The reduced energy requirements of the breaking chamber allows for the utilization of the world class FK spring-spring mechanism. The combination of the proven FK drive mechanism and interrupter technology results in a significant reduction of reaction forces, thus reducing foundation design requirements.

Gas Tightness Guarantee

GE Vernova leads the industry in SF₆ gas tightness testing technology including seals, castings, and plumbing systems. Each breaker is factory tested using GE Vernova’s proprietary gas tightness testing system which provides measurable, quantifiable test results on the breaker in its fully assembled, as-shipped condition.

Certified Quality

GE Vernova designs, manufactures, tests and delivers its circuit breakers in accordance with the latest IEEE/ANSI and IEC standards, maintaining a quality assurance system according to ISO-9011 and ISO-14001 certifications. The center of excellence for dead tank circuit breakers is located in Charleroi, PA.

Installation and Maintenance

The DT1-245 series is factory tested and prepared for shipment with bushings assembled and prefilled with SF₆ gas, therefore the on-site installation requires only a few simple steps without requiring any special tools. The DT1-245 circuit breaker range has lower maintenance costs and requirements, thanks to an engineering and design philosophy that has focused on these key needs since the inception of the development process.

The center of excellence for dead tank circuit breakers is located in Charleroi, PA.

Installation and Maintenance

The DT1-145R is factory tested and adjusted and don’t require any special tools for installation. Designed with the smallest symmetrical footprint to allow for minimized foundation costs, they are recognized worldwide as easy-to-install and operate circuit breakers. Thanks to the low energy mechanism and lifetime lubricants, the DT series is virtually maintenance free.

The DT1 series on-site installation requires only a few simple steps. For installations where truck shipment is impossible, all DT series circuit breakers can be readied for standard container shipment with only their bushings disassembled.

Pre-insertion Resistors (PIRs)

The circuit breaker random switching can generate voltage disturbances on electrical lines. Placed in parallel of the main contacts of a circuit breaker, a pre-insertion resistor is a technique consisting in operating the circuit-breaker while briefly inserting a resistor during closing operation to reduce overvoltage phenomena such as switching transient voltage. This helps limit the power quality issues and accelerated aging, thus minimizing risks and operation costs. Integral PIRs may be used for switching of lines, transformers, shunt capacitors or shunt reactors.
