CM52 network protector overview

Learn why Eaton's CM52 is the industry’s most modern network protector available today. This dead-front design is available with numerous arc-flash safety features. 

Designed to reduce maintenance time

Featuring four-position, draw-out, dead-front circuit breaker and standardize modular components, Eaton’s CM52 network protector helps to reduce maintenance time, lower inventory costs and simplify training for crews.

The benefits of robust legacy network protectors along with improved user and operational safety

The CM52 network protector is comprised of an enclosure assembly, breaker element and relay module. Additional features include the stacklight submersible visual indication device, VisoBlock visible break, RAD remote access device, bulkhead junctiion box, visible-break windows and quick latches.

Improved safety in the network

Eaton’s CM52 network protector allows for improved safety and more reliable protection on a network system due to higher ratings and advanced technology additions than legacy protector models.

Remote Racking (RemRack)

Eaton’s CM-52 remote racking device provides a means of remotely connecting and disconnecting a network protector from the energized buswork. This is done while the door of the network protector remains bolted shut. This device helps mitigate any chance of arc flash exposure risk while disconnecting or re-connecting.
