For protection of Ex e and Ex d motors
Protects cables and plant equipment
Adjustable thermal overload release, phase failure sensitive
Electromagnetic instantaneous release
Robust enclosure made of glass fibre reinforced polyester resin
Optionally with
undervoltage release
shunt release
ammeter
auxiliary contacts
Motor protection circuit breakers of Series 8527 are used where high short circuit currents are to be controlled and to protect both Ex e and Ex d motors. These switches are suitable to protect cables and the installation and can basically be used without a back-up fuse at 400 V. Breakers are operated by rotary handles enabling next to secure switching also to identify clearly switch settings.
