Schneider MCB 40A 1P A9K24140 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 Amps and the number of poles is 1P. This data distinguishes the model from other alternatives in the same series; match it with the circuit requirements and do not choose a higher current breaker just to increase the operating margin.
Practical Benefits
- Combines the functions of overload and short-circuit tripping into a single modular device.
- Distributing protection across independent circuits helps organize the distribution board and identify the affected circuit in case of a fault.
- Selecting the correct current, number of poles, and tripping curve provides the basis for aligning the breaker with the circuit requirements.

Who Needs This Product?
Electricians, installation contractors, and homeowners or shop owners who are setting up a new distribution board or replacing a breaker that matches an existing circuit. The choice 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 Procedure — For Professional Electricians
The following steps outline the general workflow. The manufacturer's diagram for reference A9K24140 must be used to identify terminals and tightening values. Do not work on a circuit connected to a power supply.
- The technician disconnects all power sources, secures them against reactivation, and verifies the absence of voltage with a suitable tool.
- Matches the device reference, number of poles, current, and voltage with the panel diagram, and reviews the conductor cross-section and protection coordination.
- Mounts the device on the rail or its designated position after ensuring compatibility, and identifies the supply and output from the manufacturer's diagram for this reference.
- Carries out connections using the tightening torque, stripping length, and wire gauges specified in the model manual; these values should not be transferred from a similar device.
- Checks the tightness of the mounting and connections, closes the covers, and performs the required operational and protection tests before handing over the circuit.
Frequently Asked Questions Before Buying
Does this breaker protect against earth leakage?
An MCB is designed for overload and short-circuit protection and does not replace the need for earth leakage protection. The need for an RCCB or RCBO should be reviewed within the panel design.
Should I replace a breaker that keeps tripping with one of a higher amperage?
No. First, identify the cause of the tripping and inspect the load, cable, and connections. Increasing the amperage without study could leave the wires without proper protection.
What is the difference between Amperage and Breaking Capacity?
Amperage is the rated current of the breaker, while breaking capacity describes the level of short-circuit current it can disconnect within specific voltage and standard conditions. Do not substitute one figure for the other.
