It carries an 800 V rated insulation voltage and delivers a 440 kA interrupting capacity at 240 V, tapering to 52.5 kA at 690 V — meaning it can safely clear high-fault currents on the line side without upstream coordination issues.
That's useful when the breaker sits next to heat-generating contactors or drives. The 3-pole block occupies three module widths on a DIN rail. The breaker includes summation-current ground-fault monitoring on the line conductor — a built-in detection feature that can reduce external GFCI hardware in grounded-wye systems. No undervoltage release or communication module is fitted on this variant.
