How to determine the BOM of ATSNSX references in Singapore Pricebook

How can we help you today?

First we need to understand what the order code mean, in the Singapore Pricebook we have 3 variants

1) Source changeover composed of Switch Disconnectors

2) Source changeover composed of Breakers with identical TM-D trip unit

3) Source changeover composed of Breakers with identical Micrologic 2.3 trip unit

Source changeover composed of Switch Disconnectors

Example reference is ATSNSX010A3F, we can check on its nomenclature as per below:

Source changeover composed of Breakers with identical TM-D trip unit

Example reference is ATSNSX010B3FTM, we can check on its nomenclature as per below:

TM-D

Source changeover composed of Breakers with identical Micrologic 2.3 trip unit

Example reference is ATSNSX040F3FMI2, we can check on its nomenclature as per below:

Mic 2.3

Just to take note that for remote controlled source changeover:

For ComPact NSX100 to NSX630, each circuit breaker (Normal and Replacement) must be equipped with:

- a motor mechanism
- an OF contact
- an SDE contact.

The components are supplied ready for assembly and the circuit breakers prewired. The prewiring must not be
modified.

We can then refer to photo below for typical composition of ATSNSX for 100 to 630A.
