The adjustable thermal-magnetic trip unit covers 375 A to 2500 A (the / range), letting you set the instantaneous pickup to match cable or busbar withstand without swapping the breaker body. At 240 V it interrupts 330 kA — that's utility-grade fault current, typical for a transformer secondary or a large UPS output. At 415/440 V it still holds 242 kA, dropping to 187 kA at 500 V and 4.5 kA at 690 V. Three-pole, with an undervoltage release (UVR) built in and a communication function plus other measurement function — so it can report trip events and load data back to a BMS or SCADA system without an add-on module. No auxiliary switch fitted, no ground-fault monitoring. The trip indicator is absent, meaning you rely on the UVR or communication module for remote trip indication.
