That spread means it can serve as a main breaker on a 480 V panel or a feeder breaker in a 690 V industrial system, though at higher voltages the available fault current must stay under 17 kA. The 3VA1112-5ED42-0AA0 measures 101.6 mm wide, 130 mm tall, and 70 mm deep — a compact 4-pole footprint that fits standard distribution panelboards. Maximum power loss is 28.1 W, which matters for thermal budgeting in a sealed enclosure.","metaTitle":"Siemens 3VA1112-5ED42-0AA0 SENTRON MCCB, 125 A, 4-Pole, 187","metaDescription":"Siemens 3VA1112-5ED42-0AA0 SENTRON molded case circuit breaker, 125 A at 40 °C, 4-pole, TM210 release, 187 kA at 240 V.

The deciding difference is the overcurrent release: the 5ED42-0AA0 uses a TM210 thermal-magnetic release, while the 5EE32-0AA0 uses a different release variant.
