The Vector FS series is ideally situated where floor space is limited

Soft Switching contactors for minimal system disturbance

Also available with harmonic blocking or filter reactors

Multi-stage switching with on/off/auto facility available on the control relay

Panel mounted on/off/auto switches and indicator lamps available as low cost option

A suitably rated switch-fuse, circuit-breaker or loadbreak switch is available as an option where required

Construction
The enclosure is of robust steel construction and is designed for total front access via a hinged door. Top or side cable entry is provided as standard. Bottom cable entry is also available upon request. The unit utilises an SBA type modular equipment tray system. Each equipment tray includes the requisite
capacitors, soft switching contactors, auxiliary and control fuses. This system greatly simplifies modification or upgrade.

Control Gear
The equipment incorporates a special soft switching contactor arrangement to minimise system disturbance which is caused by capacitor switching. For example, a 50kVAr automatic step is controlled by two contactors switching in cascade. These contactors incorporate a pre-connection resistor system which reduces the effect of current inrush, thus reducing system disturbance and increasing product life. 100 Amp circuit fuses are installed to protect each 50kVAr capacitor step and its associated control gear.

Capacitors
The capacitor unit comprises the requisite number of individual capacitor elements. These elements are manufactured from impregnated metallized polypropylene or metallized paper and plastic film and have a self-healing capacity. Each one incorporates a fail-safe protection device.
