Product details

The Siemens 5SL3302-7MB is a SENTRON miniature circuit breaker — 3-pole, C-curve, rated 2 A at 400 V AC, with a 4.5 kA breaking capacity per EN 60898.

Fit and panel integration

Sealable design allows padlocking the toggle in the OFF position for lockout/tagout. Supplementary devices (shunt trip, auxiliary contacts, alarm switch) can be snapped on the right side.

Halogen-free and silicon-free construction — no corrosive off-gassing if the breaker arcs internally, which matters for sensitive electronics sharing the enclosure.

Frequently asked questions

What is the breaking capacity of the 5SL3302-7MB?

The 5SL3302-7MB has a rated breaking capacity of 4.5 kA at 400 V AC according to EN 60898.

Where can I buy the 5SL3302-7MB?

The 5SL3302-7MB is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at the time of quote.

Will the 5SL3302-7MB drop into a panel specified around the 5SL4363-7?

Yes, both share the same 76 mm depth, 54 mm width (3 MW), and DIN-rail mounting. The 5SL4363-7 carries a higher 10 kA breaking capacity and a 63 A rating, so the 5SL3302-7MB is a direct physical fit but serves a lower-current, lower-fault-duty branch.
