Caliber Interconnect Solutions Private Limited, a global engineering and deep-tech solutions company, has introduced its latest Three Phase Monitoring Relay, to address the growing need for reliable electrical protection across India’s industrial, infrastructure, and renewable energy sectors.
As industries increasingly operate in environments affected by voltage fluctuations and power quality challenges, the relay is designed to deliver accurate and dependable monitoring. Built on True RMS (TRMS) measurement principles, it provides precise voltage assessment even under distorted or unstable electrical conditions—an essential requirement for modern manufacturing, HVAC, power distribution, and solar installations.
Suresh Babu, Managing Director, Caliber Interconnects, said, “With rapid electrification and automation across Indian industry, electrical reliability has become a foundational requirement. This Three Phase Monitoring Relay is engineered to ensure consistent system protection and operational continuity in real-world conditions.”
The relay continuously monitors all three phases and detects critical electrical anomalies, including over-voltage and under-voltage with configurable thresholds, phase imbalance, phase loss, and phase sequence faults—issues that are among the most common causes of industrial equipment failure. Clear LED fault indications enable quick identification and troubleshooting at the panel level, supporting faster response by maintenance teams.
Manufactured using UL 94 V-0 grade flame-retardant material, the device emphasizes safety and durability. Its compact 19.1 mm footprint and fast response time of under two seconds make it suitable for space-constrained panels and contemporary industrial control systems.
Designed and manufactured in India, the Three Phase Monitoring Relay aligns with the country’s focus on electrical safety, energy efficiency, and resilient industrial infrastructure. Caliber Interconnects brings over two decades of experience in delivering high-reliability engineering and product solutions across semiconductors, automotive, railways, avionics, and medical sectors, serving customers in India, Singapore, the United States, Japan, Malaysia, and Israel. The company is ISO 9001, AS9100D, and ISO 27001 certified.
The Three Phase Monitoring Relay is suitable for a wide range of applications including industrial machinery, HVAC systems, motors, generators, pumps, compressors, solar energy systems, and electrical control panels. It is available through Caliber Interconnects’ offices in Bengaluru and Coimbatore, supporting deployment across India.
