Physical Specifications
Dimensions
Adopting ABB Relion series standard panel-mount design, the dimensions are145 mm × 145 mm × 210 mm (5.71 in × 5.71 in × 8.27 in). This compact form factor is optimized for installation in switchgear and control cabinets, enabling space-efficient integration with other power monitoring and control devices such as meters, contactors, and PLCs.
Weight
Net weight is approximately 2.5 kg (5.51 lbs) without accessories, constructed with high-strength metal housing to resist mechanical impact. Transportation weight (including original packaging) is around 4.0 kg, facilitating easy handling during on-site installation and maintenance.
Mounting & Housing
Designed for standard panel mounting (compliant with IEC 60601-1) and optional DIN rail mounting with adapter. The housing features a rugged metal structure with an IP42 protection rating for the front panel, effectively preventing dust and water splashes in industrial switchgear environments. The front panel is equipped with a 4-line LCD display and LED indicators for intuitive monitoring of operation status, fault alerts, and power conditions.
Core Features
1. Comprehensive Protection Functions: Equipped with overcurrent (50/51), earth fault (54/59N), overvoltage (59), undervoltage (27), and thermal overload protection, supporting both phase and ground fault detection with adjustable pickup values and time delays to match diverse grid configurations.
2. Advanced Measurement Capabilities: Delivers precise measurement of three-phase current, voltage, power (active/reactive/apparent), energy, power factor, and frequency with 0.2% class accuracy, providing real-time data for grid optimization and energy management.
