Three Phase Four Wires Din Rail Energy Meter DRT-301A

Model: DRT-301A (3P4W)
Name: Three Phase Four Wires Din Rail Energy Meter DRT-301A
Introduction: Three phase,7 modules,126 mm,100A direct or CT 1.5(6)A indirect,50~60Hz, 230/400V AC (3~),Register display, DIN rail.

l The DRT-301A is three phase kWh meters with a register display in a 7 modules (126mm) casing, ensuring a high accuracy class (Class1), a very low starting current which makes it exceptionally suited for photovoltaic energy systems and general use.

l Excellent long term stability which is designed for DIN, IEN and EN standards and 5 years of warranty.

l MID B&D approval which ensures the meter is produced to the highest European and International standards and the meter legally suited for business and invoicing purposes.

l The meter is available in several different versions: with or without backlight and brake, with 1600 or 400 SO output.

l For connection rate up to 100A. or connection with CT 1.5(6)A

5A CT version for measuring with current transformers available (27 CT Changing-Ratios to choose).
