Product details

4-pole C-curve MCB for 400 V distribution

Rated 4 A at 30 °C, but the 5SL4404-7 derates to 3.84 A at 40 °C and 3.58 A at 55 °C. If your panel ambient runs at 40 °C (common in a sealed enclosure), the breaker's effective rating drops 4% — factor that into the load calculation. The device is rated for ambient up to 75 °C and down to -40 °C, with 95% humidity at 55 °C.

Mounting position is unrestricted. IP20 with connected conductors — fine inside a distribution board but not for wet locations.

Frequently asked questions

What is the 5SL4404-7 rated breaking capacity?

10 kA per EN 60898 and also 10 kA per IEC 60947-2.

What is the difference between 5SL4404-7 and 5SL4363-7?

The 5SL4363-7 is a 63 A C-curve 4-pole MCB versus the 4 A rating on this part. Both share the same SENTRON platform and physical footprint — same 4-module width, same 10 kA breaking capacity. The swap is a straight drop-in if the load current allows it, but the 4 A version is the correct choice for a 4 A branch circuit.

Where can I buy 5SL4404-7 and get a price?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.
