In general, the price of an Assembly will increase with increased levels of separation and/or types of construction.
Choosing the arrangement with the most internal barriers will not always lead to the most appropriate solution. Where specific requirements are not stated or identified, the manufacturer is likely to assume the most cost effective solution will satisfy the customer’s needs and offer it accordingly.
So here is the description of Form 1, the cheapest level of separation:
Form 1 covers overall Assemblies which are enclosed so as to provide protection against contact with any internal live parts or components, but where no internal separation is provided for functional units or terminations.
For Form 1:
- Busbars are not separated from the functional units,
- Functional units are not separated from other functional units.
- Functional units are not separated from any incoming or outgoing termination.
- Busbars are not separated from any incoming or outgoing terminations.
