Product details

30A K-Trip MCB for DIN Rail Panels

The S801U-K30 is a 30-amp, single-pole miniature circuit breaker rated for 240 VAC with a K-trip curve, designed for DIN rail mounting in control panels and distribution boards. The K-trip characteristic provides a higher magnetic trip threshold than a standard B or C curve — typically 8–12× rated current — making it suited for loads with moderate inrush, such as motor control circuits or transformer primaries, where nuisance tripping on startup needs to be avoided while still providing short-circuit protection.

Frequently asked questions

Where can I buy S801U-K30 and how do I get a price?

The S801U-K30 is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the S801U-K30 part number and its listed weight?

The part number is S801U-K30. Its listed weight is 0.45 kg.

Will S801U-K30 drop into a panel specified around 1SDA050917R1 without rewiring?

Both parts share the same 0.45 kg weight and Molded Case Circuit Breaker subcategory, suggesting a similar physical footprint. However, verify the trip curve, current rating, and terminal layout of 1SDA050917R1 against the S801U-K30 before assuming drop-in compatibility — the overcurrent protection characteristic may differ.
