Eastron — equipment and components

Current transformers and sensors Eastron

Specify Eastron sensors for replacement or complete measurement chains. Provide the current rating, output signal, conductor dimensions and the connected meter or analyzer model.

Current transformers and sensors

Treat the sensor and the instrument as one measurement chain. Primary current, output signal, measurement class, dimensions and connection length all matter. A photograph of the meter front does not identify the installed transformer.

Split Core Current Transformers

Split-core CTs for measurement circuits. Selection requires the aperture dimensions, conductor shape and sensor output. For an existing switchboard, include photographs showing the available space around the cable.

Solid Core Current Transformers

Solid-core current transformers. Specify the primary current, secondary signal and mechanical dimensions. Confirm that the existing assembly permits the intended mounting arrangement before ordering.

ESCT-3RJ (3-in-1)

A three-phase 3-in-1 sensor with RJ connection and mA/mV output for the Easy Click System. For replacement, compare conductor spacing, cable type and the intended measurement input.

ESCT-RC Type A / Type B

Flexible Rogowski coils with an 8 mm cross-section. Type B lists 85/50/100 mV/kA at 50 Hz; Type A lists 85/50 mV/kA. Specify the loop length and match the output to the receiving instrument.

Integrators for Rogowski Coil

Eastron lists integrators as a separate product group. Selection needs the coil output, required converted signal and power supply. State whether the measuring instrument already includes the integration function.

ESCS

The catalog lists ESCS-E1, G1, D1, C1, B1/B2, B3 and A1 residual-current sensors for EV chargers. Provide the full suffix, mechanical drawing and the controller requirements for output signals.

Choose the equipment group

For consumption metering, start with SDM or DCM and define AC or DC operation and the connection method. Consider Smart X when the project requires network parameters and harmonic readings. If the instrument stays in place but an external sensor needs replacing, use the current-transformer group.

An ESP gateway transports data already measured by another device. The monitoring group covers projects with multiple measurement points. Time-delay and weekly-schedule tasks belong to ESRD and ESRS. This separates the required device from its function in the wider installation.

Specify an installed-device replacement

Photograph the front and side identification, terminal markings and the installation space. Transcribe the full model suffix. If the circuit includes CTs or a shunt, identify those components separately; the meter name alone does not define the complete measurement set.

State whether you need one instrument, a set with sensors or equipment for several identical panels. Describe an observed failure such as a blank display, missing communication or inconsistent readings. This helps distinguish a replacement purchase from a measurement-chain investigation.

Current input, protocol and scope of supply

Separate the primary current from the signal reaching the instrument. Inputs rated at 1 A / 5 A, 40 mA, 100 mA, 100 mV and Rogowski-coil inputs require the corresponding sensors. The power-circuit current rating alone does not specify the instrument variant.

For RS485, provide the protocol, addresses, speed and communication format. For Ethernet, define the device role and receiving system. List the meters, sensors, connecting cables, converters and mounting items actually required as separate entries in the scope of supply.

Inverter and charging-station projects

For an inverter, identify the exact model, software version and meter location in the power diagram. Include the supported-device list from the inverter documentation where available. Compatibility assessment concerns the specific device pair, including registers and energy-flow direction.

For a charging station, state AC or DC operation, the working range and power connection. Add any need for a separate display or multiple communication ports. Compare market-specific variants using the complete ordering code and project documentation.

Prepare a sourcing request

Send the ordering code or photographs, required quantity and delivery destination. If identification is incomplete, include the relevant wiring-diagram section and explain the device function. For a new installation, provide a specification with a separate line for each instrument type.

The quotation should be compared with the requested variant and set contents. State whether an alternative may be proposed for engineering review. For multiple panels, distinguish the quantity per panel from the total procurement quantity.

Quotation and project confirmation

Availability, price, lead time, compatibility and included components are confirmed for the selected variant after reviewing the request. No authorized-dealer status is claimed. MID, UL/ETL or PTB/Eichrecht identification must be checked against the exact instrument and project requirements.
