Single-phase energy consumption meter QOLTEC 50899 230 V 50 Hz, 5(60)A, Class 1.0, LCD

Single-phase QOLTEC 50899 energy consumption meter for 230 V systems with LCD display. Designed for monitoring active energy in single-phase installations, it operates at 50 Hz with a nominal current range of 5(60) A, accuracy class 1.0 and a low starting current of 0.4% Ib. The compact DIN-rail style enclosure (83 × 35 × 66 mm) and lightweight construction (109 g) suit household and light commercial electricity measurement and billing.

Advantages

The meter provides class 1.0 measurement accuracy for reliable energy readings and an LCD display for clear consumption data. Its low starting current enables detection of small loads, while the standard single-phase and 230 V compatibility ensures easy integration into typical residential electrical panels. Compact dimensions and DIN-rail form factor simplify installation in constrained distribution boards.

Suitable for

• Household electricity monitoring and billing
• Small commercial or office energy measurement
• Sub-circuit metering on DIN-rail distribution boards
