The 3-pole design uses an ETU850 electronic trip unit, giving you adjustable protection curves and a communication function for monitoring or remote trip coordination. Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V. At 690 V the 7.5 kA rating drops, but that's typical for this frame class; for 690 V applications you coordinate upstream to stay under that threshold.
Mounting and integration into a panel
That 110 mm depth is the overall body — factor in handle throw and cable bending radius when you lay out the gland plate. Communication is onboard, so you can wire it into a BMS or PLC for remote status and trip logging without adding an accessory stack.
