Product details

What this MCB carries

At 400 V AC it interrupts 30 kA per IEC 60947-2, with a DC rating of 15 kA at 72 V and a UL 1077 / CSA 22.2 No. 235 interrupting capacity of 5 kA. The D-curve means the magnetic trip activates at 10–20× rated current, so it holds through the inrush of a small motor or transformer bank without nuisance tripping. The 76 mm depth leaves clearance behind a standard 100 mm deep gland plate. IP20 with conductors connected; touch protection built in.

Integration notes

The sealable option (lockable toggle) lets the panel builder lock out a circuit for lockout/tagout without an external hasp. Ambient range -40 °C to 75 °C covers cold storage and hot roof-top enclosures; humidity derating applies above 55 °C (max 95% RH at 55 °C, tapering to 35% at 75 °C).

Frequently asked questions

What is the interrupting capacity of 5SY8413-8 at 400 V AC?

30 kA per IEC 60947-2 at 400 V AC. At DC (72 V) it is 15 kA; under UL 1077 / CSA 22.2 No. 235 it is 5 kA.

Will 5SY8413-8 drop into a panel specified around 5SY4140-7 without rewiring?

Both are 4-pole SENTRON MCBs on the same DIN-rail footprint, so the mechanical swap is direct. But the 5SY4140-7 is a B-curve 40 A device; the 5SY8413-8 is D-curve 13 A — the trip characteristic and current rating are different, so verify the branch circuit protection requirements before substituting.

Where can I buy 5SY8413-8 and how is it quoted?

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