Product FAQs
9 answersWhat is the trip curve for the Schneider Electric M9F22308?
The M9F22308 features a C-curve trip characteristic. For AC applications, its magnetic tripping limit is set at 8.5 times the 8A rated current (plus or minus 20 percent). This is ideal for general-purpose loads with moderate inrush currents.
Is the M9F22308 rated as a branch circuit breaker or a supplementary protector?
The M9F22308 is a UL 1077 recognized supplementary protector. It is not a UL 489 listed branch circuit breaker and must be used downstream of an approved branch circuit protection device.
What wire sizes are compatible with the terminals on the M9F22308?
The screw clamp terminals on this Multi9 C60SP breaker accept wire sizes ranging from 18 AWG to 8 AWG.
What is the interrupting rating of the M9F22308 at 480Y/277V AC?
While rated for 14kA at 240V AC, the M9F22308 has a 10kA interrupting rating at 480Y/277V AC under UL 1077. Under IEC 60947-2, it is rated for 6kA at 440V AC.
Can the M9F22308 be used in DC voltage applications?
No, the M9F22308 is strictly rated for AC voltage applications up to 480Y/277V AC under UL 1077 and 440V AC under IEC standards. It does not carry a DC voltage rating.
What is the direct replacement for the discontinued Schneider Electric MG24465 circuit breaker?
The Schneider Electric M9F22308 is the direct, manufacturer-recommended replacement for the obsolete MG24465 Multi9 C60 breaker. Both are 3-pole, 8A, C-curve supplementary protectors.
Does the M9F22308 provide earth leakage protection?
No, the M9F22308 is a thermal-magnetic miniature circuit breaker designed for short-circuit and overload protection. It does not provide earth leakage or ground fault protection on its own.
How much DIN rail space does the M9F22308 require?
The M9F22308 is 54mm wide, which occupies six standard 9mm pitches on a 35mm DIN rail.
Can the M9F22308 be locked in the OFF position?
Yes, the toggle mechanism on the M9F22308 includes provisions for padlocking, allowing the breaker to be safely locked out during maintenance.
