Product Profile

The Bulletin 825-P Modular Protection System for motors

offers a compact, modular design that uniquely allows an

installer to configure a devices functional capabilities to

match the application requirements. Flexibility is also afforded

by accommodating future expansion of the system as the

application requirements grow. Ease of installation is

provided through pluggable options and accessories. Finally,

this next generation design offers greater capabilities with

the option of full metering for line voltage and power

monitoring in addition to expanded RTD monitoring.
