3P/4P Current Transformer Module With Voltage Output

DANGER
Do not use the current transformer module if the operating voltage of the system exceeds 500 Vac, even if the insulation voltage (Ui) of the circuit breaker or switch-disconnector is indicated as being higher. Failure to follow these instructions will result in death or serious injury.

Introduction

The current transformer module with voltage output (CT+V module) provides voltage measurements to metering devices. They can be used with the following MID (Measuring Instrument Directive) power meters, to calculate energy consumption for the purposes of billing:

Power meter	Accuracy class	Communication port	Outputs	Inputs	Additional features
PM5111	0.5	1 serial port with Modbus protocol	1 digital	–	–
PM5331	0.5	1 serial port with Modbus protocol	2 digital + 2 relay	2 digital	–
PM5341	0.5	1 Ethernet port with Modbus TCP protocol	2 digital + 2 relay	2 digital	–
PM5561	0.2	2 Ethernet ports with Modbus TCP protocol	2 digital	4 digital	–
PM5661	0.2	2 Ethernet ports with Modbus TCP protocol	2 digital	2 digital + 2 RCM	–
PM5761	0.2	2 Ethernet ports with Modbus TCP protocol	2 digital	2 digital + 2 RCM	Voltage sag and swell detection with waveform capture (WFC)

WARNING
hazard of Fire The circuit breaker or switch-disconnector rating must not be higher than the current transformer rating. Failure to follow these instructions can result in death, serious injury, or equipment damage.

NOTICE
hazard of reduced accuracy The current transformer rating must not be higher than the circuit breaker or switch-disconnector rating. Failure to follow these instructions can result in loss of accuracy.

The CT+V module is suitable for use on a ComPacT NSX circuit breaker or switch-disconnector, or a ComPacT INS switch-disconnector.

Installation

WARNING
Hazard of Fire It is forbidden to install the current transformer module with voltage output in any of the following configurations: Upstream of the ComPacT NSX device or ComPacT INS switch-disconnector Downstream of the ComPacT NSX circuit breaker associated with a ComPacT INS switch-disconnector Downstream of a VigiPacT Add-on or VigiPacT Add-on Alarm With ComPacT NSX DC device Downstream, on a plug-in base equipped with connection adapter for base Downstream, on a plug-in base with rear connections LV429276. (Installation is allowed on plug-in version with power connection kit LV429269) Downstream of a PowerTag M250 Downstream of an LV429358 or LV429359 coupling accessory Upstream of an LV429358 or LV429359 coupling accessory On a ComPacT NSX 3P circuit breaker associated with a 4P current transformer module On a ComPacT NSX 4P circuit breaker associated with a 3P current transformer module On a ComPacT INS 3P/4P switch-disconnector associated with a 3P current transformer module Failure to follow these instructions can result in death, serious injury, or equipment damage.

WARNING

Hazard of Fire

It is forbidden to install the current transformer module with voltage output in any of the following configurations:

Upstream of the ComPacT NSX device or ComPacT INS switch-disconnector
Downstream of the ComPacT NSX circuit breaker associated with a ComPacT INS switch-disconnector
Downstream of a VigiPacT Add-on or VigiPacT Add-on Alarm
With ComPacT NSX DC device
Downstream, on a plug-in base equipped with connection adapter for base
Downstream, on a plug-in base with rear connections LV429276. (Installation is allowed on plug-in version with power connection kit LV429269)
Downstream of a PowerTag M250
Downstream of an LV429358 or LV429359 coupling accessory
Upstream of an LV429358 or LV429359 coupling accessory
On a ComPacT NSX 3P circuit breaker associated with a 4P current transformer module
On a ComPacT NSX 4P circuit breaker associated with a 3P current transformer module
On a ComPacT INS 3P/4P switch-disconnector associated with a 3P current transformer module

Failure to follow these instructions can result in death, serious injury, or equipment damage.

The CT+V module is mounted directly on the bottom side of the circuit breaker or switch-disconnector.

For more information about installation, consult the instruction sheet on the Schneider Electric website: GHD1633907 3P/4P Current Transformer Module With Voltage Output.

Connection

Thanks to its integrated design, the CT+V module does not require any specific wiring and is compatible with the same connection accessories as the device it is mounted on.

DANGER
Hazard of Electric Shock, Explosion or Arc Flash The jumpers I1-I2, I2-I3, and I3-S2 (1) must remain in position when the metering device is not connected. Failure to follow these instructions will result in death or serious injury.

NOTICE
Hazard of equipment damage Do not power the metering device with the voltage output from the current transformer module. Failure to follow these instructions can result in equipment damage.

Refer to the metering device documentation for more information about its installation and use.

(1) Terminals I1, I2, I3, and S2 with jumpers, if not connected to a metering device
(2) Voltage output protected against short-circuit with automatic reset
