The TERA Brake Resistors for medium and very large drives. These resistors are cooled by either natural or forced air.
Neutral Grounding Resistors for high voltage power networks.
The TERA resistors are modular and can be assembled to fulfill all requirements for Power.
Power Range: From 3 kW to "X" MW
Protection Degree: IP00 – IP23
Two types of resistor material are available:
Type BRC; High Temperature , Low temperature coefficient: Cr,Al,Fe:(Ferritic Stainless Steel EN1-4724)
Type BRD; High Corrosive Resistance, High Temperature coefficient: Aisi 304.
The following data are valid for EN 1-4724 Resistors
