Switch Disconnectors

Gruppo Energia switch disconnector will rapidly and safely disconnect the capacitor bank from the main circuit.

Our three-pole load break switches are compact and manually-operated. They are designed to connect (make) and disconnect (break) under load conditions.

Gruppo Energia switch disconnectors  ensure safe isolation and are suitable for individual enclosures, switch boards, lighting and power panels.

Reasons to choose our switch disconnectors:

  • They are great value for money; 
  • You can save space thanks to their compact design;
  • You can save time and money as they require little maintenance and are very durable; 
  • They are suitable for horizontal and vertical installation;
  • Door interlock and padlock facility.

The choice of a circuit breaker depends on the rated current of the power factor correction equipment.

Do you need help in selecting the correct switch disconnector for your PFC panel? Below you can see an example of the calculation that will help you perform this task easily. 

 

Standards:

DIN EN 60947-1: 2015-09; VDE 0660-100: 2015-09

Origin: 100% made in Italy

Please consult the table below for more information about how to calculate the rated current. 

 

Load break switch for capacitor banks

GE-VC-3:

In order to correctly choose a circuit breaker, you must consider the rated current of the PFC equipment, which must be calculated as follows:

1,5 x [Total Power/(System Voltage x 1,73)]

Example:

Capacitor bank with Intact Plus capacitors.

Total Power: 250 kVar at 400 V, 50 Hz

===> 1,5 x [250 kVar/(0,4 V x 1,73)] = 1,5 x 361,3 A = 542 A

In this case the best choice would be a 630 A switch disconnector (order code GE630K3).
