Product details

Siemens SENTRON 5SL3201-7MB — 1 A C-Curve 2-Pole MCB

It breaks fault currents up to 4.5 kA per EN 60898 and 5 kA per IEC 60947-2, making it suitable for residential and light commercial distribution boards where short-circuit levels stay within those limits. The C curve means it tolerates moderate inrush — typical for small motor or lighting loads — without nuisance tripping.

Halogen-free and silicon-free construction. Sealable for tamper-proof installations. Mechanical service life typically 20 000 switching cycles.

Frequently asked questions

What is the breaking capacity of the 5SL3201-7MB?

Rated breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 at 400 V AC.

Will the 5SL3201-7MB drop into a panel specified for the 5SL3340-7CC?

Both are SENTRON MCBs on the same DIN-rail footprint with identical depth (76 mm) and height (90 mm). The 5SL3201-7MB is 2-pole (36 mm wide) versus the 5SL3340-7CC's 3-pole (54 mm wide). Physically it fits the same rail but occupies less width; wiring must match the 2-pole configuration.

Where can I buy the 5SL3201-7MB?

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