Engineered for ultimate thermal-magnetic protection in commercial, industrial, and residential electrical panels across Turkey.
Navigating grid modernization, industrial expansion in Marmara, and rigorous Turkish Standards Institution (TSE) compliance.
Turkey stands as a critical industrial nexus bridging Europe and Asia. With rapid manufacturing modernization in provinces such as Kocaeli, Bursa, Istanbul, and Izmir, alongside massive investments in distributed solar PV generation across Central Anatolia, the demand for resilient, high-performance low-voltage protection hardware has reached an unprecedented peak. Power stability is no longer just a technical requirement—it is a vital pillar of industrial productivity, fire safety, and operational continuity.
As a global pioneer in distribution switchgear and control equipment, Wenzhou OFA Electrical Technology Co., Ltd. engineered the OFKL Series Miniature Circuit Breaker (MCB) platform to specifically address the rigorous stress conditions present in modern Turkish power grids. Designed to handle intense harmonic distortion, ambient temperature fluctuations ranging from Anatolian winters to Aegean summer heats, and rapid load cycling, the OFKL series delivers unrivaled trip accuracy, high short-circuit breaking capabilities (6kA to 10kA), and long mechanical endurance.
The Turkish electrical market is governed by stringent technical harmonization under European Union directives (Low Voltage Directive 2014/35/EU and Electromagnetic Compatibility 2014/30/EU) alongside domestic certification from TSE (Türk Standardları Enstitüsü). Contractors, panel builders (Pano Üreticileri), and EPC firms operating in Turkey require suppliers who can seamlessly combine international standard compliance with flexible OEM/ODM manufacturing capability.
Inside the OFKL Series: Thermal-magnetic tripping accuracy, arc quenching technology, and flame-retardant materials.
Features an advanced 12-plate arc chute chamber that rapidly cools and extinguishes electric arcs during short-circuit faults within milliseconds, protecting critical downstream equipment from thermal damage.
Integrates a bimetallic strip for inverse time-delay overload protection combined with a instantaneous electromagnetic coil mechanism for instant high-current fault interruption (Curves B, C, and D available).
Utilizes high-content silver-graphite contact tips engineered for minimal electrical resistance, reduced temperature rise, and exceptional resistance to contact welding during high-energy short-circuit events.
