The SENTRON 3VA2340-6HN32-0CC0 is a 3-pole molded case circuit breaker rated for 400 A continuous current at 40–50 °C, with a maximum breaking capacity of 242 kA at 240 V AC. The unit measures 138 mm wide × 248 mm high × 110 mm deep, fitting standard panel cutouts for this frame class.
At 415 V and 440 V the rating holds at 187 kA, dropping to 121 kA at 500 V and 7.5 kA at 690 V.
The 138 mm width and 110 mm depth fit standard MCCB panel cutouts for this frame class; the 248 mm height requires clearance for the rotary handle and auxiliary switch wiring. The undervoltage release (UVR) is factory-installed — verify coil voltage matches your control circuit before panel wiring. The two HQ auxiliary switches provide status feedback for PLC or SCADA inputs. Maximum power loss of 98.5 W should be factored into enclosure thermal calculations, especially in sealed cabinets.
