Product details

The IP20 enclosure suits enclosed distribution boards only — not exposed washdown areas.

The 80 A rating holds at 40 °C ambient; at 45 °C it derates to 77.57 A, and at 55 °C it drops to 70.22 A. The 100 mA trip is for equipment protection or submain feeders, not personnel shock protection (30 mA is the standard for that). The 0.8 kA rating under EN 60898 is a lower conditional rating for domestic boards — in industrial panels the 10 kA figure governs.

Panel integration

Snap-on DIN rail (REG) mount, any position. Depth is 70 mm, width 72 mm (4 MW), height 90 mm. Supply feeds from top or bottom. Silicon-free construction. The IP20 rating requires the distribution board to be installed and conductors connected — open-panel mounting is not permitted.

Frequently asked questions

What is 5SV4447-0 used for?

It is a residual current circuit breaker (RCCB) for AC systems at 50 Hz, providing earth leakage protection on 4-pole circuits up to 80 A with a 100 mA trip threshold. Typical use is submain feeder or equipment protection in industrial distribution boards.

Where can I buy 5SV4447-0?

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

Will 5SV4447-0 drop into a panel specified around 5SL4363-7 without rewiring?

Both are 4-pole DIN-rail devices in the SENTRON family, but the 5SL4363-7 is a miniature circuit breaker (MCB) with a different function and trip curve — it is not a direct mechanical or functional substitute for an RCCB. The 5SV4447-0 occupies the same 4-MW footprint, so the physical slot fits, but the circuit protection role is different.

What compliance documentation does Siemens provide for 5SV4447-0?

The part is designed to IEC 61008-1 and EN 60898. Silicon-free construction is confirmed. RoHS, REACH, and UL documentation should be requested at quote time — the evidence does not list specific cert numbers.
