Product details

Breaking capacity and selectivity

The 3VA2040-6JP46-0AA0: The 242 kA interrupting rating at 240 V and 187 kA at 415 V provide substantial fault-current headroom for main or feeder positions in high-capacity distribution. At 500 V the rating drops to 121 kA, and at 690 V it is 3 kA — the latter limits application to low-fault systems or downstream positions at that voltage.

Thermal performance and trip unit

The 40 A continuous rating holds across the full ambient range from 40 °C to 70 °C, meaning no derating is needed in a warm enclosure. The ETU550 electronic trip unit supports adjustable long-time, short-time, instantaneous, and ground-fault protection curves, enabling selective coordination with downstream breakers.

Physical integration

At 181 mm high, 140 mm wide, and 86 mm deep, this 4-pole MCCB fits standard SENTRON mounting patterns. The IP40 front protection means it is suitable for installation in a dry indoor panel or enclosure with a sealed door.

Frequently asked questions

What are the key ratings of 3VA2040-6JP46-0AA0?

Continuous current 40 A, 4-pole, ETU550 electronic trip unit, breaking capacity 242 kA at 240 V and 187 kA at 415 V, insulation voltage 800 V, IP40 front protection.

What is the closest functional second-source for 3VA2040-6JP46-0AA0?

The peer MPNs 5SQ2670-2YA63 and 5SQ2670-2YA16 are functionally similar SENTRON MCCBs, but physical fit and trip-unit features should be verified before substituting into an existing panel design.
