At 240 V it interrupts 330 kA; at 415 V and 440 V it holds 242 kA; at 500 V it's 187 kA; at 690 V it's 7.5 kA.
ETU550 trip unit — adjustable protection without swapping hardware
The ETU550 gives you adjustable long-time pickup and delay (tr from 0.5 to 25 s), plus short-time and instantaneous settings, all dialed in on the front face. No module swap needed for coordination studies. The N-conductor protection is adjustable from OFF through 20 % to 160 % of the phase setting, which covers both solidly-grounded and resistance-grounded systems.
Communication-ready — but check the option slot
The 3VA2325-7JP42-0AA0 supports communication functions (yes on that spec line), meaning it can accept a communication module for remote monitoring and trip indication. The ETU550 itself has the internal bus; you add the external module (PROFIBUS, PROFINET, Modbus) separately. No ground-fault monitoring version included — that's a separate variant if you need GF protection.
