Frequently asked questions
How do I get current pricing and availability for S273-K16A?
Submit an RFQ through the storefront. Availability and current pricing are confirmed at quote time through independent distribution channels.
What is S273-K16A's listed part number?
The listed part number is S273-K16A.
What is S273-K16A's listed weight?
The listed weight is 0.53 kg.
Will S273-K16A drop into a panel designed for S273-K40A without rewiring?
Yes. Both share the same S273-series DIN-rail footprint and clip arrangement. The 16 A rating is lower than the 40 A, so branch-circuit wire sizing and upstream protection must already be rated for the lower current — the panel mechanical fit is identical.
