Product details

Mounting position is any, which helps when the enclosure layout is tight.

Environmental and electrical ratings

Ambient temperature range is -40 °C to 75 °C, with humidity derating up to 95% at 55 °C, 55% at 70 °C, and 35% at 75 °C. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, so it holds up on a machine frame or in a mobile installation.

Supplementary devices and approvals

The UL/CSA breaking capacity is 5 kA per UL 1077 and CSA C22.2 No. 235 — a step down from the IEC 6 kA, so check the label if the panel is destined for a North American job site.

Frequently asked questions

How do I get current pricing and availability for 5SY6302-8CC?

Submit an RFQ through this listing. The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time.

Will 5SY6302-8CC drop into a panel that was specified around 5SY4304-7CV without rewiring?

Both are 3-pole MCBs on a 54 mm wide DIN-rail footprint, so the mechanical fit is the same. The 5SY6302-8CC has a D-curve and 2 A rating; the 5SY4304-7CV is a C-curve at a different current. If the original panel was wired for a C-curve, the D-curve changes the trip coordination — check the load's inrush profile before swapping. No rewiring of the busbar or terminals is needed.

What compliance documentation does the brand provide for 5SY6302-8CC?

The part carries IEC 60898 ratings (6 kA breaking capacity) and UL 1077 / CSA C22.2 No. 235 ratings (5 kA). It is halogen-free and silicon-free, which supports RoHS and REACH compliance. The manufacturer provides a declaration of conformity and the relevant test certificates upon request.
