Physical Parameters

Dimensions: Approx. 18cm (W) × 16.5cm (L) × 21.5cm (H)

Functional Configuration

Setpoint Groups: 4 sets

Communication Interfaces: Standard RS232 (single-unit monitoring), RS422/485 (multi-unit networking), optional Ethernet port

Supporting Software: Enervista 750 (parameter configuration and data trend analysis)

IV. Key Functional Features

Protection and Control Capabilities

Supports fault monitoring and isolation for feeder systems, requiring zero-sequence current transformers (twisted-pair wiring needed to ensure accuracy in ground fault detection).

Can simulate fault and normal operating conditions by pausing actual AC signal acquisition and generating simulated data to verify parameter configuration validity.

Communication and Data Management

Multi-interface adaptability: RS232 for standalone local debugging; RS422/485 for multi-relay network monitoring.

Visual configuration, data trend analysis, and event log queries via Enervista 750 software.

Installation Flexibility

Operates standalone or clusters with other 750 series relays, adapting to distribution panel integration needs.

V. Application Scenarios

Protection and control of low-voltage distribution feeder circuits

Management of power distribution systems in industrial plants, commercial buildings, and infrastructure

Scenarios requiring flexible parameter debugging and multi-device network monitoring
