This listing includes a combined protection set from ABB consisting of:

• ABB DDA204 — a 4-pole Type A residual current protection module (RCCB add-on)
• ABB S204 C25 — a 4-pole miniature circuit breaker (MCB) rated at 25 A, curve C

Together they form a high-performance RCBO-equivalent protection assembly, delivering both overcurrent and residual current protection in one integrated solution. This combination is widely used in industrial installations, commercial electrical panels, and photovoltaic systems requiring reliable 4-pole safety protection.

Engineered according to ABB’s stringent quality standards, the DDA204 + S204 C25 pairing ensures precise tripping, high endurance, and stable operation even in demanding electrical environments.
