Product details

The C curve means the magnetic trip operates at 5 to 10 times rated current (20–40 A for this 4 A unit), making it suitable for loads with moderate inrush — lighting banks, small transformers, or motorized valves. The 1 MW width (18 mm) is the standard single-module footprint, so it occupies one position on the DIN rail. The IP20 rating applies only when conductors are connected — the front face is touch-protected per the product feature, but the terminals are not sealed against dust ingress.

Integration notes

The supply can be fed from either end (top or bottom) — the position of the power supply cord is unrestricted. The neutral conductor is switched internally; no external neutral link is required.

Frequently asked questions

What is the breaking capacity of 5SY6004-7KL?

6 kA at 230 V AC per EN 60898, which is the standard rating for final subcircuit protection in residential and light commercial panels.

What is the difference between 5SY6004-7KL and 5SY6002-7KL?

The only difference is the rated current: 5SY6004-7KL is 4 A, while 5SY6002-7KL is 2 A. Both are 1P+N, C curve, 6 kA, 1 MW wide, and share the same physical dimensions and environmental ratings. They are direct drop-in replacements for each other in the same panel position, provided the load current matches.

Where can I buy 5SY6004-7KL?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What compliance documentation does Siemens provide for 5SY6004-7KL?

The part carries the SENTRON brand and is designed to meet EN 60898, IEC 60947-2, and UL 1077 standards. It is halogen-free and silicon-free. Specific declarations (RoHS, REACH, CE, UKCA) are available from the manufacturer upon request.
