Product details

Siemens 3VA2140-8KP46-0AA0 — SENTRON MCCB for Line Protection

Breaking capacity is rated at 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — figures that give the panel designer headroom for high-fault-current installations where SCCR coordination is critical.

Selectivity and Coordination for the Site Engineer

With a maximum frame rating of 480 A and a minimum setting of 60 A, this 4-pole MCCB covers a wide adjustment band for feeder protection. The ETU850 release allows the engineer to dial in the long-time, short-time, and instantaneous pickup values to achieve selective coordination with downstream breakers — critical for minimizing outage scope on a plant floor. Front-face protection class is IP40.

Dimensions are 86 mm depth, 140 mm width, and 181 mm height — a 4-pole footprint that fits standard SENTRON 3VA2 panel cutouts and busbar systems.

Frequently asked questions

What trip unit does this MCCB use?

It uses an ETU850 electronic overcurrent release, which supports programmable trip settings and communication functions for integration into monitored power distribution systems.

What are the physical dimensions of 3VA2140-8KP46-0AA0?

Depth is 86 mm, width is 140 mm, and height is 181 mm — a 4-pole footprint that fits standard SENTRON 3VA2 panel cutouts.
