GENERAL CHARACTERISTICS
The three-phase reactances in this catalog are designed and implemented with the following characteristics:

  • Cores made with metal magnetic crystal oriented to low loss. The sizes are contained.
  • Vacuum impregnation with thermosetting polyester resin class > or = F
  • Connections made through terminal blocks or similar type and adapted to the current working system for tightening conductors safe against autoallentamento.

To exceed the current 80A connections are made with sturdy terminal.

  • Enforcement of reactance according to customer requirements with the possibility of mounting horizontally.
  • They can also be supplied in container sheet steel with a degree of protection IP23.
  • UL/CSA File E309790.

 


ELECTRICAL CHARACTERISTICS

  • Not Rated
    The ballasts are designed for the frequency of 50Hz, but can also function properly at 60Hz.
  • Design
    The ballasts are sized for nr. 2 consecutive starts and no. 4 start time 5 / 10 sec.
  • Voltage: 400V
    The voltage drops vacuum are particularly dependent on output. In the product details listed in the catalog shows the data referred to:
    - Short-circuit voltage expressed as a percentage of nominal voltage primary
    - Voltage drop vacuum charged as a percentage 35%
    - Maximum torque equal to 75%.

WINDING CONNECTING
The three-phase CTA ballasts are usually made in implementing open with a degree of protection IP00.
However, they may also be supplied in container sheet steel painted with a degree of protection IP23.
At the request may also be supplied with reactance characteristics different from those of normal production and outlined in this catalog.

WARNINGS FOR WIRING
Verify that the temperatures of reactance into the not exceed the limits prescribed by the rules.
Use the appropriate cables according to the current game and the capacity of the terminals. In addition to special care not to tighten the insulating sheaths under the terminal screws. In fact, a bad contact can lead to localized heating that can lead to damage to components.
The installation and replacement of reactance must be performed by qualified persons.
