Reliable Protection for Industrial Applications

Engineered for industrial equipment and motor protection, the HLV D2 Phase Failure Relay responds rapidly to dangerous electrical conditions, such as phase loss or voltage faults. The combination of robust flame retardant housing, automatic reset, and high endurance ensures operational safety for both assets and personnel.

Compact DIN Rail Design for Easy Installation

Its slim, space-saving profile (80mm x 22.5mm x 80mm) and DIN rail mounting facilitate straightforward integration into control panels. The relays modern, white and blue casing not only provides durability but also aligns seamlessly with contemporary panel aesthetics.

Clear Status Indicators and Automatic Response

Equipped with LED status indicators, the relay offers immediate visual feedback on phase presence and fault detections. The automatic reset feature ensures instant recovery actions, minimizing manual intervention and downtime after electrical anomalies are resolved.

FAQs of Phase Failure Relay HLV D2:

Q: How does the Phase Failure Relay HLV D2 enhance industrial equipment safety?

A: The relay continuously monitors phase conditions and voltage levels. It automatically disconnects or signals if phase loss, incorrect sequence, or under/over-voltage is detected, thus protecting motors and sensitive equipment from potential damage.

Q: What is the installation process for the HLV D2 relay?

A: This relay is designed for easy DIN rail mounting inside control panels. Simply connect the supply terminals (L1, L2, L3, N) corresponding to your three-phase system, and integrate the relay contact into your circuit as required by the protective scheme.

Q: When should I use the HLV D2 relay in my electrical system?

A: The HLV D2 relay is ideal wherever three-phase, 415V AC equipment needs protectionsuch as in industries using heavy-duty motors or automation systemsespecially in environments prone to voltage fluctuations or phase anomalies.

Q: Where Should LED Indications be Referenced During Operation?

A: During operation, the LED indicators provide real-time status updates on phase presence and any detected faults. Operators should monitor these LEDs for prompt diagnostics and maintenance if a fault is indicated.

Q: What are the key benefits of the automatic reset feature?

A: The automatic reset quickly restores normal relay operation after the resolution of the detected fault, ensuring minimal disruption and reducing the need for manual intervention, especially in critical industrial setups.

Q: How durable is the HLV D2 relay?

A: Engineered for reliability, the relay provides a mechanical life of over one million operations, with high insulation resistance (>100M at 500V DC) and robust dielectric strength (2kV AC for one minute) assuring long-term, safe operation.
