DC Circuit Breaker Alpha+ 500VDC 2P, 20A, C-curve 6kA - EPB63MDC2C20

DC Circuit Breaker Alpha+ 500VDC 2P, 20A, C-curve 6kA - EPB63MDC2C20

The Maxge Alpha+ 500 VDC 2P, 20 A DC circuit breaker is a circuit breaker designed to protect direct current (DC) installations.

With a rated voltage of 500VDC, a rated current of 20A and a two-pole (2P) configuration, this circuit breaker offers effective and safe protection against overloads and short-circuits in medium-power electrical systems.
In addition, it combines thermal overload protection and magnetic overload protection for quick response to sudden power failures.

This circuit breaker has a breaking capacity of 6kA, which allows it to interrupt short-circuit currents of up to 6,000 amperes without compromising the integrity of the device or the safety of the installation. It is therefore a reliable solution for both new installations and extensions to existing switchboards.

As part of Maxge's Alpha+ DC series, it is designed to meet the challenges presented by direct current, especially in modern environments for the generation, storage and use of renewable energy or power electronics.

Main features of the Alpha+ DC MCB 500VDC 2P, 20A

Full bipolar protection

Being a 2-pole MCB (2P), The DC circuit can be disconnected at the same time from the two main conductors (positive and negative), increasing operational safety and facilitating maintenance.

This is particularly important in DC installations, as it ensures complete isolation of the system in the event of a fault and reduces electrical hazards.

More demanding loads

With a 20 ampere rated current, This circuit breaker is designed for circuits that support loads higher than the usual 16 A, guaranteeing precise and reliable protection.

It is most commonly seen protecting intermediate power circuits, non-excessive loads and auxiliary power supplies in complex systems.

Provided that the cables are correctly dimensioned, this circuit breaker guarantees safe, stable and continuous operation of the circuit.

Balance between protection and stability

The DC Alpha+ 500VDC 2P, 20A DC circuit breaker incorporates a firing curve C, which is designed to tolerate moderate current peaks without causing untimely tripping.

The C-curve provides an optimum balance between sensitivity and tolerance, maintaining effective protection against dangerous overcurrents and overloads without affecting the normal operation of the installation.

This avoids nuisance tripping, but does not reduce the protection against real short circuits.
In addition, the installation is more stable.

It is therefore suitable for circuits with moderate starting peaks, such as photovoltaic systems, battery banks, electronic equipment, power supplies, and small DC motors.

High short-circuit resistance

Your 6 kA breaking capacity means that it can safely interrupt major short circuits of up to 6,000 amperes without damage or loss of properties.

It is a value that ensures an adequate and safe level of protection within most industrial or commercial direct current (DC) applications.

It provides a good level of safety and protection for most common low voltage DC installations.

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.

Easy installation and compact design

The DC Alpha+ 2P, 20A is designed to DIN rail mounting, This facilitates a quick and tidy installation in any electrical panel, and favours the expansion and organisation of the distribution.

Your terminals are prepared to accept cables with a cross-section suitable for this current rating (16mm² in flexible cable and 25mm² in rigid cable). This guarantees firm and secure connections, without overheating or false contacts.

In addition, it has a compact 36 mm wide design (18 mm per pole), and it features window for circuit marker y a visual status signalling (on/off), The circuit it protects can be easily identified.
Therefore, it provides a quick diagnosis and is very easy to maintain.

Maxge Alpha+ 2P, 20A, C-curve, 6kA - EPB63ME2C20 - Operation and Applications

This circuit breaker protects the circuit in two ways:

• Thermal protection (overload): cuts off the current if there is a sustained overload, preventing both overheating of the cables and possible damage to the installation.
• Magnetic protection (short circuit): acts almost instantly when there is a strong short-circuit. When this happens, this circuit breaker cuts off the power supply and protects both the installation and the connected equipment.

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 Alpha+ DC Circuit Breaker 500VDC 2P, 20A

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 greater safety and control in installations operating at high DC voltages.
• 2-pole for complete disconnection of the DC circuit: improves safety in maintenance and operation.
• Balanced C-curve: tolerates temporary power surges, without unnecessary tripping.
• High breaking capacity of 6 kA: allows circuits to be effectively protected against significant power failures.
• Versatile installation: is easily mounted on DIN rail, allowing modularity and order in the electrical panel.
• Double thermal and magnetic protection: integrates safe protection against overloads and short circuits.
• Reduces contact wear and prolongs service life: thanks to technical solutions for arc control and adapted geometries.
