Current Transformer Milesight CT-101-915M — blue, cable diameter 1.6 cm, IP30, 86.5×31×37.4 mm

Milesight CT-101-915M is a compact current transformer in a blue housing designed to measure alternating current where installation space is limited. The device accepts a single conductor or cable with a maximum diameter of 1.6 cm and provides a simple, low-profile solution for integration with monitoring devices and energy meters. Its IP30 protection rating makes it suitable for indoor installations in dry, controlled environments; the unit’s external dimensions are 86.5 × 31 × 37.4 mm, allowing placement in tight enclosures or on DIN-rail mounted panels with limited clearance.

Advantages

The CT-101-915M combines compact size and straightforward functionality to provide reliable current sensing for alternating current applications. The slim form factor and small footprint reduce the required mounting space while the blue plastic housing offers basic mechanical protection. The acceptance of cables up to 1.6 cm in diameter simplifies connection to existing wiring without special adapters. Designed for ease of integration, the transformer supports common metering and monitoring workflows where a simple, passive current sensor is required.

Suitable for

• Indoor energy monitoring panels with limited space
• Integration with energy meters and data loggers
• Current sensing for HVAC, lighting circuits, and small motors
• Retrofit installations where cable diameter is up to 1.6 cm

Key specifications

• Housing color: blue
• Cable diameter capacity: up to 1.6 cm
• Protection rating: IP30 (suitable for dry indoor environments)
• External dimensions: 86.5 × 31 × 37.4 mm
• Measurement type: alternating current (AC) sensing

How to use

Install the CT-101-915M by passing the conductor or cable through the transformer aperture, ensuring the cable diameter does not exceed 1.6 cm. Mount the unit in a dry, indoor location where the IP30 rating provides appropriate protection from dust and contact. Connect the transformer’s secondary leads to the monitoring device or energy meter following that device’s input wiring diagram and safety instructions. Verify polarity and secure all connections before applying power, then confirm readings with a known reference or test load.

Recommendations

For reliable long-term performance, use the CT-101-915M in indoor, climate-controlled installations and avoid exposure to moisture or heavy dust. Confirm compatibility of the transformer’s output with the input requirements of your meter or monitoring device, and use proper mounting to prevent mechanical strain on the cable and the transformer body.
