Product details

It carries a 15 kA interrupting rating per EN 60898 and a 40 kA rating per IEC 60947-2, with a UL 1077 listing at 5 kA.

The 5SY7206-8 occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. The quick assembly system snaps onto the rail without tools.

This breaker is rated for ambient temperatures from -40 °C to 75 °C, with derating above 55 °C per the humidity influence table (max 95% RH at 55 °C, tapering to 35% at 75 °C). IP20 protection applies with connected conductors.

The 5SY7206-8 is certified to IEC / EN 60898-1 and IEC / EN 60947-2, with a UL 1077 and CSA C22.2 No. 235 listing. The sealable design allows panel builders to lock the toggle position after commissioning. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, so it holds up on machine-mounted subpanels.

Frequently asked questions

What is the 5SY7206-8 used for?
