The D-curve (tripping characteristic class D) means the magnetic trip fires between 10× and 20× In — so 60 to 120 A instantaneous — which is why this breaker is the go-to for motor feeders, solenoid valve banks, and UPS input circuits where startup current can hit 8–12× running load. The 30 mA trip threshold (tripping fault current rated value 30 mA) provides personal protection against direct contact; it's the standard for socket-outlet circuits in most IEC countries. Thermal derating is real on this unit: at 40 °C ambient the 6 A rating drops to 5.64 A, at 50 °C it's 5.22 A, and at 55 °C it's 4.86 A. The insulation voltage (Ui) is rated 264 V, and overvoltage category III suits fixed-installation distribution boards downstream of the main panel. Surge voltage resistance is 4000 V, which covers most industrial transient environments.
Depth is 77 mm, installation depth 70 mm — check your enclosure depth if you're retrofitting into a shallow gland box. The IP20 rating applies only when the distribution board is installed with connected conductors — this is a panel-internal device, not a weatherproof field unit. Touch protection is built in (product feature touch protection yes). Pollution degree 2 (non-conductive dust only) is typical for clean industrial or commercial environments.
