It carries an ETU320 LI trip unit with a nominal current In = 250 A, overload protection adjustable Ir = 100 A to 250 A, and short-circuit protection Ii = 1.5 to 10 × In. The N-conductor protection is adjustable (OFF, 50%, 100%). An integrated undervoltage release (24 V DC) is included as an accessory for 3VA1 and 3VA20 frames, plus one auxiliary contact. The ETU320 LI electronic trip unit provides adjustable long-time (overload) and instantaneous (short-circuit) protection curves, letting you dial in Ir between 100 A and 250 A to match cable or busbar ampacity. The adjustable N-conductor protection (OFF, 50%, 100%) is useful for 4-wire systems where neutral current monitoring is required by code or design. This is a 4-pole IEC frame 250 breaker — mounts in a standard switchboard or panel enclosure with busbar or cable connections. The included nut keeper kit simplifies torque-verified lug installation. The undervoltage release (24 V DC) is factory-integrated; verify coil polarity before energizing. The auxiliary contact provides a status signal for PLC or SCADA monitoring. No DIN-rail mounting — this is a bolted-frame breaker for fixed or draw-out chassis.","metaTitle":"Siemens 3VA2225-6HL42-0BF0 Circuit Breaker, 250A, 85kA @ 415","metaDescription":"Siemens 3VA2225-6HL42-0BF0 IEC frame 250 circuit breaker, 85kA breaking capacity at 415V, 4-pole, ETU320 LI trip unit, 250A.
