Here's the complete expanded description for the Minilec D2 VCT 1 Voltage Protection Relay:

Specifications (existing/cleaned up)

• Model: Minilec D2 VCT 1
• Type: Voltage Protection Relay (3-phase supply monitoring)
• Function: Detects under-voltage, over-voltage, single-phasing, and phase reversal
• Supply Voltage: 3-phase, 415V AC (typical)
• Output: Relay contact to trip connected contactor/starter
• Adjustability: Adjustable trip thresholds (voltage range/delay, model-dependent)
• Mounting: DIN rail or panel mounting
• Reset: Auto-reset once voltage normalizes (model-dependent)

What is this product?

The Minilec D2 VCT 1 is a voltage protection relay that continuously monitors 3-phase supply and disconnects connected equipment when it detects unsafe voltage conditions like under-voltage, over-voltage, single-phasing, or phase reversal. It's installed ahead of motor starters and sensitive equipment to prevent damage from unstable grid supply.

Where is it used?

• 3-phase motor and pump starter panels
• Industrial machinery panels sensitive to voltage fluctuation
• Agricultural and submersible pump control panels
• Refrigeration and compressor control circuits
• Panels feeding sensitive electronic or automation equipment requiring stable supply

Key technical advantages

The D2 VCT 1 stands out for covering multiple fault conditions in a single device — under-voltage, over-voltage, single-phasing, and phase reversal — rather than needing separate relays for each fault type, which simplifies panel design and reduces wiring complexity. This broad protection is especially valuable on India's often unstable rural and semi-urban grid supply, where voltage sags, surges, and phase loss are common and can silently damage motors and equipment over time. Minilec's adjustable trip thresholds let panel builders fine-tune sensitivity to match the specific equipment being protected, rather than relying on a fixed, one-size-fits-all trip point. Its fast detection and trip response also protects downstream contactors and starters from repeated stress caused by nuisance restarts during unstable supply conditions.

FAQs

Q: Can I adjust the voltage trip points on the D2 VCT 1, or are they fixed?
A: The D2 VCT 1 typically offers adjustable under-voltage and over-voltage trip thresholds so you can set them to match your specific motor or equipment's tolerance — let us know your application and we can guide you through the setting process.

Q: Does the D2 VCT 1 also protect against phase reversal, or only voltage issues?
A: Yes, in addition to under/over-voltage protection, the D2 VCT 1 typically also detects phase reversal and single-phasing, giving broader protection than a voltage-only relay — this is especially useful for pump applications where reverse rotation can damage the pump.

Q: Does the panel restart automatically once voltage returns to normal, or is manual reset required?
A: This depends on the specific configuration — some Minilec D2 VCT 1 variants auto-reset once supply stabilizes, while others require manual reset for safety in unattended installations. Let us know your setup and we'll confirm the reset behavior for your unit.
