3 Phase Voltage Monitoring Protective Relay
The DPA53 series 3 phase voltage monitoring protective relay is a subminiature, rail-mountable device designed for cabinet installation in distribution systems. It provides phase failure protection, phase sequence protection, voltage unbalance detection, and adjustable undervoltage protection, with models tailored for line or phase voltage inputs. The ultra-thin 17.5mm profile allows dense panel mounting, ideal for space-constrained electrical enclosures.
Constructed with sealed contacts for high-power switching, the relay measures its own supply voltage to detect faults such as phase loss, reverse phase sequence, or zero-line disconnection (in N-type models). Input voltage ranges vary by model: DPA53CM23 supports 200 - 240V AC ±15% (line voltage), while DPA53AM48N covers 220 - 277V AC ±15% (phase voltage). Standard industry relays of this type typically offer response times under 100ms and operate within -20°C to 60°C ambient temperatures.
This relay is used in distribution cabinets, control boxes, and machine tools where three-phase power stability is critical. Buyers should confirm the model variant (e.g., DPA53CM23 or DPA53AM23N) to match their system’s voltage and protection needs. Trade terms, including MOQ and lead time, should be clarified with Yueqing Aidun Electric, as the listing does not specify these details.
| Product Series | DPA53 |
| Type | Voltage Relay |
| Mounting Style | Ultra-thin (17.5mm) rail mounting |

Sourcing 3 Phase Voltage Monitoring Protective Relay from Yueqing Aidun Electric Co., Ltd - China Import Guide
Before placing an order, confirm the exact DPA53 model variant (e.g., CM23, AM48N) to ensure compatibility with your system’s voltage and protection needs. Request the supplier’s technical datasheet to verify input ranges, protection functions, and response times. Cross-check the relay’s dimensions (17.5mm width) with your cabinet’s rail mounting space to avoid fitment issues.
Clarify logistics terms, including MOQ, lead time for production, and packaging for bulk shipments. Yueqing’s proximity to major ports in Zhejiang (e.g., Ningbo) facilitates efficient export, but confirm Incoterms (e.g., FOB Ningbo) and payment methods (e.g., TT, LC) directly. Factor in potential delays for customization or high demand periods.
Quality validation should include pre-shipment testing of the relay’s protection functions (e.g., phase sequence reversal, undervoltage simulation) and verification of its sealed contact load rating. Request certificates of conformity or third-party test reports (e.g., CE, RoHS) to confirm compliance with safety and performance standards. Document warranty terms and after-sales support for troubleshooting or replacements.
