I am seeking solutions to incorporate MOVs and fuses for solenoid PLC outputs within a compact panel. Are there terminal blocks available that come equipped with both MOVs and fuses? While I am familiar with fuse and suppressor terminal blocks individually, I have yet to come across a single unit that combines both components. Is there a specific reason for this absence in the market? I may be overlooking a key aspect. Any advice or information on this topic would be highly valued. Thank you for your consideration.
Unsure if this fits your needs? Explore the benefits of Allen-Bradley's Bulletin 1492 Fuse & Surge Suppressor Finger-Safe Terminal Blocks. These two-circuit blocks feature a unique design with a series resistor/capacitor connected in parallel to a metal oxide varistor (MOV). Learn more at www.rockwellautomation.com.
After searching the 1492 catalog, I was unable to locate a part number that includes both a fuse and a MOV terminal block.
Is it possible to connect individual Metal Oxide Varistors (MOVs) directly to screw terminals?
Indeed, the task is feasible but the available panel space is restricted. I intended to utilize the AB 1492-FB1J30 and Phoenix TTC-6-MOV-C-120AC-UT-I components, yet they prove to be too bulky for the allotted space. It is surprising that a more compact alternative is not available in the market.
Where can I find a glass fuse holder (5-7mm wide) in Phoenix?
You've brought up an interesting point. To my knowledge, terminal blocks combining both MOVs and fuses into a single unit aren't commonly available. This could largely be due to technical issues, as the integration of both components into a compact block might affect its heat dissipation efficiency. Also, separating them allows system engineers to be more flexible when designing circuits, so it could ultimately be a matter of practicality. Nevertheless, you could try customizing your own solution by assembling both MOV and fuse into a single DIN rail mounted case. Always ensure, however, that your solution complies with the required safety standards.

Answer: 1. Are there terminal blocks available that come equipped with both MOVs and fuses? - Currently, there isn't a single unit that combines both MOVs and fuses in terminal blocks. They are typically available as separate components. 2. Why aren't there terminal blocks with both MOVs and fuses in the market? - The absence of terminal blocks with both MOVs and fuses could be due to design limitations, cost considerations, or the specific requirements of the target market.
Answer: - Yes, you can incorporate MOVs and fuses separately in your panel to protect solenoid PLC outputs. This will involve using separate terminal blocks for each component.
