Product details

Siemens 3VA1225-5EF42-0AA0 — 250 A SENTRON MCCB, 4-Pole, TM240 Release

Breaking capacity is specified per voltage: 187 kA at 240 V AC, 121 kA at 415 V AC, 75.6 kA at 440 V AC, 30 kA at 500 V AC, and 17 kA at 690 V AC. Continuous current rating holds at 250 A from 40 °C through 50 °C ambient, then derates linearly to 223 A at 70 °C. The TM240 release is fixed-trip, not adjustable; the breaker's minimum breaking capacity is 1 250 A. Dimensions are 70 mm depth, 140 mm width, 158 mm height. Maximum power loss is 57 W.

Installation and Panel Fit

No undervoltage release, voltage trigger, or communication function is integrated — this is a standalone line-protection breaker. Ground-fault monitoring is not included.
