The 48449 closing coil is a control device specifically designed for use in industrial power circuit breakers of the MasterPact NT/NW series, enabling immediate remote tripping. It allows remote control of the circuit breaker in conjunction with a tripping coil MX and a motor drive MCH, thereby achieving a fully automated control of the switching process. The operation is performed via Modbus communication, ensuring secure and reliable remote control within industrial networks. The coil is designed for plug-in technology and supports operating voltages of 24/30 V DC and 24 V AC, making it suitable for a wide range of applications in industrial automation. As part of a modular switching system, it offers high flexibility and deep integration into existing control architectures.
