Product Details

The identity part of KYN□-24 reads position by position: K is metal-clad enclosed switchgear, Y is the withdrawable pattern, N is indoor service, the box is the design code and 24 is the voltage class. The box is not a printing omission — it is filled with the specific design code, and one voltage class can carry more than one design. A complete order designation adds the primary scheme number, operating-mechanism code (D for magnetic, T for spring), rated current and rated breaking current, all settled at quotation.

Two points on this model are worth reading on their own. First, rated frequency is given as 50 / 60 Hz where the rest of the series gives 50 Hz only. In a 60 Hz market this is a precondition for the equipment entering site rather than a parameter adjusted there, so stating the system frequency with the enquiry is enough to match the configuration. Second, the cubicle measures 1000 x 1910 x 2400 mm at 840 to 1500 kg by configuration — the 40.5 kV member of the same series runs to 1400 x 2800 x 2800, so this one is far lighter on both switchroom area and floor loading, which suits distribution rooms limited in height and area. Auxiliary and control circuits are rated DC or AC 110 / 220 V with a 2000 V power-frequency withstand.

Product FAQs

Yes. Rated frequency covers both 50 and 60 Hz on this model, the one in the KYN series that gives 60 Hz; the others give 50 Hz only. Frequency drives the matching of instrument transformers, protection relays and operating mechanisms, so it is fixed once at ordering rather than adjusted on site. State the system frequency and rated voltage with the enquiry and the configuration matches first time.

It follows the system voltage. A 20 kV nominal system needs 24 kV equipment; a 10 kV system is served by 12 kV equipment and does not need a step up. The 20 kV distribution network is more common in some overseas markets than at home, and that is where this model mostly goes. A 35 kV system takes KYN61-40.5 instead; the series page carries the full five-model comparison.

The envelope is 1000 wide, 1910 deep and 2400 high; weight runs 840 to 1500 kg, the spread coming from the primary scheme and component fit, with the final figure following the confirmed configuration. Three things are checked together: the switchroom depth has to take the cubicle plus front operating and maintenance space and the truck withdrawal travel, the floor or foundation is checked against the per-cubicle upper figure, and transport and craneage against the whole envelope. Send the switchroom layout and floor loading conditions and it can be confirmed during quotation.

Auxiliary and control circuits are rated DC or AC 110 / 220 V with a 2000 V power-frequency withstand on the secondary circuits. What has to be stated at ordering is the supply type — DC or AC — the voltage level, and whether dual supplies with changeover are required. Those three drive the operating mechanism, protection and signalling selection, and they are fixed once during the technical agreement.

Four things give a preliminary scheme: the single-line diagram, system nominal voltage, system frequency and system fault capacity. For a contract-grade quotation, add the cubicle count with each primary scheme, control supply type and voltage, metering and protection requirements, cable entry arrangement and cable sizes, communication interfaces, switchroom dimensions and floor loading conditions, and the standards and document list for the destination market.

Yes. Switchgear is supplied as equipment while an MV switchgear E-House or power module is supplied as an enclosure — the first is the panel itself, the second covers the enclosure, equipment layout, auxiliary systems and interface integration. This model is compact, so a given module length takes more bays than it would with a larger cubicle type, which is often used during in-module planning. Where it goes inside as the primary equipment, ETENZ details the line-up arrangement, busbar connections and in-module interfaces, and the delivery boundary is settled once at contract stage.
