Product details

No undervoltage release or communication module is fitted, so this is a straightforward standalone breaker for basic feeder protection.

The 3VA1125-4EE42-0AA0 delivers 121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, and 11.9 kA at both 500 VAC and 690 VAC. For a site electrical engineer coordinating a panel, the 121 kA figure at 240 V gives headroom for high-fault installations near a large transformer; the 11.9 kA at 690 V is typical for industrial motor circuits at that voltage.

The 101.6 mm width (4 inches) is the standard footprint for a 4-pole MCCB in a SENTRON panel — it fits the same busbar and mounting pattern as other 4-pole 3VA frames.

Frequently asked questions

How do I get current pricing and availability for 3VA1125-4EE42-0AA0?
