Toroidal transformer Abb CT1M-3, reliable measurement of network currents
The ABB CT1M-3 400/5A toroidal transformer is designed for the transformation of high primary currents into standard secondary currents of 5 Amperes, allowing indirect measurement of the main electrical parameters of the network through measuring instruments, meters, and monitoring systems.
It is part of the CT1M range, a line of current transformers developed to ensure precision, safety, and reliability in industrial and tertiary applications.
Regulatory compliance and accuracy
The device complies with the IEC 61869-2 standard, the international reference for measuring current transformers.
The accuracy class ±0.5% ensures accurate and stable measurements over time, while the current limit function FS 5 protects connected instruments in case of overcurrent, enhancing system safety.
Installation versatility
The CT1M-3 transformer is suitable for use with cable or horizontal bar, making it extremely flexible for installation in distribution electrical panels. It supports cable sections up to 26 mm and bars with a nominal section of 30×10 mm or 25×15 mm, covering most standard applications.
Compact design for electrical panels
The reduced dimensions allow easy integration even in confined spaces. The IP20 protection rating makes it suitable for installations inside protected electrical panels.
Typical applications:
-
TV and Smart TV
-
Monitors and projectors
-
Decoders, Blu-ray players, and media players
