Product details

Breaking capacity and standard coverage

The 5SY6650-7: The dual breaking capacity rating covers the two main installation standards: 6 kA under EN 60898-1 (household-type coordination) and 10 kA under IEC 60947-2 (industrial coordination). For UL-marketed panels, it also carries a 5 kA rating per UL 1077 and CSA C22.2 No. 235. That means the same part works across European and North American spec sheets — one SKU for multi-site BOMs.

Mounting position is unrestricted — vertical, horizontal, or upside-down in the panel — which simplifies layout in tight enclosures. The combined terminal design (top and bottom) accepts the same conductor range without needing separate neutral bars for the N pole.

Rated for ambient temperatures from -40 °C to +75 °C, with humidity derating above 55 °C (max 95% RH at 55 °C, tapering to 35% at 75 °C). Sealable enclosure (tamper-proof cover) available.

Frequently asked questions

What breaking capacity does 5SY6650-7 have?

Rated 6 kA per EN 60898-1, 10 kA per IEC 60947-2, and 5 kA per UL 1077 / CSA C22.2 No. 235.

Will 5SY6650-7 drop into a panel specified around 5SY6332-7CC?

The 5SY6650-7 is a 4-pole (3P+N) unit at 72 mm wide (4 MW), while the 5SY6332-7CC is a 2-pole unit at 36 mm wide (2 MW). They share the same SENTRON platform and DIN-rail mounting, but the pole count and width differ — the 5SY6650-7 will not fit a panel wired for a 2-pole without re-terminating the neutral and freeing two additional module spaces.

Who supplies 5SY6650-7 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
