SL94827 Lauritz Knudsen ACB C-Power 4000 A - 4 Pole, Manual Draw-out, Microprocessor Release SR18G

The Lauritz Knudsen SL94827 is a 4-pole air circuit breaker rated at 4000A with 75kA breaking capacity, in manual draw-out construction. It is fitted with a microprocessor SR18G release.

The Lauritz Knudsen SL94827 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 4000A.

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. Draw-out versions also use racking interlocks and position-indicating microswitches. Check the Lauritz Knudsen accessory list for the SL94827 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.
