Product FAQs
8 answersWhat is the trip curve for the M9F21103 circuit breaker?
The M9F21103 features a B-curve trip profile. It is designed to trip between 3.2 and 4.8 times the rated current, making it ideal for protecting sensitive electronic equipment and control circuits with low inrush currents.
Is the Schneider Electric M9F21103 UL listed as a branch circuit breaker?
No, the M9F21103 is a UL 1077 Recognized supplementary protector. It is not a UL 489 listed branch circuit breaker and must be used in applications where branch circuit protection is already provided or not required.
How much DIN rail space does the M9F21103 require?
This 1-pole miniature circuit breaker has a width of 18mm, which occupies one standard DIN rail module space.
Can I add auxiliary contacts or shunt trips to the M9F21103?
Yes, the Multi9 C60SP series is compatible with field-installable electrical auxiliaries, including OF (status) and SD (fault indication) contacts, as well as MX or MN shunt and undervoltage releases.
What is the operating temperature range for the M9F21103 breaker?
The M9F21103 is rated for operation in ambient temperatures ranging from -30 degrees C to 70 degrees C (-22 degrees F to 158 degrees F).
What is the recommended tightening torque for the terminals on the M9F21103?
The screw clamp terminals on this circuit breaker should be tightened to 22.1 in-lbs (2.5 N.m).
How much insulation should be stripped from the wire before connecting it to the M9F21103?
You should strip 14 mm (approximately 0.55 inches) of insulation from the wire for a secure connection in the top or bottom terminals.
Is the M9F21103 a direct replacement for older Schneider Electric breakers?
Yes, the M9F21103 is the direct manufacturer replacement for the legacy Multi9 C60 part number 24112.
