Low-voltage current and voltage transformers 600/720 V
Country: USA · Model: LV CT / VT 600/720 V
The line of low-voltage current and voltage transformers of the 600/720 V class is intended for commercial metering, switchboards and low-voltage switchgear. The 600 V voltage transformers come in single- and three-phase versions rated 40–750 VA, and the current side covers indoor, bushing-type and wide-range CTs.

Description
Indoor current transformers are installed in LV switchboards and cells where a bus or a cable passed through the window serves as the primary conductor. Bushing-type CTs are fitted over the bushing of a device, so no separate space in the cabinet is needed for them. Wide-range CTs of the Encompass and RevenueSense series are designed for commercial metering where the load varies greatly during the day, and one size covers both small and rated currents. The 600 V voltage transformers are made with built-in fuses or without them, so primary circuit protection can be taken from the VT itself or moved to a separate block. The units are built to IEEE C57.13 with UL/cUL and CSA certification, which is required for switchboards under North American codes.
How to choose
First determine what has to be measured, current or voltage. For buses or cable in a switchboard, take an indoor CT; for a device bushing, a bushing-type; and for commercial metering with a strongly varying load, a wide-range Encompass or RevenueSense. The 600 V voltage transformer is selected by the number of phases and the power within 40–750 VA, adding up the consumption of all connected instruments with a margin. Power for control circuits in the same switchgear is taken from separate control transformers of the same line.

FAQ
What power do the 600 V voltage transformers have?
From 40 to 750 VA, in single-phase or three-phase versions, with or without fuses.
What does the wide-range Encompass current transformer give for metering?
It holds accuracy over a wide range of primary current, so one unit correctly counts both small and rated loads. The RevenueSense series solves a similar task.
Which standards are these current and voltage transformers made to?
To IEEE C57.13, with UL/cUL and CSA certification for the North American market.
What voltage are the current transformers of this line rated for?
For the 600/720 V class, that is, with a margin for low-voltage switchboards and switchgear.
Where is a bushing-type current transformer installed?
On the bushing of a circuit breaker or power transformer. The bushing itself then serves as the primary conductor, and the transformer takes no space in the cell.
