Details
The modular DEHNguard modular YPV SCI ... FM surge arresters are specifically designed for protecting equipment in photovoltaic systems. The devices are available for 1200 V and 1500 V and cover the most common voltage levels.
The following application features characterise the modular arrester design of this Red/Line product series. The module locking system firmly fixes the protection modules to the base part. Neither shock nor vibration nor the enormous forces of discharge affect the safe connection to the protection module. Nevertheless, the protection modules can be easily replaced without tools by simply pressing the easy-to-use module release button of the protection modules. Every protective path of DEHNguard modular YPV SCI ... FM and every protection module is mechanically coded to ensure against installing the incorrect module.
The fault-resistant Y circuit with three high-capacity varistors prevents damage to surge protective devices in case of insulations faults in the generator circuit of the photovoltaic generator.
The green and red indicator flags show the availability of every protective circuit. Apart from this visual indication, DEHNguard YPV ... FM arresters also feature a three-pole remote signalling terminal. With its floating changeover contact, the remote signal can be used as make or break contact according to the particular circuit concept. As with all surge arresters of the modular DEHNguard modular family, DEHNguard modular YPV ... FM arresters incorporate multifunctional terminals on a standardised spacing of 1 module for connecting conductors and busbars, allowing easy wiring with other DIN rail mounted devices.
