Description
PRODUCT DESCRIPTION
Designed for measurement of RMS current and voltage (a.c.), active power and frequency. Thanks to modern design, N27D fulfills the requirements for devices mounted in standard modular switchgears.
Features:
measurement of:
RMS current (a.c.)
RMS voltage (a.c.)
active power
frequency
direct measurement up to 63A,
switched measured value,
4-digit display in yellow colour,
backlighted indicator of measured value,
modern design allows for installation of the meter in modular switchgear in accordance with EN 62208
(meter has a width of 3 modules) on 35 mm rail.
external dimensions: 53 x 110 x 60mm.
