Frequently asked questions
How do I get current pricing and availability for S403M-C4?
Submit an RFQ. The part is sourced to order through independent distribution; pricing and stock status are confirmed at quote time.
What is the S403M-C4's listed weight?
The listed weight is 0.59 kgs.
Will S403M-C4 drop into a panel specified around S273-K40A?
Both are DIN rail mount miniature circuit breakers in the same top category, so the mounting footprint is compatible. However, verify the electrical ratings (current, breaking capacity, trip curve) against your panel design before swapping — the S273-K40A is a different model with a different weight (0.45 kgs) and likely different electrical characteristics.
