Product details

2 A C-curve MCB for panel protection

For UL 1077 supplementary protection, the interrupting rating is 5 kA.

DIN-rail fit and panel integration

Mounting position any, so it works in vertical or horizontal panel layouts. Halogen-free and silicon-free construction matters in clean-room or food-bev panels where outgassing contaminates sensors.

Thermal derating and ambient limits

Rated 2 A at 35 °C ambient; at 40 °C it derates to 1.89 A, at 50 °C to 1.77 A, and at 55 °C to 1.71 A. If the panel runs hot — say, next to a drive or transformer — size the load accordingly. The breaker itself operates from -40 °C to 75 °C ambient, with humidity limits of 95% up to 55 °C, tapering to 35% at 75 °C.

Frequently asked questions

How do I get current pricing and availability for 5SY7302-7CC?

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

Will 5SY7302-7CC drop into a panel that was specified around 5SY4301-7CV without rewiring?

Both are 3-pole SENTRON MCBs on the same DIN-rail footprint, so the mechanical fit is the same. The 5SY7302-7CC is a 2 A C-curve; the 5SY4301-7CV is a different rating and characteristic — verify the branch circuit's load and coordination before swapping.

What compliance documentation does this brand provide for 5SY7302-7CC?

The SENTRON series carries IEC 60947-2 certification for the 50 kA breaking capacity and UL 1077 / CSA C22.2 No.235 for the 5 kA supplementary protection rating. The product is also classified per IEC 81346-2 and DIN EN 61346-2 as function F.
