Product details

Siemens SENTRON 5SL6320-7CC — 20 A, 3-Pole, C-Curve MCB

The Siemens SENTRON 5SL6320-7CC is a 3-pole miniature circuit breaker rated for 20 A at 400 V AC, with a C tripping characteristic and a 6 kA breaking capacity according to EN 60898. The IP20 protection class (with connected conductors) suits it for installation inside distribution boards in residential buildings and infrastructure applications. The 6 kA breaking capacity at 400 V AC is the value per EN 60898, the residential and commercial standard; for industrial installations requiring IEC 60947-2 ratings, the sibling 5SL4363-7 carries a 10 kA rating under both standards.

The sealable design allows panel locks for tamper-proof installations.

Rated for an ambient temperature range of -40 °C to 75 °C, with a vibration resistance of 50 m/s² at 25 to 150 Hz per IEC 60068-2-6. Halogen-free and silicon-free construction.

Frequently asked questions

What is the breaking capacity of the 5SL6320-7CC?

The 5SL6320-7CC has a 6 kA breaking capacity according to EN 60898 at 400 V AC.

Where can I buy the 5SL6320-7CC?

The 5SL6320-7CC is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the difference between the 5SL6320-7CC and the 5SL4363-7?

Both are 3-pole C-curve MCBs with the same physical dimensions (76 mm depth, 54 mm width, 90 mm height). The 5SL4363-7 has a higher breaking capacity — 10 kA per both EN 60898 and IEC 60947-2 — versus 6 kA per EN 60898 for the 5SL6320-7CC. The 5SL4363-7 also has a higher power loss of 5 W per pole versus 3.5 W. Panel cutouts and wiring are identical; the choice depends on the required fault current rating.
