The GA&DA GDDC5-63 DC 4 Pole 1000V Miniature Circuit Breaker (MCB) is a specialized protection device engineered for high-voltage DC systems such as solar PV installations, battery storage systems, and industrial DC power networks. Designed with a 4-pole configuration, it provides enhanced safety and reliable disconnection in demanding applications.
With a rated voltage of up to 1000V DC and current options typically up to 63A, this MCB offers strong protection against overloads and short circuits. It is built to quickly interrupt fault currents, helping prevent damage to expensive equipment and ensuring system stability.
The breaker uses a thermal-magnetic trip mechanism, combining overload protection with instantaneous short-circuit response. Its high breaking capacity (commonly around 6kA) ensures safe interruption of fault conditions, which is critical in DC systems where arc suppression is more challenging than AC circuits.
Designed for DIN rail mounting, the GA&DA GDDC5-63 allows easy installation in distribution boards, combiner boxes, and control panels. Its compact and durable construction ensures long service life even in harsh environments, including outdoor solar setups.
This DC MCB is widely used in photovoltaic systems, DC distribution panels, EV charging setups, and industrial control systems, where dependable and safe DC protection is essential.
