Product Details
The B21 Series is a Single phase Direct connected meter for up to 65 A. The B21 measures active energy with accuracy class B (Cl.1). The low rated or base currents of the meter ensure high dynamic performance with superior accuracy even at low currents.
Navigation of the meter is easily done via the push-buttons below the display. The exceptional low power consumption of the meter, less than 0.9 VA, makes it economical in the long run - an important feature especially for large meter populations.
