Used Phase Monitoring Relays

This category is for used phase monitoring and phase protection relays. Compare the monitored voltage, neutral requirement, detected faults, threshold/delay settings and output contact rating. Verify which functions are supported by the exact model: phase sequence, phase loss, voltage imbalance and under/overvoltage monitoring.

A phase relay generally acts on the contactor's control circuit rather than interrupting motor current directly. Voltage monitoring does not imply overload or temperature protection. Assess those requirements separately under motor protection devices and thermistor relays. Technical details are available under what a phase protection relay is; new alternatives are listed under new phase protection relays.

To buy, browse the product listings in this category. Your seller is the store identified on the product page. Confirm price, availability, delivery, specifications and condition with that store. Listings should not all be treated as DERELL's own inventory.

Distinguish between used, unused, boxed, repaired, faulty and parts-only items. Known faults and missing accessories must be disclosed. Where tests have been performed, describe the phase-loss, sequence, threshold and delay checks. Test coverage, any warranty and declarations of standards compliance depend on the store's product description. A boxed or unused item does not automatically come with a warranty.

To offer a phase monitoring relay for sale, email the brand, full model number, quantity, working or faulty condition, clear photographs of the unit and its nameplate, and your asking price to otomasyonavm@gmail.com. We do not purchase products without an invoice. A submission is neither a commitment to buy nor an automatic listing service.

Listings are updated approximately every 10 days. A sold item may remain visible briefly, so confirm availability with the selling store before ordering.
