Family Overview
Selection And Application Context
Optimizing circuit breaker performance often requires more than just the breaker itself. Our MCB accessories offer crucial functionalities that expand the utility of your electrical installations. Shunt releases (SH5-) enable remote tripping of MCBs, providing an essential safety and control mechanism for emergency shutdowns or automated systems. Auxiliary contacts (AU5-) and alarm contacts (AL5-) provide remote indication of the MCB's status, allowing for integration into building management systems or control panels.
For enhanced circuit protection, our under voltage protectors (UV5-), over voltage protectors (OV5-), and combined under/over voltage protectors (UV5+OV5-) safeguard connected equipment from harmful voltage fluctuations. These devices automatically trip the MCB when voltage levels deviate from safe operating parameters, preventing damage and ensuring system integrity. Designed for panel builders, switchboard assemblers, and electrical accessories distributors, these components are vital for robust circuit protection programs. We also offer ODM and private label manufacturing support to meet specific project requirements.
