Question: I'm looking for a contactor/relay panel that has as many poles as possible, and I'm having a hard time finding anything.The application is an MRI operating room in which many different circuits need to be switched off at once with the push of one button when an MRI scan is being performed. I probably need 50 to 60 relay positions total.The only thing close I've found are lighting control panels. Some of these have as much as 48 relays in them. However, these have many features that I do not need, and I have a feeling this will be more expensive than it needs to be. I really just need a panel that will open and close a bunch of relays at one time.Any ideas? Suggestions?

Custom Panel Fabrication If you cannot find a suitable off-the-shelf panel, you may consider having one custom fabricated to meet your specific requirements. Many electrical contractors offer this service.
Tips for Sourcing Contact manufacturers or distributors of electrical control equipment. Specify the number of poles and voltage required. Inquire about any additional features or functions needed (e.g., protection, monitoring). Obtain quotes and compare pricing from multiple suppliers.
Other Considerations Ensure that the panel has adequate cooling to prevent overheating. Consider the physical space available for the panel. Mount the panel in a location where it is easily accessible for maintenance and troubleshooting. Flag for review
