BJ-194J-9SY Smart Power Manager
BJ-194J combines high-end multifunction power meter and fire alarm system. It is the ideal choice for monitoring and controlling of power distribution systems user can reduce redundancy protection device with temperature sensor and selectable protection function can reduce the losses brought about by electrical fire.

With its four direct access keys and LCD displays helps you use all the parameters in 3P3W or 3P4W LV installation.
