Schneider MCB 40A 2P A9K24240 Circuit Breaker is an option within the MCB automatic circuit breaker category at Bashiti Stores, designed to protect circuits from overloads and short circuits. In this version, the rated current is 40 Amperes and the number of poles is 2P. These specifications distinguish the model from other alternatives in the same series; match them with your circuit requirements and do not choose a breaker with a higher amperage just to increase the operating margin.
Practical Benefits
- Combines overload and short-circuit protection functions in a single standardized device.
- Distributing protection across independent circuits helps organize the distribution board and identify the affected circuit in the event of a fault.
- Choosing the correct current, number of poles, and tripping curve provides the basis for aligning the breaker with circuit requirements.

Who needs this product?
Electricians, wiring contractors, and homeowners or shop owners who are setting up a new distribution board or replacing a breaker matching an existing circuit. The selection depends on the circuit design, cable cross-section, and installation method, not just the device type or the appearance of the breaker.
Installation and Verification Method — For Certified Technicians
The following steps outline the general workflow; refer to the manufacturer's diagram for reference A9K24240 to determine terminals and tightening torque values. Do not perform work on a live circuit.
- The technician must disconnect all power sources, secure them against reactivation, and verify the absence of voltage with a suitable tool.
- Match the device reference, number of poles, current, and voltage with the distribution board diagram, and review conductor cross-sections and protection coordination.
- Mount the unit on the rail or its designated position after ensuring compatibility, and identify the supply and output based on the manufacturer's diagram for this reference.
- Perform the connections using the tightening torque, stripping length, and wire gauges specified in the model manual; do not copy these values from a similar device.
- Check the tightness of the installation and connections, then close the covers and conduct the required operation and protection tests before handing over the circuit.
Frequently Asked Questions Before Buying
Does this breaker protect against earth leakage?
An MCB is intended for overload and short-circuit protection and does not replace earth leakage protection. Check the need for an RCCB or RCBO within the distribution board design.
Should I replace a breaker that trips constantly with one of a higher amperage?
No. You must first determine the cause of the tripping and check the load, cable, and connections. Increasing the amperage without analysis may leave the wires without proper protection.
What is the difference between current (amps) and breaking capacity?
The amperage is the rated current of the breaker, while the breaking capacity describes the level of short-circuit current it can safely interrupt under specified voltage and standard conditions. Neither figure should be substituted for the other.
