Service condition

1. Ambient temperature: -5'C~+40'C. Average temperature in 24 hours <= 35'C.

2. Altitude: <=2000m.

3. Air humidity at 40'C <=50%. Higher humidity at lower temperature is permitted. Occasional condensation due to temperature variation should be considered.

Special condition subject to users.

Features and Benefits

1.SICO MNS switchgear assembles 4, 2 or 1 drawer units in the space of 8E height, or 1 unit in 16E or 24E. SICO GCS switchgear drawers are divided into 1/2, 1, 2, 3 units

2.Breaker compartment doors have no ventilation openings, thus protecting operators from hot ionized gases vented by the breaker during circuit interruption.

3.A superior bus system offers different levels of protection. Insulated and isolated bus makes maintenance procedures touch friendly to reduce the risk of arc flash.

4.True closed-door drawout construction is standard with all SICO GCS, SICO MNS equipment. The breaker compartment doors remain stationary and closed while the breaker is racked out from the connect position, through test, to the disconnect position. Doors are secured with rugged 1/4-turn latches.

5.An easy-to-read metal instrument panel above each circuit breaker holds a variety of control circuit devices, including the RELT switch.

6.Each circuit breaker is located in a completely enclosed ventilated compartment with grounded steel barriers to minimize the possibility of fault communication between compartments.

7.Optional safety shutters protect operators from accidental contact with live conductors when the breaker is withdrawn.

8.Easy access to equipment compartments simplifies maintenance of the breaker cubicle and control circuit elements as well as inspection of the bolted bus connections.

9.A rail-mounted hoist on top of the switchgear provides the means for installing and removing breakers from the equipment. This is a standard feature on NEMA 3R outdoor walk-in construction and optional on indoor construction.

10.Control wires run between compartments in steel riser channels. Customer terminal blocks are located in metal-enclosed wire troughs in the rear cable area. Intercubicle wiring is run in a wireway on top of the switchgear, where interconnection terminal blocks are located.

11.All circuit breakers are equipped with rollers and a guidebar to provide easy and accurate drawout operation.

12.An optional remote racking device reduces the risk of the arc flash hazard by allowing the operator or electrician to move the breaker anywhere between the DISCONNECT and CONNECT positions from outside the arc flash boundary.

13.Optional infrared (IR) scanning windows can be installed in the switchgear rear covers to facilitate the use of IR cameras for thermally scanning cable terminations.

14.SICO GCS, SICO MNS switchgear can be expanded easily to handle increased loading and system changes. Specify a requirement for a fully equipped future breaker to obtain a cubicle that has been set up for additional breaker installation, or add vertical sections without modifications or the use of transition sections.

15.An array of safety interlock and padlocking features are available to accommodate any type of lockout-tagout procedure a customer may have.

16.Optional Power Management: With the proper devices, facility power can be tracked and controlled.
