A miniature circuit breaker rated 30 amps with Z-curve tripping for single-pole circuit protection
The Schneider Electric miniature circuit breaker is rated at 30 amps with a Z-curve trip characteristic for sensitive electronic loads. Its single-pole design protects one live conductor in residential or light-commercial distribution boards. The device is supplied new and carries the manufacturer’s 2020 listing date.
At 30 amps the breaker comfortably handles continuous loads up to its rated current while the Z curve provides fast magnetic tripping for short-circuit protection of delicate equipment. It will not suit circuits requiring higher ampacity or multi-pole isolation for three-phase supplies.
The defining parameter is the Z-curve trip profile combined with a 30-amp single-pole rating, which determines whether the breaker matches the inrush and fault-current profile of the protected circuit. Verify the curve and pole count against your design before ordering.

The Z curve trips only at very high instantaneous currents, so it will not nuisance-trip alongside existing B or C curve devices; set discrimination by ensuring the upstream breaker has a higher magnetic threshold.
Switch the toggle to ON, verify voltage on the load terminal with a multimeter, then press the integral test button — if fitted — or apply a calibrated overload to confirm the thermal trip operates at 30 A.
The breaker body includes the DIN-rail clip and captive terminal screws; separate lugs or busbar combs are only needed if your panel uses a different connection style.
