Product details

Snap-on quick assembly system to DIN rail; mounting position any. Operating temperature range -40 °C to 75 °C, with humidity limits of max 95% at 55 °C, 55% at 70 °C, 35% at 75 °C.

The product is halogen-free and silicon-free. Sealable. Designed per DIN EN 61346-2 (function code F). The manufacturer provides standard compliance documentation including RoHS and REACH declarations; UL and IEC certifications are typical for the SENTRON series but should be verified against the specific variant at time of order.

Frequently asked questions

Who supplies 5SY5202-6CC12 and how is it quoted for volume purchases?

This part is sourced through independent distribution channels and quoted to order against an RFQ. Volume pricing and lead time are confirmed at quote time; no stock figures are published here.

Will 5SY5202-6CC12 drop into a panel that was specified around 5SY5250-7 without rewiring?

Both are 2-pole SENTRON MCBs with the same 36 mm width and 76 mm depth, so the mechanical footprint is identical. However, the 5SY5202-6CC12 is a 2 A B-curve DC-rated device, while the 5SY5250-7 is a 50 A unit — verify the load current and trip characteristic before swapping; the panel wiring and protective device coordination must match the new rating.

What is 5SY5202-6CC12's listed depth (76 mm) on this component line?

The depth is 76 mm, with an installation depth of 70 mm.

What is 5SY5202-6CC12's listed width (36 mm) on this component line?

The width is 36 mm, which corresponds to 2 modular width units on a DIN rail.

What compliance documentation does this brand provide for 5SY5202-6CC12 (RoHS, REACH, UL, IEC)?

The manufacturer provides standard RoHS and REACH declarations; UL and IEC certifications are typical for the SENTRON series but should be confirmed against the specific variant at time of order.
