Product details

Siemens 5SY7606-8 — SENTRON MCB, 6 A, D Curve, 4P

The Siemens 5SY7606-8 is a 4-pole (3P+N) miniature circuit breaker from the SENTRON 5SY7 series, rated at 6 A with a D tripping characteristic at 400 V AC. Breaking capacity is 15 kA per EN 60898 and 40 kA per IEC 60947-2, with a 5 kA rating under UL 1077 / CSA C22.2 No. 235. That 40 kA IEC figure gives you headroom for high-fault installations; the 15 kA EN rating covers the standard domestic/commercial panel spec.

Mounting and wiring — panel fit

Touch protection is built in; the unit is sealable. Ambient range -40 to +75 °C operating, storage -40 to +70 °C. Halogen-free and silicon-free construction, so it won't outgas corrosive compounds in sensitive environments like data centers or medical equipment.

Suitable for mechanical engineering and industrial applications per the manufacturer. Overvoltage category III, pollution degree unspecified but typical for this class. Compliance with EN 60898 and IEC 60947-2 is listed; UL 1077 / CSA C22.2 No. 235 recognized for the 5 kA AC rating. The product is classified as F per DIN EN 61346-2 and DIN EN 81346-2.

Frequently asked questions

What is the breaking capacity of 5SY7606-8?

15 kA per EN 60898 and 40 kA per IEC 60947-2 at 400 V AC. For DC circuits, it's rated 15 kA at 72 V per IEC 60947-2. Under UL 1077 / CSA C22.2 No. 235, the AC breaking capacity is 5 kA.

Will 5SY7606-8 drop into a panel designed for 5SY6602-8?

Both are 4-pole SENTRON MCBs on the same DIN-rail footprint (72 mm wide, 4 width units), so the mechanical fit is identical. The difference is in ratings: 5SY7606-8 is 6 A D curve; 5SY6602-8 is a different current/curve variant. Check your branch circuit's required ampacity and coordination before swapping.

What compliance documentation is available for 5SY7606-8?

The MCB carries EN 60898 and IEC 60947-2 ratings, plus UL 1077 / CSA C22.2 No. 235 recognition for the 5 kA AC rating. It is halogen-free and silicon-free. Standard Siemens SENTRON documentation (declaration of conformity, CE marking) applies; specific certificates are available on request at quote time.
