Schneider 20A 1P MCB Circuit Breaker A9K24120 is an option among MCB automatic circuit breakers at Bashiti Stores, designed to protect circuits from overloads and short circuits. In this version, the rated current is 20 Amperes and the number of poles is 1P. These specifications distinguish this model from other alternatives in the same series; match them with your circuit requirements and do not choose a higher amperage breaker just to increase the operating margin.
Practical Benefits
- Combines overload and short-circuit tripping functions in a single modular device.
- Distributing protection across independent circuits helps organize the distribution board and identify the affected circuit when a fault occurs.
- 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, electrical 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 solely on the type of device or the shape of the breaker.
Installation and Verification Procedure — For the Specialized Technician
The following steps outline the general workflow. Refer to the manufacturer's manual for model A9K24120 to determine terminals and tightening values. Do not work on a live circuit.
- The technician disconnects all power sources, secures them against reconnection, 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 conductor cross-sections and protection coordination.
- Mounts the unit on the rail or its designated position after ensuring compatibility, and identifies the supply and load side based on the manufacturer's diagram for this reference.
- Performs the connections according to the tightening torque, stripping length, and wire gauges specified in the model manual; do not transpose these values from a similar device.
- Checks the integrity of the mounting and connections, closes the covers, and performs the required functional and protection tests before handing over the circuit.
Frequently Asked Questions Before Purchase
Does this breaker protect against earth leakage?
The MCB is intended for overload and short-circuit protection and does not replace earth leakage protection. Check for the need for an RCCB or RCBO within the panel design.
Should I replace a breaker that trips constantly with one of a higher amperage?
No. You must first determine the cause of tripping and inspect the load, cable, and connections. Increasing the amperage without analysis may leave the wires without appropriate 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 safely interrupt under specified voltage and standard conditions. One number cannot be substituted for the other.
