Description
About the Product
The Lauritz Knudsen CM99805OOOO is a Multi-Voltage Shunt Release accessory specifically designed for compatibility with DU400N, DN2, DN3B, DN3, & DN4 series Moulded Case Circuit Breakers (MCCBs). This advanced accessory enables remote tripping of the MCCB through an external electrical control signal, providing enhanced operational control, improved safety, & seamless integration with automation & protection systems. It is particularly suited for high-capacity power distribution networks where remote circuit isolation & fast response capabilities are critical.
The shunt release supports a wide operating voltage range of 110V AC, 240V AC, 415V AC, & 220V DC, making it highly versatile for a broad variety of industrial, commercial, infrastructure, & utility applications. This multi-voltage capability allows a single accessory to be used across different control systems, reducing inventory requirements & simplifying project design, maintenance, & spare parts management.
When an external control signal is applied, the shunt release instantly energizes & actuates the MCCB tripping mechanism, disconnecting the electrical circuit & ensuring rapid isolation of connected loads. This functionality is essential for emergency shutdown systems, fire protection systems, safety interlocking circuits, remote-control applications, & automated process control systems where immediate disconnection of power may be required.
The accessory enables seamless integration with PLCs, Building Management Systems (BMS), SCADA platforms, fire alarm systems, & centralized automation networks. This capability enhances system responsiveness & allows critical power distribution equipment to be controlled remotely & safely.
Designed specifically for heavy-duty MCCBs used in high-current applications, the shunt release delivers dependable performance even in demanding operating environments. It functions independently of the MCCB's internal protection system & does not interfere with overload, short-circuit, or fault protection characteristics.
Its compact & durable construction ensures simple installation, reliable operation, & a long service life while supporting both new projects & retrofit upgrades.
This multi-voltage shunt release is the ideal solution for applications requiring remote tripping, wide control voltage compatibility, automation integration, & enhanced electrical safety management.
