Product details

The Siemens SENTRON 5SY4614-7 is a 4-pole (3P+N) miniature circuit breaker with a C tripping characteristic, rated 0.3 A at 35 °C and 400 V AC.

The 0.3 A rating at 35 °C is the continuous current the breaker carries without tripping; derate to 0.29 A at 40 °C, 0.28 A at 45 °C, 0.27 A at 50 °C, 0.26 A at 55 °C, and 0.25 A at 60 °C if the panel ambient runs warm. The 10 kA SCCR per EN 60898 is the standard for final circuits in residential and commercial distribution boards; the 35 kA per IEC 60947-2 applies when the breaker is used in industrial switchgear where higher prospective fault currents are possible.

Panel integration

Halogen-free and silicon-free construction suits environments where outgassing must be minimized — clean rooms, medical, or telecom shelters.

Frequently asked questions

Where can I buy 5SY4614-7 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time.

What is the breaking capacity of 5SY4614-7?

10 kA per EN 60898 for standard final-circuit duty, and 35 kA per IEC 60947-2 for industrial switchgear applications. The higher figure gives fault-current headroom where the upstream supply can deliver more than 10 kA.

What is the width of 5SY4614-7?

72 mm, which is 4 modular width units on a standard DIN-rail panel.

Will 5SY4614-7 drop into a panel specified around 5SY4304-7CV?

Both are 4-pole SENTRON MCBs with the same 72 mm width and DIN-rail mounting, so the physical footprint is identical. The difference is the rating: 5SY4614-7 is a 0.3 A C-curve; 5SY4304-7CV is a different rating and characteristic. Check the load current and tripping curve before substituting.
