Product details

Integrator note — 5SY3116-7

Breaking capacity is 4.5 kA per EN 60898 and 6 kA per IEC 60947-2, so it fits residential and light commercial panels where the prospective fault current stays under those thresholds. At 72 V DC maximum, the DC breaking capacity rises to 15 kA per IEC 60947-2 — useful for control-circuit protection in DC bus applications.

Wiring and terminal detail

Both top and bottom terminals are combined (screw and clamp), and the breaker is sealable for anti-tamper applications. Touch protection is built in (IP20 with connected conductors).
