SCHNEIDER XCKMR54D1H29 Miniature Circuit Breakers

Schneider Electric is a global leader in circuit protection, primarily represented by the Acti9 iC60 and Multi9 ranges. These Miniature Circuit Breakers (MCBs) are designed to protect electrical installations from overloads and short circuits while ensuring continuity of service.

Product Detailed Description

Schneider MCBs are mechanical switching devices capable of making, carrying, and breaking currents under normal circuit conditions. They automatically “trip” (open the circuit) when they detect a fault. The Acti9 iC60 series is the flagship range, known for its modular design, safety features, and high breaking capacity in a compact footprint.

Key Technical Parameters

Product Advantages

• VisiSafe: A green visible strip on the handle confirms that the downstream circuit is physically disconnected and safe for maintenance.

• VisiTrip: A red mechanical indicator on the front face identifies the faulty circuit at a glance, reducing troubleshooting time.

• Reflex iC60: An “all-in-one” concept that combines an MCB with an internal actuator, allowing for remote control and automation without extra accessories.

• Class-2 Insulation: Guaranteed safety for operators and non-qualified personnel during the entire life of the installation.

• Fast Closing: A mechanism that reduces wear and tear during closing operations, extending the electrical life of the device.

Important Considerations (Precautions)

• Curve Selection: Choose the correct curve based on the load.

  • B-Curve: Residential/lighting with low inrush.

  • C-Curve: General purpose (the most common).

  • D-Curve: High inrush loads like motors or large transformers.

• Backup & Coordination: Ensure proper “selectivity” so that a fault in a sub-branch only trips the local MCB and not the main upstream breaker.

• Terminal Torque: Use a calibrated screwdriver to tighten terminals to the specified torque (usually 2 to 3.5 N.m) to avoid loose connections and fire hazards.

• Derating: Consider ambient temperature; if the MCB is installed in a hot enclosure (above 30°C), the rated current capacity will decrease.

Product Applications

• Residential: Protecting lighting circuits, kitchen appliances, and EV charging points.

• Commercial Buildings: Power distribution for offices, HVAC systems, and shopping mall infrastructure.

• Industrial Automation: Protecting PLC power supplies, control circuits, and small motors.

• Critical Infrastructure: Data centers and hospitals where the VisiTrip feature helps restore power quickly.
