Product details

At 1.6 A it protects a branch circuit drawing about 0.7 kVA at 400 V three-phase. Breaking capacity of 10 kA at 400 V AC (per EN 60898 and IEC 60947-2) covers most residential and light commercial service-entrance fault levels in European 400/230 V networks. The 3-pole design switches all three phases simultaneously, which matters for three-phase motor or distribution subfeeds. Rated for 50/60 Hz supply, maximum operating voltage 440 V AC multi-phase, and DC rated up to 72 V.

Snap-on DIN rail mount, any position. Sealable with a lead seal or lockable cover — useful for utility-metered or tamper-evident circuits.

Frequently asked questions

What is the breaking capacity of 5SL4315-7?

10 kA at 400 V AC under both EN 60898 and IEC 60947-2 — the same rating for residential and industrial fault-current duty.

Will 5SL4315-7 drop into a panel specified around 5SL4363-7?

Yes — same 3-pole C-curve footprint, same 54 mm width, same 76 mm depth, same DIN-rail mounting. The only difference is the current rating: 1.6 A vs 63 A on the 5SL4363-7. No rewiring or panel modification needed if the branch circuit load matches the lower rating.

Where can I buy 5SL4315-7?

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