Neilsen Kuljian

We offer current transformers (CTs) for use with power transducers, panel meters, and in two-piece installations with transducers and switches to extend ranges for high amperage/large conductor applications.

Agency approved & 5 A secondary ratios available from 50 A to 3000 A and higher.

NK Technologies CT-MS & CT-LS Series 1 A & 5 A Secondary Current Transformers Distributors

CT-MS & CT-LS Series

These current transformers provide an easy-to-install method to measure AC current, producing a 0-1 A or a 0-5 A output proportional to the current flowing through the sensing window. Both the CT-MS and the CT-LS series offer a larger-than-average sensing window and a split-core design for easy installation.

A current transformer (CT) should never be energized (AC current through the sensing window) without a load connected to the output terminals. Best practice is to terminate the current transformer secondary on a terminal block with the ability to short between two points before extending the leads to the load. If it is ever necessary to remove the load from the CT while it is or could become energized, a shorting bar can be placed between the secondary loads, as shown in the drawing to the right. This will allow the load to be removed safely.

NK Technologies ProteCT Series mV Current Transformers Distributors

ProteCT Series mV

ProteCT Series Current Transformers are intended for use with APT and APO/APN series power transducers.

ProtectCT low voltage output current transformers provide easy sensing of current on three-phase applications with the added safety of a 333mV output secondary.

Available in split-core packaging as standard.

Unique low voltage output allows safe opening of transformer secondary, protecting installers from shock hazards found on traditional 5 A CTs.

NK Technologies 5Amp Secondary Current Transformer Distributor

5 A Secondary

5Amp secondary current transformers offer a compact, cost-effective means of measuring primary current.

NK Technologies 5A secondary current transformer provides 0-5A secondary output proportional to the primary current being sensed.

Available in solid-core or split-core enclosures.

Serves as current input for use with APT and APN Series KW transducers.

Save space in control panels by remotely locating CTs closer to load. 5 A secondary compatible with standard products offering a 5 A analog input option. Broad line accommodates primary currents from 50 A to 3000 A.

NK Technologies CTRC Series ProteCT Type 333 mVAC Output AC Current Transformers Distributors

CTRC Series

CTRC AC Current Transformers monitor circuits up to 2000A and produces a safe, low voltage output proportional to the RMS current value. This output is designed as an input to a power monitor or transducer, replicating the AC wave shape with phase angle resolution better than 2 degrees. The flexible coil design allows the sensor to be installed over multiple conductors or bus assemblies easily, and the cable requires very little space to fit between adjacent phase conductors.

IDEC Relays

Installation Time is greatly reduced with pre-assembled relays and sockets. Replacement relays and sockets are also available. Optional accessories include jumpers, spacers and marking plates to facilitate wiring and quick identifications. Jumper combs come with 20 points, if shorter lengths are needed simply cut off the excess points. Note: When using a cut jumper, please use a spacer on the cut side.

SymCom Monitor

The Model 455-480R, 3-phase voltage monitor combines line and load-side monitoring to alert the user of contactor failure. Line-side monitoring will protect the motor from damaging power conditions including high and low voltage, voltage unbalance, single-phasing, phase reversal and rapid cycling. The Model 455-480R has a high voltage relay to handle up to 600V control voltage and is now equipped with an
