Square D C60SP Multi9 Miniature Circuit Breaker (MCB)

The Square D C60SP Multi9 Miniature Circuit Breaker (MCB) is a low voltage circuit protection device engineered for control panel and industrial electrical systems. This 1P circuit breaker delivers a 2A rated current with a B tripping curve, providing a rated short-circuit breaking capacity of up to 3kA at 415VAC per EN/IEC 60947-2, along with 10kA (UL 1077) and 10kA (IEC/EN) breaking ratings. It carries UL 1077, CSA C22.2 No 235, EN/IEC 60947-2, and GB 14048.2 approvals, making it suitable for OEM panel builders and end-user installations alike.

Key Features

  • Pole & Curve Configuration: 1P (single pole), 2A rated current, B tripping curve for precise overcurrent protection.
  • Breaking Capacity: Up to 3kA at 415VAC (EN/IEC 60947-2); 10kA (UL 1077); 10kA (IEC/EN) for reliable fault interruption.
  • Rated Operational Voltage (Ue): 415V AC 50/60Hz, 240V AC 50/60Hz, and 60V DC for flexible network compatibility.
  • Insulation & Impulse Withstand: Rated insulation voltage (Ui) of 500V AC and rated impulse withstand voltage (Uimp) of 6kV.
  • Degree of Protection: IP40 in modular enclosure and IP20 per IEC 60529 for enclosure safety.
  • Terminal Connections: Tunnel-type terminals, top or bottom, accepting 1-25 mm² (AWG 18...AWG 8) rigid conductors with a 14mm wire stripping length and 2.5-2.5 N.m tightening torque.

Square D M9F21102 – Frequently Asked Questions

1) What does the B trip curve on this 2A Multi9 breaker mean for motor or transformer loads?
B curve trips on the fast side, so the M9F21102 at 2A suits resistive and electronic control loads, instrument circuits, and wiring protection where inrush is small. Motors, control transformers, and switch mode power supplies draw a heavy momentary inrush and will nuisance trip a B curve at 2A. For those, step up to a C or D curve device in the same family rather than oversizing the amperage.
2) What short circuit rating does the Square D C60SP 2A breaker have?
Breaking capacity is 3kA at 415VAC under EN/IEC 60947-2, with 10kA ratings under UL 1077 and under IEC/EN. Check the rating your application references, because the 415V number and the UL number are not the same figure.
3) What voltages can I use the C60SP Multi9 MCB on?
Rated operational voltage covers 415V AC 50/60Hz, 240V AC 50/60Hz, and 60V DC. Rated insulation voltage is 500V AC with a 6kV impulse withstand. Note it is a single pole device, so on DC the 60V figure is the limit for that one pole.
4) What wire size do the terminals on the Square D M9F21102 take, and what is the torque spec?
Tunnel type terminals, top or bottom feed, accept rigid conductors from 1 to 25 mm2, which is AWG 18 through AWG 8. Strip 14mm of insulation and torque the terminal screws to 2.5 N.m. That range means the same breaker lands anything from small control wiring up to a feeder tail into the panel.
5) How much DIN rail space does this Multi9 breaker take up in my panel?
The C60SP has an 18mm connection pitch between devices, which is the standard single module width, so one pole of this breaker occupies one 18mm module on the rail. Budget rail length accordingly when laying out a row of poles.
6) Can this breaker be locked out for maintenance, and can I see whether the contacts are open?
Yes on both. The C60SP is padlockable for lockout/tagout and has a local ON/OFF signalling indication with a contact position indicator, so an electrician can confirm the contacts are actually open before working the circuit.
7) Is the Multi9 C60SP rated for use in a wet or dusty location?
Protection is IP40 when mounted in a modular enclosure and IP20 per IEC 60529 at the device itself. That is finger safe, not weather or dust tight, so it belongs inside a control panel or enclosure rated for the environment, not exposed.
8) How many operations is the Square D C60SP good for if it gets switched daily?
Mechanical durability is 20,000 operating cycles, with a 15 year average life duration. If the breaker is being used as a routine on/off switch for equipment rather than as protection only, work that daily count against 20,000 to judge service life.
9) Does the Square D M9F21102 meet RoHS and sustainable procurement requirements?
It is RoHS EUR compliant and in scope for China RoHS, free of mercury and toxic heavy metals, WEEE product category 5, with a stated total lifecycle carbon footprint of 10 kg CO2 eq. Packaging is recycled cardboard with no single use plastic, which helps on institutional and green procurement specs.
