The switchgear is manufactured worldwide and there are more thanUniGear ZS1 is the ABB mainline switchgear for primary distribution up to 24 kV, 4 000 A, 63 kA. The switchgear is manufactured worldwide and there are more than 400 000 panels currently installed.Main technical parameters of the switchboard:Rated power frequency withstand voltage (1 Min)(kV):42Rated lightning impulse ithstand voltage (Peak)(kV):75Rated current of main busbar(A):30, 1250, 1600, 2000, 2500, 3150Rated current of branch busbar(A):630, 1250, 1600, 2000, 2500, 3150.Rated thermal stability current (/ 3s kA):25, 31.5, 40, 50.Rated dynamical stability current (Peak)(kA):63, 80, 100, 125.Dimension(WxDxH)(mm):800(1000)x1500x2300.Enclosure protective degree:IP4X IP2X when door of breaker chamber is open. It can be combined with the other UniGear ZS1 panel widths to meet the different needs ABB’s well-known and widely accepted UniGear ZS1 is also available with a slim width panel of only 500 mm. The well-established medium-voltage switchgear offers the high safety for personnel, enhanced switchgear reliability, and smart monitoring & diagnosticKYN*8-12(Z) Metal-clad Removable AC Metal-enclosed Switchgear(hereinafter referred to as switchgear)is a power distribution device that rated voltage 3.6~12KV, three-phase AC 50/60Hz single busbar and busbar section system.
Unigear Zs1 Abb Manual Begins With
Misuse, and including in particular, duplication andmaking this manual - or extracts thereof available to third parties is prohibited. UniGear ZS1 Installation, service and maintenanceYour safety first at all times!This is why our instruction manual begins with the following recommendations:Only install switchgear and/or switchboards in closed rooms suitable for electrical equip-ment.Ensure that installation, operation and maintenance are only carried out by specialistelectricians only.Fully comply with the legally recognized standards (IEC or local), the connection conditionsof the local electrical utility and the applicable safety at work regulations.Observe the relevant information in the instruction manual for all actions involvingswitchgear and switchboards.Danger!Pay special attention to the hazard notes in the instruction manual marked with this warningsymbol.Make sure that the specified data are not exceeded under switchgear or switchboardoperating conditions.Keep the instruction manual accessible to all personnel involved in installation, operationand maintenance.The users personnel must act responsibly in all matters affecting safety at work and correcthandling of the switchgear.WARNINGAlways follow the instruction manual and respect the rulesOf good engineering practice !Hazardous voltageCan cause electrical shocks and burns.Disconnect power, then earth and short-circuit before proceedingIf you have any further questions about this instruction manual, the members of our fieldorganization will be pleased to provide the required information.We reserve all rights to this publication. The performance of the power distribution unit is advantage us and the vacuum breaker could be chosen from ZN*3-12 type that is developed by our company or the VD4 and VS1 type made by ABB Co.
