Product details

The Siemens 5SU1324-6FR20 is a 2-pole RCBO from the SENTRON series, combining overcurrent and residual current protection in a single 36 mm wide unit.

At 40 °C it derates to 19.5 A, at 50 °C to 18.9 A, and at 60 °C to 18.4 A — so if the panel runs hot, size the upstream protection for the derated value, not the 30 °C figure.

Residual current and selectivity

The 30 mA trip threshold is the standard for personal protection against electric shock. The super resistant K design indicates enhanced immunity to nuisance tripping from surge currents and voltage transients — useful on lines with switching power supplies or motor drives.

Depth is 72 mm, installation depth 70 mm — confirm the gland plate clearance if the board is shallow.

Frequently asked questions

Where can I buy 5SU1324-6FR20 and how do I get a price?

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

What is the closest functional second-source to 5SU1324-6FR20?

The closest functional second-source is the 5SU9304-1KK32, also a 2-pole RCBO from the SENTRON series. The 5SU1324-6FR20 uses a B-curve and 30 mA residual current; the 5SU9304-1KK32 uses a different characteristic curve and residual current rating — verify the specific trip coordination and sensitivity before substituting.

What is the depth of 5SU1324-6FR20?

The depth is 72 mm, with an installation depth of 70 mm.

What is the width of 5SU1324-6FR20?

The width is 36 mm, which is 2 modular width units on a DIN rail.
