Product Description
The N22-EFR/d senses total current passing from the DC system on Positive or Negative BUS & calculate leakage current passing through earth if any. The relay operates when the leakage current goes above the range selected on dial provided on front. It has Fault level setting from 1% to 10% of rated current sensor, for e.g. for Sensor A (25A) it shall be=250mA-2.5A with resolution in 10 steps. It also has time delay setting from 1 to 10 sec for delay in relay operation after fault occurs. The relay has one change over set of contacts.
Reliable Earth Fault Protection
The N22-EFR/d DC Earth Fault Relay provides effective detection of earth faults in low power DC systems. Its swift response reduces risk to equipment, ensuring your system remains safe and operational without unnecessary interruptions.
Engineered for Efficiency
With its low power contact load, the relay supports energy-conscious facilities and systems. It is designed to operate efficiently while providing consistent performance, making it suitable for modern, low-energy applications across various sectors.
Expert Manufacturing in India
Manufactured and exported from India, the N22-EFR/d ensures quality and dependability through strict adherence to industry standards, advanced engineering, and rigorous quality controls. Customers worldwide trust in its reliable protection and efficiency.
FAQ's of DC Earth Fault Relays N22-EFR/d:
Q: How does the N22-EFR/d DC Earth Fault Relay function in a power system?
A: The N22-EFR/d relay detects insulation failures or unintentional connections between the DC system and ground (earth faults). When such a fault occurs, it activates a signal or output to alert operators and trigger protective actions, safeguarding your equipment.Q: What are the benefits of choosing a low power contact load relay like the N22-EFR/d?
A: Low power contact load relays reduce overall energy consumption, minimize heat generation, and extend equipment life. They are particularly useful for energy-sensitive applications that require reliable protection without increasing operational costs.Q: When should a DC earth fault relay be installed in an electrical system?
A: It is recommended to install a DC earth fault relay during the initial setup of a DC power system, or when upgrading existing systems to enhance protection against earth faults and prevent equipment damage or service disruptions.Q: Where is the N22-EFR/d DC Earth Fault Relay commonly used?
A: This relay is primarily used in industrial plants, utility substations, telecommunications, and renewable energy installations where DC systems are prevalent. Its adaptability and reliability make it ideal for critical infrastructure and sensitive environments.Q: What steps are involved in the installation process for this earth fault relay?
A: Installation generally includes mounting the relay in a control panel, connecting the supply voltage and DC system wiring, calibrating the detection threshold if required, and testing the relay's operation to ensure system safety.Q: How does using the N22-EFR/d relay benefit system operators and maintenance teams?
A: Operators and maintenance teams benefit from timely earth fault alerts, which help in diagnosing and addressing issues before they escalate. This proactive approach leads to reduced downtime, lower maintenance costs, and improved system reliability.Tell us about your requirement
