Breaking capacity steps down with system voltage: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. That 52.5 kA at 690 V is the figure to check for 690 V line-side fault duty — it's well above typical industrial service-entrance requirements but confirms the breaker can handle a high-fault 690 V bus without cascading upstream.
Trip unit and protection features
Neutral protection is configurable: OFF or 100% of the phase rating. No undervoltage release or shunt trip is fitted, so if you need remote tripping, plan on an external UVR or shunt module. Communication function is absent — this is a standalone breaker, not a power-monitoring node.
Dimensions are 181 mm high, 140 mm wide, 86 mm deep — a 4-pole frame that fits standard SENTRON 3VA panel cutouts.
