Product FAQs
5 answersWhat is the trip curve for the M9F22208 circuit breaker?
The M9F22208 features a C-curve trip profile, meaning the magnetic trip is calibrated to activate between 7 and 10 times the 8A rated current. This makes it suitable for general-purpose loads and control circuits with moderate inrush currents.
Can the M9F22208 be used for primary branch circuit protection?
No, the M9F22208 is a UL 1077 recognized supplementary protector. It is designed to provide additional, localized overcurrent protection within industrial control panels or equipment and must be backed up by a UL 489 listed branch circuit device.
How much DIN rail space does the M9F22208 require?
This 2-pole Multi9 C60SP breaker requires 36mm of width on a standard 35mm DIN rail, which equates to two standard 18mm module pitches.
Is the M9F22208 rated for DC control circuits?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for DC applications. It provides up to 10kA of short-circuit interrupting capacity at 125V DC.
What is the ingress protection rating of the M9F22208?
The M9F22208 has an IP20 degree of protection on its terminals, meaning it is protected against solid objects larger than 12.5mm but offers no protection against moisture. It must be installed in an appropriate DIN rail enclosure or control panel.
