Product details

Four poles let it switch all three phases plus neutral in a 3-phase sub-distribution board, though note it does not switch the neutral internally (neutral conductor switching is not a function of this unit).

At 40 °C it derates to 0.48 A, at 45 °C to 0.46 A, and at 55 °C to 0.44 A. If your panel runs warm — common in a crowded enclosure or near a heat source — factor the derating into your load calculation.

The sealable design lets you lock the toggle in the ON or OFF position with a padlock — useful for lockout/tagout on a dedicated circuit.

Frequently asked questions

What is the breaking capacity of 5SL6405-7?

6 kA per both EN 60898 and IEC 60947-2 at 400 V AC. That is the standard breaking capacity for this series — adequate for most residential and light commercial sub-distribution boards.

What is the tripping characteristic and what loads is it for?

C-curve, meaning magnetic trip between 5 and 10 times the rated current (0.5 A). It is designed for moderate inrush loads such as small motors, lighting circuits, and control transformers where a B-curve would nuisance-trip but a D-curve is not needed.

What compliance documentation does Siemens provide for 5SL6405-7?

The part is halogen-free and silicon-free, which supports compliance with RoHS and REACH requirements. It carries IEC 60898 and IEC 60947-2 ratings. Specific declarations are available on request with the RFQ.

How do I get current pricing and availability for 5SL6405-7?

Submit an RFQ through this listing. We source the part to order and confirm availability and current pricing at quote time — no automated stock figures here, because the market moves daily on a standard catalog MCB like this.
