Series TTE
Three-phase encapsulated isolating transformer
Series TTE
Three-phase encapsulated isolating transformer
Three-phase transformer with galvanic isolation between primary and secondary, with excellent attenuation against electrical disturbances.
Encapsulated in very robust resin with high thermal dissipation power. Increases the mechanical resistance to the electrodynamic stresses of the winding, extending the useful life of the insulation.
Suitable for vibrating, humid, saline or corrosive environments.
Features
- Winding completely protected against shocks, dust, dirt and humidity.
- Transparent cover to protect the connection terminals to avoid the risk of accident due to electrical contact.
- Built-in lifting eyelets or eyebolts.
- Low-loss magnetic core impregnated with anti-rust epoxy varnish.
- Improved reliability when working in vibrating environments.

Uses
For general use as galvanic isolation between mains and load.
To generate a neutral independent of the grid free from common mode electrical disturbances.
In three-phase systems to generate a system with a TN-S or TN-C neutral depending on the type of installation, it requires additional residual current circuit breaker protection.
For three-phase isolated three-phase IT systems, it requires additional protection by an insulation monitor.
