Product details

The Siemens 5SY7301-8CC is a 3-pole miniature circuit breaker from the SENTRON 5SY7CC series, rated 1 A at 400 V AC with a D tripping characteristic. Under UL 1077 and CSA C22.2 No. 235 it carries 5 kA, so it's accepted in North American supplementary protection roles.

Deployment and integration

The combined terminals top and bottom accept solid or stranded wire from 0.75 to 35 mm²; tightening torque is 2.5 to 3.5 N·m. It's rated IP20 with connected conductors, so it belongs inside an enclosed panel, not out in a washdown zone.

Frequently asked questions

How do I get current pricing and availability for 5SY7301-8CC?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time; we source through independent distribution and can quote to your required quantity and delivery window.

What is the closest functional second-source to 5SY7301-8CC?

The 5SY3132-6 is a 3-pole, 1 A, D-curve MCB in the same SENTRON family. It shares the same DIN-rail footprint and 54 mm width, so it can drop into an existing panel without rewiring. The main difference is the breaking capacity — the 5SY7301-8CC carries 50 kA IEC versus the 5SY3132-6's lower rating — so check your available fault current before substituting.

Will 5SY7301-8CC drop into a panel specified around 5SY3132-6 without rewiring?

Yes, both are 3-pole, 54 mm wide, DIN-rail mounted MCBs with the same terminal wire range (0.75–35 mm²). No rewiring needed for the mechanical fit. But verify the D-curve and breaking capacity match your circuit's requirements.

What compliance documentation does Siemens provide for 5SY7301-8CC?

The breaker is designed to IEC 60947-2 (50 kA) and UL 1077 / CSA C22.2 No. 235 (5 kA). It carries overvoltage category III and is rated for 50/60 Hz. The product is halogen-free and silicon-free. Standard Siemens declarations (CE, UKCA, RoHS, REACH) are available through the Siemens Industry Online Support portal.
