VSSC4 MOV 24VAC/DC
VSSC4 MOV 24VAC/DC:
- Overvoltage coupling along the conductor path might impair or destroy sensitive signal inputs.
- It is critical to offer security in the immediate proximity of I&C equipment.
- Weidmüller's extensive product line for the I&C industry includes 2-piece, pluggable designs as well as modular terminals for tension clamp or screw connections.
- These items are compatible with both binary and analogue signals.
- Weidmüller also provides additional designs with integrated components like gas discharge tubes and varistors.
- Variator is an abbreviation for Weidmüller's flexible and variable surge protection, which is tested in compliance with product standard IEC61643-21.
- The VARITECTOR series is suitable for applications in IEC 61643-22 / VDE 0845-3 classes C1, C2, C3, and D1.
- The VARITECTOR SPC, SSC, and MCZ OVP product families effectively integrate electrical and mechanical qualities.
- Size and ease of handling are crucial considerations.
- In industrial and process automation applications as well as building automation, this surge prevention is appropriate for cramped areas.
