Description
Utilizing advanced Multi9 technology, this 20-amp single-pole supplementary protector ensures robust current limiting for industrial applications. The module fastens onto standard DIN rails in control panels and acts as a functional substitute for S201-B20, FAZ-B20/1, or 5SY4120-6 components. Equipped with a B-curve trip profile and a visual contact position indicator, it provides 10kA interrupting capacity at 277VAC while supporting reverse feed configurations.Specifications

Product FAQs
6 answersWhat is the trip curve for the M9F21120 circuit breaker?
The M9F21120 features a B-curve thermal-magnetic trip profile. It is designed to trip between 3.2 and 4.8 times the 20A rated current, making it ideal for protecting sensitive equipment and control circuits with low inrush currents.
Is the Schneider Electric M9F21120 rated for branch circuit protection?
No. The M9F21120 is a UL 1077 recognized supplementary protector. It is not UL 489 listed for branch circuit protection and must be used in conjunction with an appropriate upstream branch circuit breaker or fuse.
How does the M9F21120 mount inside a control panel?
This Multi9 C60SP miniature circuit breaker clips directly onto a standard 35mm DIN rail. It requires a single 18mm wide space on the rail.
Can I add auxiliary contacts or shunt trips to the M9F21120?
Yes, the Multi9 C60SP series supports field-installable electrical auxiliaries. You can add shunt trips, undervoltage releases, and auxiliary contacts that mount alongside the breaker on the DIN rail.
What size wire is accepted by the terminals on the M9F21120?
The screw clamp terminals on this 20A breaker accept copper wire ranging from 18 AWG to 4 AWG.
What is the IP rating of the M9F21120 breaker terminals?
The terminals have an IP20 degree of protection, which prevents accidental contact with live parts by fingers or solid objects larger than 12.5mm.
