ICM Controls ICM402C Phase Relay 190600VAC Input

Description

Product Overview

The ICM402C is a robust three‑phase line voltage monitor and motor protection relay designed by ICM Controls for demanding industrial environments. Built to handle a universal input range of 190‑600 VAC, this device continuously watches each phase for loss, reversal, and voltage imbalance, instantly triggering a fault condition when parameters fall outside safe limits. Its compact dimensions—1.55 × 4.1 × 5.5 inches—and lightweight construction (6.72 oz) make it easy to install in crowded control panels without sacrificing durability.

Key to its reliability is the bright dual‑LED indicator system that provides clear visual cues: a steady green LED confirms normal operation, while a red LED flashes to signal a fault, allowing technicians to diagnose issues at a glance. The relay accepts a control voltage of 115, 208, or 240 VAC, offering flexibility for integration with a wide variety of PLCs, motor starters, and supervisory control systems.

Engineered with high‑quality components, the ICM402C meets rigorous industrial standards for temperature, vibration, and electrical noise. Its sealed enclosure protects internal circuitry from dust, moisture, and corrosive gases, ensuring long‑term performance even in harsh manufacturing plants, oil‑field rigs, or outdoor installations. The device’s simple wiring diagram and clear labeling reduce installation time and minimize the risk of wiring errors.

Beyond basic protection, the ICM402C provides valuable diagnostic data that can be fed back to a central monitoring system. By reporting phase‑loss events, reversal incidents, and percentage‑based unbalance values, it enables predictive maintenance strategies that reduce unplanned downtime and extend motor life. The relay’s fast response time—typically under 10 ms—ensures that protective actions occur well before damage can occur.

With a competitive price point of $111.06 and a proven track record reflected in a 4.3‑star rating from seven verified customers, the ICM402C delivers both cost‑effectiveness and confidence. Its best‑seller rank of #18 in the Phase Monitoring Relays category underscores its popularity among engineers seeking reliable, easy‑to‑use protection solutions.

Usage

Designed for a broad spectrum of industrial applications, the ICM402C excels in environments where three‑phase motors drive critical processes. In HVAC systems, it safeguards compressors and large fans by detecting phase loss that could otherwise cause overheating or mechanical stress. In pump stations, the relay prevents costly water‑hammer events by ensuring balanced voltage across all phases before the motor starts.

Manufacturing facilities that rely on CNC machines, conveyors, and robotic arms benefit from the ICM402C’s rapid fault detection, which helps avoid sudden shutdowns that could damage precision equipment. The device’s ability to operate on a 115‑240 VAC control voltage means it can be paired with both legacy control panels and modern PLC‑based automation platforms, making it a versatile choice for retrofits and new installations alike.

For offshore oil and gas platforms, where space is limited and reliability is paramount, the ICM402C’s compact size and sealed housing provide a rugged solution that can withstand salt‑air corrosion and temperature extremes. Its bright LED indicators are especially useful in low‑light conditions common on such sites, allowing operators to quickly assess system health without needing additional instrumentation.

In renewable energy installations, such as wind turbine generators, the relay monitors the three‑phase output to ensure that voltage imbalances do not affect power quality or cause premature bearing wear. By integrating the ICM402C into the turbine’s control logic, operators can schedule maintenance before minor imbalances evolve into major failures.

Overall, any application that relies on three‑phase power—whether in heavy industry, commercial building automation, or specialty equipment—can leverage the ICM402C to improve safety, reduce downtime, and extend the lifespan of critical motor assets.
