Solid-core, busbar, split-core, and summing current transformers for switchgear metering and protection
Accurate power metering, energy management, and overcurrent protection require high-precision current transformers that step down high primary busbar currents to standardized 5A or 1A secondary signals. Nairobi Power Engineers supplies the full line of Lovato Electric DMK series current transformers.
Available in solid-core ring types, rectangular busbar pass-through windows, and easy-install split-core configurations, our CTs feature Class 0.5, Class 0.5s, and Class 0.2s measurement accuracy, sealable terminal covers, and robust flame-retardant housings.
Lovato DMK • Busbar / Cable
Precision solid-core CTs with integrated busbar clamps and DIN-rail mounting accessories, certified for accuracy Class 0.5 and Class 0.2s.
Retrofit • Split-Core Clamp
Clamp-on split-core CTs with push-latch magnetic cores allowing fast installation around existing live conductors without cable unbolting.
