Product FAQs
7 answersWhat is the trip curve for the M9F21208 circuit breaker?
The M9F21208 features a B-curve trip characteristic, which is designed to trip between 3 and 5 times the rated current. This makes it ideal for protecting resistive loads or circuits with very low inrush currents.
What wire size is accepted by the terminals on the M9F21208?
The tunnel terminals on this Multi9 C60SP breaker accept copper wiring ranging from 18 AWG to 8 AWG.
Does the M9F21208 require a specific mounting rail for installation?
Yes, this miniature circuit breaker is designed to clip directly onto a standard 35mm symmetrical DIN rail. It is not compatible with standard load centers or panelboards that require plug-on or bolt-on connections.
Is the M9F21208 rated as a branch circuit breaker or a supplementary protector?
The M9F21208 is a UL 1077 recognized supplementary protector. It is intended for use within appliances or electrical equipment where branch circuit protection is already provided or not required.
What type of protection does the M9F21208 provide?
This thermal-magnetic miniature circuit breaker provides protection against both short circuits and overload currents in control panels and OEM equipment.
What are the physical dimensions of the M9F21208 breaker?
The breaker measures approximately 3.19 inches in height, 1.42 inches in width, and 2.83 inches in depth. The 1.42-inch width corresponds to two standard 18mm DIN pitches.
Can the M9F21208 be used in IEC applications?
Yes, in addition to its UL 1077 recognition, this breaker complies with IEC/EN 60947-2 standards for industrial applications.
