Toroidal Split Core Current Transformer / Sensor

Toroidal Split Core Current Transformer / Sensor

Model: MP
Specification: MST253, MST550, MST801, MST180

Uses a toroid-shaped split core for current sensing without detaching cables.

Main Power provides several Toroid Shape of Split Core CT.

Split Core Current Transformer / Transducer are designed to be small and easy to open and yet maintain the accuracy required for energy meters and monitoring. The benefit of a split core current transformer is that it can be placed into position easily and without removing existing cables for easier installation.

We also offer other type of CT such as Split Core Current Transformer, Zero Phase Current Transformer, AC DC Current Transformer, Window Shape Split Core Current Transformer.

The Toroidal Split Core Current Transformer / Sensor uses a round, ring, or toroid split-core design that clamps around an existing conductor without disconnecting the wire or interrupting circuit operation. It mounts by foot or busbar, giving a cost-effective, quick installation for electrical fire monitoring, leakage fire prevention, electromagnetic relay protection, and microcomputer protection.

Main Power Electric, established in 1987, is a Taiwan-based manufacturer of current sensors and transformers. It builds the Toroidal Split Core Current Transformer / Sensor (Model: MP; Specifications: MST253, MST550, MST801, MST180) under an ISO 9001 quality management system, testing 100% of samples, trials, and production components. The company runs an in-house CT laboratory, holds UL certification, and manufactures this product line at its Taoyuan, Taiwan facility, with global delivery. Accuracy class is 0.5-2% across current ratings from 5A to 5000A, delivering high-quality measurement.

Q: What specifications, shapes, and mounting choices are available for the MP Toroidal Split Core Current Transformer / Sensor?

A: Main Power Electric offers the Model MP Toroidal Split Core Current Transformer / Sensor in MST253, MST550, MST801, and MST180 specifications, in a round, ring, or toroid shape. The series covers an operating current range of 5A to 5000A at an accuracy class of 0.5-2%, and mounts by foot or busbar.

Q: How does the toroidal split-core design measure current without disrupting an existing system?

A: The split-core body clamps around an active conductor or busbar without removing existing cables or shutting down power. This lets you retrofit quickly at low cost while keeping measurement accuracy, and it is used in electrical fire monitoring, leakage fire prevention, and electromagnetic relay protection.
