Description
Built for commercial and industrial environments, this 3A supplementary protector safeguards sensitive equipment against overloads and short circuits. The 2-pole breaker utilizes a D-curve thermal-magnetic trip mechanism to accommodate high inrush currents without nuisance tripping. It installs quickly onto standard DIN rails within OEM control panels. Rated at 10kAIC at 480Y/277VAC, the M9F23203 is UL 1077 recognized and supports optional accessories like shunt trips and alarm switches.Specifications

Product FAQs
7 answersWhat is the trip curve for the M9F23203 circuit breaker?
This breaker features a D-curve trip profile. D-curve devices are designed to trip between 10 and 14 times the rated current, making them suitable for high inrush applications such as motors and transformers.
Is the Schneider Electric M9F23203 rated as a UL 489 branch circuit breaker?
No. The C60SP series, including the M9F23203, is recognized as a UL 1077 supplementary protector. It is designed to provide additional protection within equipment or appliances where branch circuit protection is already provided or not required.
How much space does the M9F23203 occupy on a DIN rail?
This 2-pole breaker requires 36 millimeters of space on a standard 35-millimeter DIN rail, as each pole is 18 millimeters wide.
What type of terminals does the M9F23203 use for wire connections?
It is equipped with tunnel-style screw clamp terminals that accept wire gauges from 18 AWG to 4 AWG.
How does the magnetic tripping limit differ when using the M9F23203 in DC applications?
While the AC magnetic tripping limit is 12 times the rated current, the DC magnetic tripping limit is higher at 17 times the rated current, plus or minus 20 percent.
What standards does the M9F23203 comply with for global applications?
As part of the Multi9 C60SP series, it is a multi-standard device that complies with UL 1077, IEC 60947-2, GB 14048.2, and CSA C22.2 No 235.
Can auxiliary contacts or shunt trips be added to the M9F23203?
Yes, the Multi9 C60SP series supports optional field-installable auxiliaries, including state and tripping indication contacts, shunt trips, and undervoltage releases. These modules mount on the left side of the breaker without requiring tools.
