Product FAQs
8 answersWhat is the trip curve for the M9F23332 circuit breaker?
The M9F23332 features a D-curve trip characteristic. The magnetic trip is set between 10 and 14 times the rated current, making it ideal for loads with high inrush currents such as motors, transformers, and solenoids.
Is the Schneider Electric M9F23332 rated for branch circuit protection?
No, the M9F23332 is a UL 1077 recognized supplementary protector. It is designed to provide additional protection within appliances or electrical equipment where branch circuit protection is already provided or not required.
How much DIN rail space does the M9F23332 require?
This 3-pole miniature circuit breaker is 54mm wide, which occupies six standard 9mm pitches on a 35mm DIN rail.
Is the M9F23332 part of the C60N or C60SP series?
The M9F23332 is a Multi9 C60SP series supplementary protector. It is specifically designed for multi-standard OEM equipment and industrial control panels.
What is the IP rating of the M9F23332 breaker?
The breaker has an IP20 degree of protection on its terminals, which increases to IP40 when installed in a modular enclosure.
Which auxiliary contacts and shunt trips are compatible with the M9F23332?
The breaker accepts Multi9 M9A series field-installable electrical auxiliaries. Common add-ons include the M9A26914 (OF auxiliary contact), M9A26917 (SD fault contact), and M9A26948 (MX shunt trip release).
What is the difference between the M9F23332 and standard Square D QO breakers?
The M9F23332 is a DIN rail-mounted supplementary protector designed for global OEM equipment and control panels, whereas QO breakers are plug-on or bolt-on branch circuit breakers designed for North American load centers and panelboards.
Does the M9F23332 require a specific type of DIN rail for installation?
It is designed to clip directly onto a standard 35mm symmetrical DIN rail, which is the industry standard for industrial control panels.
