Current transformer Schneider Electric METSECT5CC010, 100 A output, 720 V input, IP20, white

Schneider Electric METSECT5CC010 is a compact split-core current transformer designed for measurement and monitoring in electrical panels and distribution systems. The device provides a 100 A nominal secondary output for use with compatible meters and relays and is built to accept primary conductors up to 21 mm in diameter. The white, space-saving housing with an IP20 degree of protection fits standard panel layouts where basic touch protection is required.

Advantages

The METSECT5CC010 delivers a stable 100 A secondary current suitable for integration with energy meters and protective devices. Its split-core design allows quick installation without disconnecting conductors, while the compact footprint (44 mm width, 30 mm depth, 65 mm height) minimizes panel space usage. The unit’s construction supports straightforward handling and alignment in distribution boards, and the IP20 rating ensures protection against accidental contact in indoor electrical enclosures.

Suitable for

• Current measurement and metering in low- and medium-voltage distribution panels
• Energy monitoring and power quality systems using 100 A secondary inputs
• Integration with protection relays and control equipment in switchboards
• Retrofit installations where conductors cannot be disconnected

Key specifications

• Nominal secondary output current: 100 A
• Maximum primary input voltage: 720 V
• Primary conductor diameter capacity: up to 21 mm
• Protection degree: IP20
• Housing colour: white
• Dimensions (W × D × H): 44 mm × 30 mm × 65 mm

How to use

Open the split-core housing and place the primary conductor through the aperture, ensuring the conductor sits centrally within the core before closing the unit. Mount the transformer within the panel using recommended fastening points so it remains stable and vibration-free. Connect the secondary output to the meter or relay according to the receiving device’s wiring diagram and ensure correct polarity and secure screw or terminal connections. Verify that the primary conductor diameter does not exceed 21 mm and that the system voltage does not exceed 720 V.

Usage recommendations

Install and commission the transformer only with power off and in compliance with local electrical standards. Use appropriate metering equipment matched to a 100 A secondary. For accurate measurement, avoid placing other conductors through the core and ensure the primary conductor is centred. Keep the unit within indoor enclosures or panels where IP20 protection is sufficient; for exposed or outdoor locations select devices with higher ingress protection.
