Medium Voltage arc Proof Air Insulated Metal Clad Switchgear 1) Medium voltage switchgearUN-panel ZS1 is medium voltage switchgear with a metal enclosure, suitable for indoor installations. Metal clad and seperate the compartments from each other's. Their live parts are air-insulated. Since the switchgear is highly modular type, this make simple selection of components required by any application. The functional units of the switchgear are guaranteed arc proof in accordance with the IEC 62271-200 Standards. All the installation, operation and maintenance operations can be carried out from the front of the switchgear. The vacuum circuit breaker and earthing switches are operated from the front with the door closed. The switchgear can be back to wall installed.
2) Protection ComponentsThe range of apparatus available for UN-panel ZS1 switchgear is the most complete on the market, including:- Withdrawable vacuum or gas VCB
- withdrawable vacuum contactor
This makes it possible to offer a single switchgear-user interface, with the same operational and maintenance procedures.
The switchgear can be fitted with instrument transformers or sensors for current and voltage measurement and protection and any brand circuit breakers or relay protection.
3) Switchgear, busbar configurationIn the completion of the traditional functional units in single busbar arrangement, the UN-panel ZS1 switchgear platform is fitted with:- Double busbar
- Compact units equipped with vacuum contactors & fuses,
- Double Busbar Systems.
4) Working conditionsAmbient conditions:For different temperature ranges, Unisun provide heater or cooling fan with temperature monitor as solutionAmbient humidity:- up to 95% RH average in 24h
- up to 90% RH average in monthly
- water vapour pressure up to 2.2 kPa in 24h
- water vapour pressure up to 1.8 kPa monthly
- The normal working altitude is up to 2,000 m above sea level. For higher altitude applications, please consult upon ordering
- Install in normal, non-corrosive and uncontaminated environment
5) StandardsUnisun ZS1 switchgear and main components comply with the following Standards:- IEC 62271-1 for general purposes.
- IEC 62271-200 for the switchgear.
- IEC 62271-102 for the earthing switch.

- IEC 62271-106 for the contactors.
- IEC 60265-1 for the switch-disconnectors.
- IEC 60529 for degree of protections.
6) Colour of the external surfaces
RAL7035 - ligh grey (front doors and side cover). Other colours are available on request.
7) Degrees of protection
The degrees of protection of the switchgear conform with IEC 60529 Standards.
UN-panel ZS1 switchgear is normally supplied with the following standard degrees of protection:
IP4X for the enclosure.
IP2X for the partition between compartments.
higher degree of protection could be customized pls contact Unisun technical dept.
