Product details

Integrator note — 5SY7204-7

The Siemens 5SY7204-7 is a 2-pole SENTRON miniature circuit breaker with C-trip characteristic, rated 15 kA per EN 60898-1 and 40 kA per IEC 60947-2 at 400 V AC. DC rating holds at 15 kA per IEC 60947-2 up to 72 V, so it also covers control-circuit protection on 60 V DC buses.

Fastens via the quick-assembly system — snaps onto DIN rail, any mounting position. Terminal top and bottom are combined (same clamp accepts busbar or wire), which simplifies panel wiring when feeding a common bus.

Frequently asked questions

What is the difference between 5SY7204-7 and 5SY4140-7?

The 5SY4140-7 is a 1-pole breaker (single pole, 18 mm wide) versus the 2-pole 5SY7204-7 (36 mm wide). The 5SY7204-7 carries higher interrupting ratings — 40 kA per IEC 60947-2 vs the 5SY4140-7's lower rating — so it fits industrial distribution boards where fault current is higher. They share the same C characteristic and SENTRON platform, but the 2-pole version also switches both line conductors, while the single-pole does not switch neutral.

What compliance documentation does Siemens provide for 5SY7204-7?

The breaker is certified to IEC/EN 60898-1, IEC/EN 60947-2, UL 1077, and CSA C22.2 No.235. It is halogen-free and silicon-free. Standard Siemens declarations of conformity (CE, UKCA) and the full datasheet are available with the product documentation package.

Where can I buy 5SY7204-7 and how is it quoted?
