Moulded Case Circuit breakers

The Ex9MD range of moulded case circuit breakers (MCCB) provide high current breaking capabilities for DC circuits.

• High breaking capacity
• Installation flexibility
• Field installable accessories
• Certified to EN 60947

DC switching voltage
250V DC per pole e.g. 2 pole = 500V DC
2 and 3 Poles models available from 80A to 800A


Circuit Breaker Enclosures

The IP65 rated enclosures from PV Power & Noark offer IP65 water ingress protection for circuit breakers.

The PV power models offer watertight wall-mounted distribution boards for domestic and industrial fitments for mounting modular equipment for protection (IP65) against water, dust and more.

Also coming soon is the brand new Noark NWPB-1 IP65 rated enclosure, which has been designed for use with the Noark molded case circuit breaker range. This unit is suitable for 2 pole MCCB's from 80A-250A and accomodates both frame sizes 1 and 2.




Miniature Circuit breakers

The Ex9BP-N series of miniature circuit breakers from Noark Electric are non polarised and available in 2 and 4 pole designs.

DC switching voltage 180V DC per pole (e.g. 4 pole = 720V DC)

Terminal Shields

The Noark terminal sheilds are a great addition to the MCCB range by offering touch protection of the terminals themselves.

With options for 2 and 3 pole MCCB's ranging from 80A to 800A, the covers provide peace of mind in any system build.
