EconiQ® Dead Tank Circuit Breaker 245 kV

The EconiQ 245PM63 HA Dead Tank Circuit Breaker (DTB) is part of Hitachi Energy’s eco efficient EconiQ portfolio, designed to enable reliable grid operation while significantly reducing environmental im-pact. It is based on well-proven gas circuit breaker technology, using a gas mixture of carbon dioxide (CO₂), oxygen (O₂) and C4-fluoronitrile (C4-FN). The mixture essentially eliminates the CO₂ equivalent emissions of the insulating medium.

This product offers easy operation at high-performance ratings without the use of SF₆. It supports utilities on their path to carbon-neutral networks.

EconiQ is Hitachi Energy’s eco-efficient portfolio for sustainability, where products, services and solutions are proven to deliver exceptional environmental performance.

• Suitable for all typical breaker applications such as line, transformer, capacitor, and reactor switching
• Fit for high seismic activity, high wind speed and high-altitude environments

• Designed to comply with chopped wave requirement and service capability test, ensuring robustness under demanding conditions
• Slipover current transformers that are added or removed without bushing removal, reducing maintenance downtime and eliminating contamination risk
• Tested according to IEEE and IEC standards with mechanical endurance class M2 and capacitive switching class C2

• Zero SF₆ emissions and superior lifecycle assessment
• Comparable gas handling procedure to SF₆ breakers, minimizing training effort and adaptation of service concepts
• Identical gas mixture across the EconiQ metal-enclosed circuit breaker portfolio
• Soft switching characteristics of gas-circuit breaker with low stress to neighboring equipment
