Its 32 A rated current (In) and C-curve magnetic trip (5 to 10 x In) mean it is sized for general-purpose distribution circuits feeding mixed resistive and moderate-inductive loads, such as lighting, socket outlets, and small motorized equipment, where the C-curve provides tolerance for inrush without nuisance tripping. The 30 mA earth-leakage sensitivity (IΔn) provides personnel protection against direct contact, per the requirements of IEC 60364 for socket-outlet circuits and final subcircuits in residential and commercial installations. Integrated earth-leakage protection means no separate RCCB module is needed upstream — this single unit handles both overcurrent and ground-fault detection. Breaking capacity is 6 kA Icn / Icu at 380–415 V AC, 50 Hz, conforming to EN/IEC 61009-2-1 and EN/IEC 60947-2. This is the standard interrupting rating for final distribution boards in most European domestic and light commercial panels. For installations with higher prospective fault current, selectivity with an upstream MCCB or fuse must be verified. The thermal-magnetic trip unit provides time-delayed overload protection (thermal bimetal) and instantaneous short-circuit protection (magnetic solenoid). Limitation class 1 per EN/IEC 61009-2-1 means the device limits let-through energy to a level that protects downstream wiring under fault conditions.
Deployment and integration
Clip-on mounting to DIN rail (EN 60715) with a 9 mm pole pitch. The 4-pole unit occupies 8 x 9 mm = 72 mm of rail width. IP40 in a distribution enclosure, IP20 for the terminals — suitable for installation within a panel or consumer unit. Local signalling via toggle position: ON, OFF, and fault-trip indication. The toggle provides manual control and visual status at the panel face.
Quality labels include KEMA-KEUR, NF, IMQ, and VDE — these marks certify compliance with the applicable EN/IEC standards and are accepted across most European and many international regulatory jurisdictions.
Durability and environmental ratings
These figures reflect the expected service life under rated load conditions and are consistent with a premium RCBO intended for distribution duty.
