MCB
Being a key element of our last distribution range our MCBs provide accurate overload and short circuit protection for households and businesses. With its high breaking power and in compliance with the IEC standards, the device guarantees isolation. We operate in the field of OEM/ODM customization and provide the possibility of choosing the required current rating of poles.
RCCB
We provide RCCBs for earth leakage protection against ground faults, thus avoiding risks of electric shock and fire in homes, businesses and public places. Built to have the highest sensitivity and effective tripping mechanism, these products follow international safety standards and help ensure human safety. We also offer OEM/ODM customization with sensitivity ratings and pole numbers based on the requirements of any project across the globe.
RCBO
RCBOs provide protection from overloads, short circuits, and earth leakage in a single compact unit. They are designed to provide instant fault detection with high breaking capacity according to the latest IEC specifications. We offer full OEM/ODM customization, which allows our RCBOs to match various project specifications.
ACB
Our ACBs are high-current protection devices designed for main distribution switchboards, delivering reliable overload, short-circuit, and ground fault protection in industrial and commercial power networks. Featuring intelligent electronic trip units with adjustable protection parameters and communication capabilities, these devices ensure system selectivity and coordination. We offer OEM/ODM customization with various frame sizes, current ratings (up to 6300A), and communication protocols.
ATS
Our ATS solutions automatically transfer loads between primary and standby power sources upon mains failure, ensuring uninterrupted power supply for critical applications in power distribution networks. Engineered with intelligent controllers and mechanical interlocking, these devices enable seamless switching with adjustable time delays and voltage monitoring. We offer OEM/ODM customization with various current ratings, pole configurations, and control logic to match diverse backup power requirements.
MCCB
Our MCCBs provide reliable overload and short-circuit protection for branch circuits in power distribution networks, bridging the gap between main ACBs and final MCBs. Featuring high breaking capacities, thermal-magnetic or electronic trip units, and compact footprints, these devices deliver selective coordination and robust performance in industrial and commercial applications. We offer OEM/ODM customization with various frame sizes, breaking capacities, and trip unit configurations.
