WPO 4 with fitted varistor
Weidmüller varistor terminals have been designed for retrofitting
electronic components, e. g. varistors, diodes, gas discharge
tubes, etc. These ”electronic terminals” no longer have to be
configured prior installation to subsequently be delivered with
soldered components which can no longer be distinguished.
The significant advantages of this new design are:
• Cost saving:
• Components can be changed quickly on site
• Service is limited to visual inspection
• Clarity
• Components are easy to distinguish
• Flexibility:
• Components can immediately be adapted to changed
conditions
• Note:
Never change electric components in energised systems
