Product details

At 2 A this MCB protects a 2 A branch circuit; derate to 1.92 A at 40 °C and 1.79 A at 55 °C if the panel runs warm. The 4-pole configuration switches all four lines —, L2, L3, and N — with no neutral switching, meaning the neutral pole is a switched pole but not a fused function. The 10 kA SCCR is the same under both EN and IEC standards, so it meets the common grid fault level for most commercial sub-distribution boards.

Touch protection is built in.

The SENTRON series is a standard Siemens MCB line, so documentation (declaration of conformity, RoHS, REACH) is available on request for your quality pack.

Frequently asked questions

What is the breaking capacity of 5SL4402-6?

It is rated 10 kA under both EN 60898 and IEC 60947-2, matching the standard fault level for most commercial sub-distribution.

Will 5SL4402-6 drop into a panel specified around 5SL3640-7MB without rewiring?

The 5SL4402-6 is a 4-pole B-curve 2 A MCB, while the 5SL3640-7MB is a different variant — check the pole count, current rating, and tripping characteristic of the existing part before swapping. Footprint (DIN rail, 4 MW) is the same, but the electrical ratings must match the circuit design.

Where can I buy 5SL4402-6?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial offer.
