The RX233 Overcurrent Relay is a mobile app-based overcurrent relay designed to enhance protection and monitoring for electrical systems. It features NFC capability, real-time monitoring, self-test and recovery, event logging, three-phase overcurrent protection, frequency settings, and configurable output contacts. The relay also supports 50 or 60 Hz frequency options and is standard compliant with IEC 60255 and ANSI codes. Its technical specifications include a current rating of 5A with a frequency of 50 or 60Hz, an accuracy of ±3%, adjustable overcurrent and thermal overload, and output contacts with a rated voltage of 250VAC. The relay operates within -10°C to 55°C, 5% to 95% humidity, and is panel mountable with IP54 protection. It is ideal for applications requiring robust overcurrent and fault protection in industrial electrical systems. The relay is designed for use in various environmental conditions.
The RX233 allows users to configure relay settings quickly and conveniently through Near Field Communication (NFC) with a mobile app. This unique feature streamlines installation, reduces setup time, and allows easy access to parameter adjustments, even in remote or challenging locations, eliminating the need for specialized programming tools.
With customizable three-stage overcurrent settings for each phase, the RX233 delivers precise protection that mitigates the risk of electrical faults and equipment damage. The multi-level response capability enhances system resilience by providing layered protection, helping industries maintain operational continuity and safeguard their equipment investment.
The RX233 includes extensive logging capabilities, capturing up to 120 events and recording up to 30 faults and pickups with time-stamped entries. This high level of detail empowers maintenance teams with valuable diagnostic data, enabling faster issue resolution, predictive maintenance, and improved reliability for critical electrical infrastructure.
The RX233 offers five Inverse Definite Minimum Time (IDMT) curves (DT, NI, VI, LI, EI), enabling customization for optimal coordination with other protective devices. This flexibility ensures that the relay can be precisely tailored to different electrical network configurations and response needs, making it adaptable to various industrial applications.
The self-test and soft recovery functions provide a continuous assessment of the relay’s health, automatically detecting internal issues and allowing the relay to recover from minor faults. This feature minimizes unplanned downtime and ensures that the RX233 remains operationally ready, significantly enhancing system reliability in demanding environments.
Designed to operate in temperatures from -10°C to 55°C and with humidity levels up to 95%, the RX233 is engineered for industrial durability. Its IP54-rated enclosure protects it against dust and moisture, making it suitable for rugged applications where reliability and longevity are essential. This design minimizes the risk of environmental damage, reducing the need for frequent replacements or repairs.
