Product FAQs
6 answers
What does the B-curve trip profile mean for the M9F21213?
The B-curve thermal-magnetic trip profile means the magnetic trip is calibrated to operate between 3.2 and 4.8 times the 13A rated current. This makes it ideal for protecting resistive loads, PLCs, or circuits with very low inrush currents where a standard C-curve might not trip fast enough.
Is the M9F21213 rated as a primary branch circuit breaker?
No, the M9F21213 is part of the Multi9 C60SP series, which is UL 1077 recognized as a supplementary protector. It is designed to provide additional protection within appliances or electrical equipment where branch circuit protection is already provided upstream.
What electrical accessories are compatible with this breaker?
The M9F21213 is compatible with Schneider Electric Multi9 electrical auxiliaries. This includes shunt trips (MX), undervoltage releases (MN), auxiliary contacts (OF), and fault indicating contacts (SD), which mount directly to the left side of the breaker.
Can the M9F21213 be reverse fed?
Yes, like most Schneider Electric Multi9 miniature circuit breakers, the M9F21213 supports reverse feeding. The line and load connections are not restricted to specific top or bottom terminals, allowing for flexible panel wiring.
What is the recommended terminal tightening torque for this breaker?
The screw clamp terminals on the M9F21213 should be tightened to 22.12 lbf.in (2.5 N.m) for secure and safe wire connections.
What standards does the M9F21213 comply with for international use?
As a multi-standard product, the M9F21213 complies with UL 1077, CSA C22.2 No 235, EN/IEC 60947-2, and GB 14048.2. This makes it suitable for OEM equipment and control panels destined for global markets.
