Olfeld Monitoring Relays are precision-engineered devices designed to detect anomalies and ensure the safe operation of electrical systems across various industrial and commercial setups. These smart relays continuously monitor critical parameters like voltage, current, phase sequence, frequency, temperature, and power factor, offering immediate response in case of deviations that could lead to system failure or equipment damage.

Built to meet the highest standards of reliability, Olfeld monitoring relays are equipped with adjustable thresholds, LED status indicators, and fail-safe outputs to deliver real-time protection and diagnostics. Whether safeguarding motors, generators, pumps, or sensitive control systems, our relays help prevent costly downtime caused by phase loss, undervoltage, overvoltage, or asymmetry.

With compact DIN-rail mountable designs, these relays fit seamlessly into modern control panels and automation cabinets. The devices support multi-voltage ranges and feature wide input compatibility, making them suitable for both single-phase and three-phase systems. Additionally, their plug-and-play configuration ensures easy integration during retrofits or new installations.

Manufactured with durable components and rigorously tested to IEC and EN standards, Olfeld monitoring relays are ideal for industries where electrical reliability is mission-critical—such as manufacturing, utilities, HVAC, and infrastructure. They provide peace of mind by ensuring your operations remain protected 24/7.
