Details

The DEHNguard® SU/MU … surge arresters are modular DIN rail mounted SPDs in the functional Red/line family design and set new standards in terms of safety and user-friendliness. The SPDs are UL 1449 3rd Edition certified as Type 2 Component Assemblies and are designed for all common electrical power systems. These Devices have optimised Voltage Protection Ratings and therefore provide ideal surge protection for the United States and Canadian electrical panel markets.

The enhanced maximum discharge capacity of 50kA, the high short circuit current rating (SCCR) of 200kA and the fact that there is no need for additional overcurrent protection devices make the DEHNguard® SU/MU product family fulfil all requirements of nowadays electrical applications. Besides the variety of features shows that both reliable surge protection and equipment safety are key elements of the modular DEHNguard surge arresters. The application-based product designation, which makes it considerably easier to choose the correct device for the relevant application, as well as the module locking system firmly fixes the protection modules to the base part. Neither vibration during transport nor the enormous electromagnetic forces of discharge can loosen the protection modules. Nevertheless, they can be easily replaced without tools by simply pressing the user-friendly module release button of the protection modules. Each protective circuit of the multipole surge arresters and each protection module are mechanically coded to ensure against installing an incorrect module.

The dual "Thermo Dynamic Control" monitoring device was not only developed on the basis of national and international product standards, but also stands for experience of decades in the world market of surge protective devices and considers practical applications where arresters might be damaged. As with all DEHN surge arresters with "Thermo Dynamic Control", the intensity of the discharge current and the surface temperature of the heavy-duty varistor are evaluated. The visual status indicator with green and red indicator flags shows the availability of every protective circuit. Apart from this standard visual indication, DEHNguard M® SU/MU ... FM devices feature a Form C contact (SPDT).

With its floating changeover contact, the remote signal can be used as a make or break contract according to the particular circuit concept. The surge arresters of the multipole modular DEHNguard® MU family feature multifunctional terminals on a standardised spacing of 1 module for the connection of wires and busbars, allowing easy wiring with other DIN rail mounted devices. Thus, a wide range of applications can be easily connected in series for optimal protection.
