Product code: SG-METER-125H
It is a multifunctional and compact analyzer for use in three-phase systems with three or four wires and unbalanced load.
It is a multifunctional, compact analyzer for use in three-phase systems with three or four wires and unbalanced load. It allows the visualization of the main of an electrical network, including counts of active and reactive energy bidirectional. To reduce costs and wiring time, it is equipped with a current input of 125A. The TA triple miniature is included. The TA has compact dimensions and it is compatibilie with center distance of modular switches. Therefore it can be mounted even in conditions of very reduced space, both upstream and downstream of the circuit.
TRANSFORMER OF SG-METER-125H
The constructive characteristics of the current transformer are: small size, large diameter of the through holes, spacing compatible with that of the switches modulari.Quindi is possible to install it in proximity switch, both upstream and downstream of the same, even where the space available is extremely low. In addition, it is equipped with integrated connecting cable (length 1.5 meters) and, if necessary, it is possible to fix it directly on the central cable through the integrated fixing bracket and the clamp. The indelible markings indicate the phases (L1, L2, L3) and the mounting position respect to the direction of the primary current (P1). They have been designed considering some important aspects for the installer such as convenience, speed of installation, miniaturization. It is a product that can be used in all cases in which you do not have the space required for the installation of the classic current reducers individual. Allows you to measure currents up to 125 A.
It is equipped with RS485 ModBus RTU communication module.
