The Maxge Alpha+ 500 VDC 2P, 63A DC MCB is a protective circuit breaker specifically designed for high current direct current (DC) circuits.<\/p>\n
With a rated voltage of 500VDC, a rated current of 63A and a two-pole (2P) configuration, this circuit breaker offers comprehensive and reliable protection against prolonged overloads and sudden short-circuits, providing safety, robustness and performance in modern electrical systems operating on continuous power.<\/p>\n
Thanks to its 6kA breaking capacity, the circuit breaker is able to safely interrupt short-circuit currents of up to 6,000 amperes, protecting both the installation and the connected equipment.
\nIt is therefore an ideal choice for applications where high conductivity and reliable protection against electrical faults is required.<\/p>\n
This MCB belongs to Maxge's Alpha+ DC family, a range of products designed to meet the specific needs of direct current, where the absence of zero crossings and the management of electric arcs require specialised technologies and designs.<\/p>\n
Being a 2-pole MCB (2P)<\/strong>, The DC circuit can be disconnected at the same time from the two main conductors (positive and negative), increasing operational safety and facilitating maintenance.<\/p>\n 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.<\/p>\n With a rated current 63 amps<\/strong>, This circuit breaker is designed to protect circuits with high power loads, feeding large photovoltaic strings, inverter auxiliary sub-circuits, industrial equipment and demanding loads.<\/p>\n Provided that the cables are correctly dimensioned, this circuit breaker guarantees safe, stable and continuous operation of the circuit.<\/p>\n The Alpha+ 500VDC 2P, 63A DC circuit breaker incorporates a firing curve C, <\/strong>which is designed to tolerate moderate current peaks without causing untimely tripping.<\/p>\n 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.<\/p>\n This avoids nuisance tripping, but does not reduce the protection against real short circuits. It is therefore suitable for circuits with moderate starting peaks, such as photovoltaic systems, battery banks, electronic equipment, power supplies, and small DC motors.<\/p>\n Your 6 kA breaking capacity<\/strong> 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.<\/p>\n This cutting power provides an adequate level of safety and reliability in most demanding applications.<\/p>\n In other words, this circuit breaker provides a reliable level of protection for everyday use.<\/p>\n In direct current, circuit interruption is more demanding than in alternating current due to the absence of natural zero crossing.<\/p>\n For this reason, this circuit-breaker is designed with internal arc extinguishing systems<\/strong> adapted to DC, guaranteeing a safe and durable cut.<\/p>\n Consequently, this circuit breaker offers a robust and reliable solution for protecting DC electrical installations with currents up to 40A.<\/p>\n The Alpha+ 500VDC 2P, 63A DC circuit breaker is designed for DIN rail mounting<\/strong>, It is quick and easy to install in any standard electrical panel.<\/p>\n Your compact 36 mm wide design<\/strong> (18 mm per pole), helps to optimise the space available in the frame and features window for circuit marker<\/strong> y a visual status signalling (on\/off)<\/strong>, The circuit it protects can be easily identified.<\/p>\n In addition, it has some terminals<\/strong> that are prepared for cables suitable for this current (25<\/strong> mm\u00b2 in flexible cable and 35mm\u00b2 in rigid cable<\/strong>). This circuit breaker protects the circuit by means of two complementary systems:<\/p>\n In this way, the circuit breaker protects against both progressive increases in current and sudden faults, ensuring a fast and effective response.<\/p>\n This circuit breaker has the following advantages:<\/p>\nDemanding high power loads<\/h3>\n
Balance between protection and stability<\/h3>\n
\nIn addition, the installation is more stable.<\/p>\nHigh resistance<\/h3>\n
Safety in direct current (DC) installations<\/h3>\n
Quick installation and practical design<\/h3>\n
\nThis ensures firm, secure and durable connections.<\/p>\nAlpha+ 500VDC 2P, 63A, C-curve, 6kA - EPB63MDC2C63 DC Circuit Breaker - Operation and Applications<\/h2>\n
