformer and DG set incomers, for loads up to 1250A.

Air circuit breakers are commonly fitted with a shunt release for remote tripping, an undervoltage release, a closing coil and motor operator for electrical operation, auxiliary contacts for status signalling, and mechanical interlocks and locking devices for safe operation. Check the Lauritz Knudsen accessory list for the UW112NXF01900 before ordering.

A fixed ACB is bolted directly to the panel busbars, so it can only be removed with the panel switched off. A draw-out ACB sits in a cradle and can be racked out to the test or isolated position for maintenance and testing, and replaced quickly without disturbing the busbar connections.

Select an ACB whose rated current, after derating for the panel’s internal ambient temperature (often 50 °C in Indian panels), is at least the maximum load current of the incomer — for a transformer incomer, the transformer full-load current (about 1.39 A per kVA at 415 V) — and whose breaking capacity (Icu, and preferably Ics) is at least the prospective short-circuit current at the switchboard. Where breakers must discriminate, also check that the short-time withstand rating (Icw) covers that fault current for the required time, usually 1 second.
