RFIX, GS / CS — fixed (unregulated) 0.4 kV PFC banks
Country: Italy · Model: RFIX / GS / CS
RFIX, GS and CS are fixed 0.4 kV reactive power compensation banks for constant loads. The wall-mounted RFIX weighs 6–7 kg and starts at 3.4 kVAr, while the cabinet-type GS and CS are designed for transformers at no load and motors with a steady load.

Description
RFIX is the newest development for fixed PFC of small loads, compact and light (6–7 kg), so it is quickly mounted on a wall. Rated voltage is 415 V (others to order), maximum voltage on the capacitors is 450 V for RFIX-B15 and 550 V for RFIX-B50, frequency 50 Hz (60 Hz to order), insulation 690 V. Standard power ratings are 3.4 / 6.25 / 12.5 / 17.5 kVAr and above. For B15 the permissible network current THD is 15 %, and the capacitor current THD is 50 %. RFIX-T has a three-pole off-load disconnector with a door interlock and NH-00 gG fuses of 100 kA, while the basic RFIX has no protection and no disconnector. Protection is IP30, cable entry from the top, natural ventilation, vertical installation indoors. GS-B15 has capacitors up to 450 V, GS-B50 and CS up to 550 V, and where there are harmonics in the network CS with blocking reactors is recommended. The capacitors are single-phase MKP with an anti-explosion device and a discharge resistor (75 V after 3 min), delta connection, overvoltage 1.1 Un, overload 1.3 In, tolerance −5/+10 %, losses up to 0.4 W/kVAr. Standards IEC/EN 60831-1/2 and IEC/EN 61921. They are used at 6–10/0.4 kV substations, in pump rooms and compressor rooms.
How to choose
If the network has harmonics, take CS with blocking reactors, and for a clean network RFIX or GS. The B15 series is chosen for a current THD of up to 15 %, and B50 for networks with a higher harmonic level. When a disconnector and fuses are needed, order RFIX-T. If the load varies, a regulated bank is needed, for example B35-ST.

FAQ
What voltage and frequency does RFIX have?
Rated voltage 415 V, frequency 50 Hz (60 Hz to order), insulation voltage 690 V.
What does the RFIX-T version add?
A three-pole off-load disconnector with a door interlock and NH-00 gG fuses of 100 kA.
What are the weight and protection degree of RFIX?
Weight 6–7 kg, protection degree IP30, installed vertically on an indoor wall.
When is the CS series needed?
When the network has harmonics, because CS has blocking anti-resonance reactors.
