TG30 3-Phase Phase Sequence Relay Kadimendium Power Monitor for Motors

Description

Product Overview

The TG30 3‑Phase Phase Sequence Relay by Kadimendium is engineered to provide comprehensive monitoring and protection for three‑phase power systems used in industrial machinery. Built with a robust housing and high‑quality internal components, the relay reliably detects a range of fault conditions, including reverse phase rotation, voltage imbalance, missing phase, and short‑circuit events. Its integrated circuit continuously samples the incoming voltage waveforms, compares phase relationships, and triggers an internal contact to disconnect the load when an abnormal condition is identified. This rapid response helps prevent costly equipment damage, unplanned downtime, and safety hazards.

Designed for a voltage range of 220‑380 VAC, the TG30 fits seamlessly into standard control panels and can be mounted using the provided DIN‑rail brackets. The relay’s compact dimensions—3.15 × 2.76 × 1.57 inches—and lightweight construction (approximately 1 lb) make it suitable for space‑constrained installations while still delivering the durability required for harsh industrial environments. The device complies with international safety standards and has earned a strong reputation, ranking #13 in the Phase Monitoring Relays category on major e‑commerce platforms.

Key technical specifications include a contact rating of 10 A at 250 VAC, a coil voltage of 220‑380 VAC, and a response time of less than 10 ms. The relay operates without the need for external power supplies, drawing its operating energy directly from the monitored three‑phase line. This self‑powered design simplifies wiring, reduces installation costs, and enhances reliability by eliminating dependence on auxiliary power sources.

In addition to its core protective functions, the TG30 features an LED indicator that provides visual status feedback, allowing technicians to quickly assess the relay’s condition during routine maintenance. The indicator illuminates green when the power supply is normal and switches to red when a fault is detected, facilitating rapid troubleshooting and minimizing service interruptions.

Usage

The TG30 relay is ideally suited for a wide variety of three‑phase equipment, including electric motors, centrifugal pumps, refrigeration compressors, fans, air compressors, elevators, and injection molding machines. Its ability to detect phase anomalies makes it an essential component in facilities where continuous operation and equipment longevity are critical, such as manufacturing plants, water treatment facilities, and large‑scale HVAC systems.

Installation is straightforward: connect the relay’s input terminals to the three‑phase supply lines, and wire the output contacts in series with the load’s power circuit. Once installed, the relay continuously monitors the phase sequence and voltage balance, automatically disconnecting the load if any deviation exceeds preset thresholds. This proactive protection helps avoid motor winding damage, bearing failures, and costly repairs caused by improper phase rotation or voltage fluctuations.

Maintenance requirements are minimal. The relay’s solid‑state detection circuitry requires no periodic calibration, and the mechanical contacts are rated for millions of operations, ensuring long‑term reliability. For routine checks, technicians can simply observe the LED status indicator and verify that the relay’s contacts open and close as expected during simulated fault conditions.

FAQ

What voltage range does the TG30 support?

The TG30 is rated for a three‑phase input voltage range of 220 VAC to 380 VAC, making it compatible with most industrial power systems worldwide.

Can the relay be used with variable frequency drives (VFDs)?

Yes, the TG30 can be installed upstream of VFDs. It monitors the incoming supply before the VFD, ensuring that any phase or voltage anomalies are detected and the load is protected before the drive processes the power.

How does the LED indicator help during maintenance?

The built‑in LED provides immediate visual feedback: a steady green light indicates normal operation, while a red light signals a detected fault. This allows technicians to quickly identify issues without needing specialized test equipment.

What is the contact rating of the relay?

The output contacts are rated for 10 A at 250 VAC, suitable for most motor and pump applications. For higher current loads, multiple relays can be paralleled or a relay with a higher rating can be selected.

Is there a warranty or after‑sales service?

Kadimendium offers a standard one‑year warranty covering manufacturing defects, along with access to technical support, replacement parts, and detailed documentation to assist customers throughout the product’s lifecycle.
