Product details

The 90 mm height fits standard distribution board cutouts. IP20 with connected conductors — finger-safe on the front, but the busbar area needs clearance from live parts. Mounting position is unrestricted, so it can be installed horizontally or vertically without derating the thermal trip.

Thermal derating and service conditions

Rated 10 A at 30 °C ambient; at 40 °C the continuous current must be limited to 9.24 A, and at 45 °C to 8.8 A.

Material and compliance notes

Sealable per the manufacturer's definition, meaning the breaker can be locked in the OFF position with a standard padlock hasp for lockout/tagout.

Frequently asked questions

What is the 5SJ6510-7FC rated breaking capacity?

6 kA per EN 60898 at 230 V AC. That is the standard for residential and light commercial distribution boards — it interrupts a fault up to 6,000 A without failing.

Will the 5SJ6510-7FC drop into a panel specified for the 5SL6220-7?

The 5SJ6510-7FC shares the same 36 mm width, 76 mm depth, and DIN-rail mounting as the 5SL6220-7, so it fits the same panel cutout and busbar arrangement. The key difference is that the 5SJ6510-7FC is a 1P+N design (switched neutral) versus the 5SL6220-7's 2P design (both poles switched). Verify that your panel's neutral bar and wiring scheme expect a switched neutral before substituting.
