DDA200APR

In the realm of electrical distribution and automation, the DDA200APR series represents a specialized category of residual current circuit breakers with overcurrent protection (RCBOs), designed to combine the functions of a miniature circuit breaker (MCB) and a residual current device (RCD) in a single compact unit. These devices are typically rated for currents up to 63A, with a breaking capacity of up to 10kA, and are available in 1P+N, 2P, 3P, and 4P configurations. They operate at standard voltages of 230/400V AC, with a frequency of 50/60Hz, and offer sensitivity levels such as 30mA, 100mA, or 300mA for earth leakage protection. The DDA200APR series is known for its robust construction, featuring a modular design that allows for easy installation on DIN rails within electrical panels. These RCBOs provide both overcurrent and short-circuit protection, as well as protection against indirect contact and fire hazards due to earth faults. They are often equipped with indicator flags for trip status and test buttons for periodic verification. The series is widely recognized under various international standards, including IEC 61009, and is synonymous with terms like 'residual current circuit breaker with overcurrent protection' or 'combined RCD/MCB' in different markets.

The DDA200APR series is primarily deployed in residential, commercial, and industrial electrical installations where space is at a premium and comprehensive protection is required. Common applications include main distribution boards, sub-distribution panels, and final circuits in buildings such as apartments, offices, schools, hospitals, and factories. These devices are essential in environments where there is a high risk of electric shock, such as in wet areas like bathrooms, kitchens, and outdoor installations. They are also used in industrial settings to protect machinery and equipment from earth faults, ensuring operational continuity and safety. The series is particularly suited for retrofitting older installations that require upgraded protection without extensive rewiring, as well as for new constructions that must comply with stringent electrical safety regulations.

Within the DDA200APR category, the primary articles are identified by specific codes that denote their electrical characteristics. For example, the DDA200APR-40/0.03 represents a 40A, 30mA sensitivity unit, while the DDA200APR-63/0.3 indicates a 63A, 300mA model. The code structure typically follows the pattern 'DDA200APR-[Current]/[Sensitivity]', where current is in amperes (e.g., 25, 40, 63) and sensitivity is in amperes (e.g., 0.03 for 30mA, 0.1 for 100mA, 0.3 for 300mA). Additional variants may include suffixes for pole configurations, such as 'DDA200APR-40/0.03-2P' for a 2-pole version. These articles are available in both Type A and Type AC versions, with Type A being suitable for pulsating DC residual currents. The series is complemented by accessories like busbars and sealing covers, but the core articles are the RCBOs themselves.
