Relay Test Blocks are used to test relays and metering panels without disrupting the circuit. Relay Test Blocks are designed to be robust and can perform well in different climatic conditions.
Here are some features of Relay Test Blocks:

• Housing: Made of high-grade phenolic molding, which is durable and can withstand different climates
• Terminals: Brass terminals that are nickel plated
• Contacts: Spring-loaded, silver-plated contacts that are separated by insulated barriers
• Protective cover: Fitted to the Relay Test Blocks when not in use, and can be removed for testing
• Contact finger: Fitted to the cover to close the trip contact when inserted
• Test plug: Inserted into the block for testing, and supplied separately
  When testing relay terminal blocks, it’s important to document the results, such as resistance values and continuity readings. This documentation can be useful for troubleshooting and identifying patterns in performance Relay Test Blocks.
