Product details

Mounts in any position, which simplifies layout in a crowded enclosure. The IP20 rating applies with conductors connected — standard for inside a distribution board where no washdown or outdoor exposure exists.

Thermal derating and ambient range

Rated 6 A at 30 °C ambient; derates to 5.58 A at 40 °C and 5.4 A at 45 °C. If the panel runs warm — say, near a transformer or in a sealed enclosure — account for that drop when sizing the load.

Construction and compliance notes

Halogen-free and silicon-free construction, which matters if the panel serves sensitive environments (medical, clean room) where outgassing from a fault could contaminate nearby equipment. The neutral conductor is switched, so the breaker disconnects both phase and neutral — required in many single-phase final circuits for full isolation.

Frequently asked questions

Where can I buy the 5SL6506-7MB and get a price?

The 5SL6506-7MB is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the depth of the 5SL6506-7MB?

The body depth is 76 mm, with an installation depth of 70 mm behind the panel face.

What is the width of the 5SL6506-7MB?

It occupies 2 modular width units, which is 36 mm on a standard DIN rail.

Will the 5SL6506-7MB drop into a panel specified for the 5SL6550-7BB?

Both are 2-module-width SENTRON MCBs on the same DIN-rail footprint, so the mechanical fit is identical. Check the tripping characteristic and rating — the 5SL6506-7MB is a C-curve 6 A, while the 5SL6550-7BB is a B-curve at a different current rating, so the protection curve differs.

What compliance documentation does Siemens provide for the 5SL6506-7MB?

The breaker is designed to EN 60898 and IEC 60947-2, carries an IP20 rating, and is halogen-free and silicon-free. Standard Siemens documentation includes a declaration of conformity covering the applicable EU directives; specific RoHS and REACH declarations are available from Siemens on request.
