Product FAQs
8 answersWhat is the trip curve for the M9F23320 circuit breaker?
The M9F23320 features a D-curve trip characteristic. It is designed to trip instantaneously at 10 to 14 times the rated current, making it ideal for high inrush current applications like motors and transformers.
Is the Schneider Electric M9F23320 rated as a branch circuit breaker?
No, the M9F23320 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.
What types of applications is the M9F23320 breaker suitable for?
As a D-curve supplementary protector, it is commonly used in OEM control panels, industrial automation systems, and equipment with high inrush currents such as HVAC machinery and control transformers.
How much DIN rail space does the M9F23320 3-pole breaker require?
This Multi9 C60SP breaker requires 54mm of DIN rail space, which is equivalent to six 9mm pitches.
What type of wire connections does the M9F23320 accept?
The breaker features tunnel-style screw clamp terminals designed for secure connections in modular installations. The lugs accept wire gauges from 18 AWG up to 4 AWG.
Can auxiliary contacts or shunt trips be added to the M9F23320?
Yes, the Multi9 C60SP series supports field-installable electrical auxiliaries, including shunt trips (MX) and auxiliary contacts (OF), for remote tripping and fault indication.
What is the mechanical and electrical durability of the M9F23320 breaker?
The breaker is rated for up to 20,000 mechanical cycles and 10,000 electrical cycles, ensuring reliable long-term operation in industrial environments.
What is the ingress protection rating for the M9F23320 terminals?
The terminals have an IP20 degree of protection per IEC 60529, which upgrades to IP40 once installed in a modular enclosure.
