Engineered for high breaking capacity and versatile adjustable protection settings, tailored for the demanding power distribution requirements in Barcelona's commercial grids and industrial plants.
As Catalonia establishes itself as a leading smart energy hub in the Mediterranean, the demand for highly reliable Molded Case Circuit Breakers (MCCB) has reached unprecedented levels. Barcelona's industrial sector—ranging from the Zona Franca logistics park to chemical complexes in Tarragona—demands electrical protection switchgear that conforms to strict UNE-EN 60947-2 standards. System integrators, panel builders, and electrical distributors across Spain require solutions that can survive challenging environments, including coastal humidity and high ambient thermal conditions.
Thermal-magnetic MCCBs represent the critical frontline defense in low-voltage electrical installations. Utilizing a bimetallic strip for inverse-time overload protection and an electromagnetic mechanism for instantaneous short-circuit protection, these devices provide reliable defense for motors, distribution boards, and industrial generators. For global procurement teams, sourcing MCCBs that combine cost efficiency with European certifiability is the ultimate objective.
Acereare Electric, established in 2015 with its specialized manufacturing subsidiaries RuiRui Electric and KeRui Electric, bridges the gap between high-precision Chinese manufacturing scaling and European specification compliance. Our engineering roadmap focuses on optimizing contact systems to handle breaking capacities up to 200kA at 400VAC/690VAC. By integrating specialized silver alloy contacts and optimized arc chutes, our thermal-magnetic breakers guarantee minimal arc duration under short-circuit conditions, increasing the longevity of the electrical network.
Furthermore, our adjustable thermal-magnetic range allows field engineers in Barcelona's installations to fine-tune protection parameters on-site. Adjustable thermal ranges (typically 0.8 to 1.0 times the rated current) allow adaptation to local ambient load profiles without requiring complete component replacements.
Operating across two dedicated manufacturing plants, Acereare integrates raw material processing, copper stamping, plastic molding, and assembly in-house. This comprehensive manufacturing control minimizes supply chain risks, allowing us to guarantee consistent lead times for large-scale infrastructure projects in Barcelona.
By implementing enterprise management tools including PLM, BI, ERP, and MES, every circuit breaker is fully traceable. From raw copper and steel component stamping to final thermal calibration, each unit is checked against target trip curves. This ensures that the protection devices installed in Catalan factories deliver reliable performance when it matters most.
