C8 - Polyphase induction electricity meters

C8 - 7.jpg

C8 - 5.jpg

Watt-hour meters for the measurement of alternating current electrical energy in three-phase four-wire circuits
Watt-hour meters for two-phase three-wire circuits (meter B8kd)
Watt-hour meters assembled in DIN or BS cases made of thermoplastic material
Var-hour meters for three-wire and four-wire circuits
Watt-hour meters with pulse output device (option) enable conversation of measured energy into proportional number of electrical impulses. These impulses can be received by energy and power registers or other devices designed to cooperate with passive output of the meter.

Watt-hour meters with single- or two-rate registers and time switch built-in terminal cover
Watt-hour meters equipped with electronic maximum demand unit
