Schneider Electric METSECT5CC020 Current Transformer (200/5, DIN-rail)

Schneider · METSECT5 Series · Current Transformer · 200/5A · In stock

The METSECT5CC020 is a Schneider Electric METSECT5 series measurement current transformer with a 200/5A ratio, 5VA class-1 burden and 600V insulation. It is a ring-type (through-primary) CT designed for DIN-rail or panel mounting inside LV switchboards, MCCs and power-monitoring cabinets. KOEED stocks METSECT5CC020 alongside the full Schneider METSECT5 family for sub-metering, multi-circuit load monitoring and PowerLogic / ION / Sepam integration in industrial automation.

The CC020 suffix identifies the 200/5A ratio within the METSECT5 lineup. Use it when a feeder or branch circuit needs to be stepped down to a safe 5A secondary for an energy meter, power monitor or protection relay. KOEED also supplies the wider Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Yaskawa, Panasonic and KEYENCE ranges when a Schneider METSECT5CC020 is being deployed inside a multi-brand panel.

Key Technical Specifications & Overview

Application Scenarios & Where It Fits

METSECT5CC020 is a general-purpose 200/5A measurement CT. Schneider's METSECT5 family is purpose-built for energy and load monitoring rather than protection, so it is the right choice when the secondary feeds a kWh meter, multi-function power meter or building-management gateway instead of a trip relay.

• Sub-metering of a single 200A branch (HVAC feeder, lighting panel, machine line) inside a factory automation switchboard.
• Multi-circuit load monitoring in LV motor control centres and power distribution boards, where one CT per outgoing way feeds a Schneider PowerLogic PM or ION meter.
• Building management system (BMS) integration for tenant sub-billing, ISO 50001 energy reporting and demand-side management.
• Industrial feeder monitoring in plants mixing Schneider Modicon PLCs with Allen-Bradley ControlLogix or Siemens SIMATIC S7 controllers over Modbus / Ethernet.
• Data-centre PDU and UPS input metering, typically paired with Schneider Easergy or third-party multi-function meters.
• Renewable / microgrid tie-in monitoring, where PV or genset feeders need a clean 5A secondary for revenue-grade metering.
• Replacement of older Telemecanique / Merlin Gerin CTs in legacy switchboards, where the form-fit-function of METSECT5CC020 shortens retrofit time.

Integration & Wiring Notes

The primary passes straight through the CT window — the conductor is the primary turn, so the 200/5A ratio is fixed by the part number. The secondary is the two terminals on top of the housing, marked S1 / S2. Wire polarity matters when the CT feeds a multi-function meter that calculates power, energy or power factor, not just current.

• Observe S1 / S2 polarity. Reversing the secondary of a phase-A CT in a three-meter setup can give negative kWh and inverted power factor. KOEED always labels S1 in the wiring diagram shipped with the CT.
• Always short-circuit S1 / S2 before loosening the secondary wires. An open secondary on a CT with primary current flowing can develop thousands of volts and destroy the meter input or pose a safety hazard.
• Use 2.5 mm² copper secondary cable, run as a twisted pair, and keep the loop short. Long secondary runs increase burden and reduce accuracy class — aim for < 5–10 m to the meter.
• Ground one side of the secondary (typically S2) at the meter end. This provides a defined reference for transient over-voltage and is required by IEC 61869-2 installations.
• Match CT polarity and phase sequence to the meter's wiring diagram. Schneider PowerLogic PM5560, PM8000 and ION 8650 use the convention S1 = k, S2 = l — verify in the meter's wiring guide before energising.
• Pair METSECT5CC020 with a meter that has 5A nominal CT inputs. If the meter accepts only 1A or Rogowski inputs, pick a different METSECT5 suffix or use a Schneider iEM3000 / PM series with 5A CT input.
• When integrating with non-Schneider systems — e.g. Mitsubishi MELSEC energy modules, Omron SYSMAC power monitors or KEYENCE data loggers — confirm the meter accepts a 5A secondary and that scaling is set to ratio 40:1.
• Keep CT secondary wiring well away from VFD power cables and switching contactors. CTs sit on the same DIN rail as the breaker, but the secondary twisted pair should not share the tray with the primary conductors.

Installation & Commissioning Tips

METSECT5CC020 snaps onto a standard 35 mm DIN rail next to the breaker it monitors. The through-primary design means the feeder cable passes through the CT window before terminating at the breaker lug — no need to break the conductor to install. Once the primary is in place, the secondary wires land on finger-safe screw terminals.

• Confirm the primary conductor size fits the CT window aperture. METSECT5CC020 is sized for typical 200A feeder cable or 25×10 mm copper bar — for larger busbars, move to the next METSECT5 size up.
• Mount the CT before terminating the primary, so the cable glides through the window without nicking the insulation.
• Observe the P1 / P2 (or arrow / load-side) marking on the CT body. P1 must face the source / supply side, P2 the load — this preserves correct polarity for kWh metering.
• Torque the secondary terminals to the value printed on the housing (typically 1.2 N·m for 2.5 mm² wire). Loose terminals are the most common commissioning defect.
• Before energising, do a polarity test: with the breaker open, inject a known test current from a CT tester through P1, then verify that the meter sees the expected positive kW on each phase.
• After energising, validate the ratio: read the secondary current with a clamp meter, multiply by 40 (for 200/5) and compare to the primary clamp-meter reading. Expect < 1% error at 20–120% of rated primary current.
• If the meter shows negative active power on a phase, swap S1 and S2 at the CT terminals (not at the meter end) and re-test.
• For a multi-brand cabinet mixing Fanuc CNC, Yaskawa servo drives and Schneider switchgear, lay out the CTs on a dedicated DIN rail row above the drives to keep CT wiring away from VFD-induced noise.
• Label every CT at the panel with a unique ID matching the wiring diagram and the meter channel — this saves hours during FAT / SAT and during future AI-assisted diagnostics.
