Breaking capacity hits 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V — so it handles high-fault scenarios downstream of a transformer or generator tie without cascading upstream.
Rated for the Nacelle Environment
The 248 x 138 x 110 mm (9.76 x 5.43 x 4.33 in) footprint fits standard panel cutouts; the 37.5 W max power loss is manageable in a sealed enclosure with basic ventilation.
At 415 V, the 121 kA breaking capacity gives headroom for high-fault installations — useful when coordinating with upstream transformers or generators. Trip indicator is present; undervoltage release and ground-fault monitoring are not fitted on this variant.
