DC Circuit Breaker Alpha+ 500VDC 2P, 16A, C-curve 6kA - EPB63MDC2C16

DC Circuit Breaker Alpha+ 500VDC 2P, 16A, C-curve 6kA - EPB63MDC2C16

The Maxge Alpha+ 500VDC 2P, 16A DC Circuit Breaker is a circuit breaker designed specifically for the protection of direct current (DC) circuits, offering safety, robustness and reliability in modern DC applications such as photovoltaic installations, battery systems, renewable energy and other industrial DC applications.

With a rated voltage of 500VDC, a current of 16 amps and a 2-pole (2P) configuration, this device ensures effective protection against overloads and short-circuits in the most demanding electrical systems.

In addition, it has a breaking capacity of 6kA, which allows it to interrupt high fault currents safely, protecting both the installation and the connected equipment.

This circuit breaker is part of the Alpha+ DC family, developed taking into account the technical requirements of direct current, where the absence of zero crossing of the electrical signal and the possible persistence of arcs require a specific design to interrupt fault currents more effectively than traditional circuit breakers intended for alternating current.

Main features of the Alpha+ DC Circuit Breaker 500VDC 2P, 16A

Complete phase and neutral protection

Being from 2-pole (2P), This circuit breaker protects and disconnects the phase and neutral at the same time. This ensures that the circuit is completely isolated when the circuit breaker is manually tripped or switched off, increasing safety during maintenance or servicing work on the electrical panel.

This type of protection is particularly recommended in direct current installations where it is necessary to cut off both poles to ensure complete isolation of the circuit.

Therefore, this model is ideal for applications where a higher level of safety in circuit switching is required.

Typical use in domestic installations

With a rated current 16 amps, This circuit breaker is perfect for circuits with moderate consumption and is suitable for intermediate loads or sub-circuits in more complex systems.

Provided that the installation is properly carried out, the circuit breaker guarantees stable, safe operation without unnecessary outages.

Stability without nuisance tripping

The firing curve C allows the circuit breaker to withstand moderate current peaks, such as those that occur when switching on certain electrical appliances, without causing unnecessary tripping.

This means fewer unplanned outages, greater convenience of use, and good protection against real overloads and short circuits.

Therefore, the C-curve is one of the most commonly used curves in general installations.

High resistance

Your 6 kA breaking capacity means that this circuit breaker is capable of safely interrupting short-circuit currents of up to 6,000 amperes without damage or loss of protective properties.

This breaking capacity provides an adequate level of safety and reliability in most low/medium power DC applications.

In other words, this circuit breaker provides a reliable level of protection for everyday use.

Safety in direct current (DC) installations

The interruption of direct current is more demanding than alternating current due to the absence of zero crossing.

For this reason, this circuit breaker is designed with arc extinguishing systems suitable for DC, guaranteeing a safe and durable cut.

As a result, the Alpha+ DC MCB offers a robust, reliable and ready-to-use solution for effective protection of DC electrical systems.

Quick installation and practical design

The Alpha+ 500VDC 2P, 16A DC Circuit Breaker is designed for DIN rail mounting, It is quick and easy to install in any standard electrical panel.

Your compact 36 mm wide design (18 mm per pole), helps to optimise the space available in the frame and features window for circuit marker y a visual status signalling (on/off), The circuit it protects can be easily identified.

In addition, it has some terminals that are prepared for cables suitable for this current (16mm² in flexible cable and 25mm² in rigid cable).
This ensures firm, secure and durable connections.

Alpha+ 500VDC 2P, 16A, C-curve, 6kA - EPB63MDC2C16 DC Circuit Breaker - Operation and Applications

This circuit breaker protects the circuit by means of two complementary systems:

• Thermal protection (overload): acts when the current exceeds safe values for a prolonged period of time, preventing excessive heating of the conductors and possible damage to equipment or risk of fire.
• Magnetic protection (short circuit): responds almost instantaneously to very high currents, cutting off the supply and protecting the installation against serious faults.

In this way, the circuit breaker protects against both progressive increases in current and sudden faults, ensuring a fast and effective response.

Main advantages of the DC Alpha+ 500VDC 2P, 16A DC circuit breaker

This circuit breaker has the following advantages:

• Safe DC operation: guarantees a correct extinguishing of persistent electric arcs in direct current.
• Optimised for direct current up to 500 V: provides safety in installations with high voltages.
• 2-pole for complete disconnection of the DC circuit: improves safety in maintenance and operation.
• Balanced C-curve: withstands common start-up peaks, without nuisance tripping.
• High cutting capacity: its value of 6 kA makes it possible to protect circuits with high safety requirements.
• Quick and modular installation: is easily mounted on DIN-rail, allowing tidy extensions.
• Integrated overload and short-circuit protectionCombination of thermal and magnetic protection.
• Reduces contact wear and prolongs service life: thanks to technical solutions for arc control and adapted geometries.
