Siemens 3VJ2 MCCB 250A, 4-Pole, 55kA, LSIG Microprocessor Trip Unit – 3VJ2225-8JQ42-0AA0

Product Description

The Siemens 3VJ2225-8JQ42-0AA0 is a SINOVA 3VJ2 microprocessor-based MCCB designed for reliable line protection in low-voltage power distribution systems. It features a 4-pole, 250A configuration with LSIG protection and 55kA Icu/Ics at 415V AC.

The microprocessor-based trip unit provides L (overload), S (short-time short-circuit), I (instantaneous short-circuit), and G (ground-fault) protection. The overload protection setting Ir is adjustable from 100A to 250A, allowing the breaker to be configured according to the connected load and protection requirements. Siemens' product information identifies this configuration as a 3VJ2 FS250 MCCB with 250A rated current and LSIG protection.

The MCCB uses a knob operating mechanism and is suitable for industrial distribution panels, switchboards, electrical control cabinets, OEM applications and other low-voltage power distribution systems.
