Maxge Alpha+ 4P, 40A, C-curve, 10kA - EPB63H4C40

The Maxge Alpha+ 4P, 40A magneto-thermal circuit breaker is a magneto-thermal circuit breaker designed to comprehensively protect three-phase electrical installations with neutral against the main current anomalies, such as overloads and short-circuits.

It is a robust and versatile device, combining thermal and magnetic trip protection to ensure effective, safe and reliable protection in advanced residential environments as well as in commercial or industrial installations.

Main features of the Maxge Alpha+ 4P, 40A circuit breaker

Comprehensive protection

This circuit breaker is made of 4-pole (4P), This means that it simultaneously protects all three phases and the neutral conductor.

This configuration is essential in three-phase electrical panels, as it ensures total isolation of the circuit when it operates, preventing residual voltages from remaining in any of the conductors and improving safety for people and connected equipment.

This configuration is widely used in general power supplies, distribution lines to subpanels, three-phase machinery with neutral, air conditioning, pumps, small motors, and circuits where a uniform cut-off of all poles is required.

Balanced power and load capacity

With a nominal current (In) of 40 amps, This circuit breaker is designed for medium power circuits or main/derivative lines where significant loads are handled. This capacity makes it possible to supply equipment with moderate consumption and several devices at the same time within an installation.

In practical terms, a 40 A circuit breaker allows working with continuous loads within the range foreseen by the circuit design, provided that the cable section and the rest of the protection elements of the switchboard (differential and other protection elements) are adequately dimensioned.

In addition, its operating voltage is up to 415/240 V AC.
This makes it suitable for most standard three-phase installations.

Short-circuit robustness

The 10 kA breaking capacity indicates the ability of the device to safely interrupt a high short-circuit current without damage or compromise to the installation.

With a rating of 10,000 amperes, this device can interrupt severe short-circuit faults occurring relatively close to the transformation point or a supply with a high level of available power.

This provides a high level of safety even in extreme fault situations, making this circuit breaker a recommended option in switchboards where extra resistance and reliability are required.

Sensitivity and tolerance to peak loads

The Maxge Alpha+ 4P, 40A Magnetotermico Maxge Alpha+ 4P, 40A features a firing curve C better tolerates current spikes caused by starting small motors, starters, transformers or power supplies, reducing untimely tripping and maintaining an effective level of protection against dangerous overcurrents

This makes it a very versatile and common choice in varied installations where there is a mix of resistive and moderate peak starting loads.

Installation and design

In terms of installation, it is designed to DIN rail mounting.
This facilitates their integration into standard switchboards and allows for a quick, tidy and professional installation.

Your terminals are prepared to accept conductors of suitable cross-section for this current rating (25 mm² in flexible cable and 35 mm² in rigid cable). This ensures firm and secure connections that reduce the risk of false contacts or overheating.

The design of this circuit-breaker stands out due to its robust construction and its compact dimensions (72 mm wide).

It offers convenient operation by means of window for circuit marker and a visual status signalling (on/off), facilitating the identification of the circuit it protects.
It also provides rapid diagnosis and maintenance.

Maxge Alpha+ 4P, 40A, C-curve, 10kA - EPB63H4C40 - Operation and Applications

This circuit breaker acts as a fundamental protection element in electrical distribution because it combines thermal and magnetic protection in a single mechanism:

• Thermal protection (overload): acts against prolonged overloads, disconnecting the circuit when the current exceeds safe values, thus preventing overheating of the conductors and avoiding damage to cables, equipment or risk of fire.
• Magnetic protection (short circuit): acts very quickly in the event of short circuits, interrupting high fault currents and protecting both the installation and the connected equipment.

It is ideal for use in main or secondary switchboards in industrial, commercial or residential buildings with demanding loads. It thus provides robust and effective protection.

Its 4-pole design covers both three-phase supply and neutral conductor protection, which is crucial for balanced systems or with single-phase loads connected in combination.

Main advantages of Maxge Alpha+ 4P, 40A

The advantages of this circuit breaker are as follows:

• Effective protection: offers a greater margin of protection against overloads and short circuits, reducing the likelihood of serious damage in three-phase networks with neutral.
• High cutting capacity: with 10 kA, suitable for demanding environments.
• Firing curve: type C balanced, ideal for multiple industrial applications.
• Compatibility: can be integrated seamlessly with large cross-section cables, add-on accessories and in standard distribution systems.
• Easy installation and maintenance: the modular format and well-dimensioned terminals facilitate safe and fast connections, allowing easy circuit identification.
• Regulations and certifications: compliance with recognised international standards guarantees quality and reliability for demanding installations.
