Product details

Snap-on quick assembly system mounts on standard DIN rail. Two width units (36 mm) for the 1P+N form factor — the neutral pole switches internally, so no separate neutral bar is needed in the panel.

Rated for ambient temperatures from -40 °C to 75 °C, with humidity derating: 95 % RH up to 55 °C, 55 % RH to 70 °C, 35 % RH to 75 °C. Halogen-free and silicon-free construction. Mechanical endurance is 10 000 switching cycles. Neutral conductor switching is integral — the 1P+N pole switches both phase and neutral, meeting disconnection requirements for single-phase final circuits.

Frequently asked questions

Where can I buy 5SY7501-7CC and get a price?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — send the quantity for a firm commercial offer.

What is the closest functional second-source to 5SY7501-7CC?

The 5SY7140-8CC is a higher-current variant (1.4 A vs 1 A) in the same 5SY7CC family, same C-curve, same 1P+N form factor. It will drop into the same DIN-rail footprint and panel cutout without rewiring, but the 1 A rating is the correct overcurrent protection for the original circuit — substituting a higher-rated breaker compromises conductor protection.

Will 5SY7501-7CC drop into a panel specified around 5SY7140-8CC?

Yes — same 36 mm width (2 width units), same DIN-rail quick-mount system, same 1P+N pole arrangement, same terminal positions. The only difference is the 1 A vs 1.4 A current rating. Physical fit is identical; no rewiring or busbar changes needed.

What compliance documentation does Siemens provide for 5SY7501-7CC?

The breaker carries IEC 60947-2 and UL 1077 ratings, plus CSA C22.2 No.235. Halogen-free and silicon-free construction is declared. Standard Siemens SENTRON documentation includes the EU Declaration of Conformity (CE), UKCA, and EAC for Eurasian markets. RoHS and REACH compliance is covered by Siemens' standard material declarations available through their Industry Online Support portal.
