Hager ECP302C Three-Phase Energy Meter for 1A or 5A Current Transformers, 4-Module DIN Rail, S0 Pulse Output

Accurate energy billing in commercial and industrial installations demands a meter that can work with external current transformers. The Hager ECP302C is a three-phase energy meter designed for indirect measurement with 1A or 5A transformer secondary currents, providing reliable data for sub-billing and energy management.

Who is it for

Electrical contractors, facility managers, and building owners who need to monitor or bill energy consumption in three-phase systems where direct connection is not possible. It suits distribution boards and control panels where current transformers are already installed.

Main features

• Indirect three-phase measurement via current transformers with 1A or 5A secondary
• MID certified for billing purposes (Class B accuracy for active energy)
• Clear LCD display with 6+2 digits, showing up to 999999.99 kWh
• S0 pulse output for integration with energy management systems
• Compact 4-module DIN rail housing (72 mm width)

Specifications

• Nominal voltage: 3x230/400 V AC
• Frequency: 50/60 Hz
• Maximum current (measurement circuit): 6 A
• Minimum current: 0.02 A
• Starting current: 0.02 A
• Pulse rate: 1000 imp/kWh (configurable)
• Operating temperature: -25°C to +55°C
• Protection class: IP20
• Mounting: DIN rail (EN 60715)

Tips

Ensure the current transformer secondary current matches the meter setting (1A or 5A). For accurate billing, use Class 0.5 or better current transformers. The S0 output can be connected to a data logger or building management system for remote monitoring.
