It is a 4-pole unit designed for line protection, fitted with an ETU550 electronic overcurrent release. Breaking capacity is specified per voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. These figures define the fault-clearing capability at the respective system voltages — critical for selectivity coordination studies.
Thermal performance and installation
Dimensions are 86 mm depth, 140 mm width, and 181 mm height.
