Product details

Integrator note

The 5SY3004-7KV is a SENTRON miniature circuit breaker — 1+N-pole, C-curve, rated 4 A at 230 V AC with a 4.5 kA breaking capacity per EN 60898. Depth at 70 mm clears most 80 mm deep enclosures; snap onto standard DIN rail.

If your panel's available fault current exceeds that, you need a higher-rated device — the 5SY4140-7 (10 kA per EN 60898, 15 kA per IEC 60947-2) is one such alternative. The 1+N configuration switches both phase and neutral; the neutral pole is a switching neutral, not a protected pole.

Frequently asked questions

Will 5SY3004-7KV drop into a panel specified around 5SY6006-7 without rewiring?

Both share the same 1+N-pole, C-curve, 70 mm installation depth, and standard-rail snap-on mounting. The 5SY6006-7 is a 6 A device with a 6 kA breaking capacity per EN 60898; the 5SY3004-7KV is 4 A, 4.5 kA. As long as the load and fault current are within the 5SY3004-7KV's ratings, it fits the same footprint and wiring scheme — no rewiring required.

Where can I buy 5SY3004-7KV?

The 5SY3004-7KV is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
