The SENTRON 3VA2340-5JP32-0KL0 is a 3-pole molded case circuit breaker rated for 400 A continuous current at 40 °C, with a maximum breaking capacity of 187 kA at 240 V. At 415 V and 440 V it still clears 121 kA, and at 690 V it drops to 7.5 kA, which is typical for an MCCB of this frame size. The 400 A rating holds steady from 40 °C up to 50 °C, then derates linearly to 300 A at 70 °C. That means you get both status feedback and remote trip capability without adding external relay logic. The communication function is onboard, so it can talk to a BMS or PLC for power monitoring and remote control. The design is line protection — it's meant to sit at the feeder or sub-feed point, not downstream on a motor branch. The trip indicator and voltage trigger give clear visual and electrical fault indication, which cuts troubleshooting time when a line drops.
The breaker accepts lug or busbar connections on both line and load sides. No undervoltage release is fitted from the factory, so if your safety circuit requires UVR, you'll need to add it as a field-installable accessory.
