Product FAQs
6 answersIs the M9F23240 rated for branch circuit protection?
No, the M9F23240 is a UL 1077 recognized supplementary protector. It is not a UL 489 listed branch circuit breaker and must be used alongside an appropriate upstream branch protection device.
What applications are suitable for the D trip curve on the M9F23240?
The D trip curve magnetically trips at 10 to 14 times the rated current. This makes it ideal for protecting circuits with high inrush currents, such as motors, transformers, and specialized industrial equipment.
What wire sizes do the terminals on the M9F23240 accept?
The tunnel terminals accept 18 AWG to 2 AWG rigid copper wire, or 18 AWG to 3 AWG flexible copper wire when using ferrules. The recommended stripping length is 14 mm.
What is the recommended terminal tightening torque for the M9F23240?
The recommended tightening torque for the top and bottom tunnel terminals is 22 lb-in (2.5 N.m).
What field-installable accessories work with the M9F23240 breaker?
This Multi9 C60SP breaker accepts standard Schneider Electric Multi9 electrical auxiliaries, including OF auxiliary contacts, SD alarm switches, MX shunt trips, and MN undervoltage releases.
