Product details

SENTRON 3VA1140-5EF36-0AA0 — 40 A MCCB with TM240 Release

Its TM240 thermal-magnetic release is set for a continuous current of 40 A at 40 °C, with a derating curve that holds 40 A up to 50 °C, then drops to 39 A at 55 °C and 37 A at 70 °C — useful to know when the breaker is packed into a warm enclosure. Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V.

The width is a standard 3-inch (76.2 mm) footprint for a 3-pole MCCB — fits the usual panel cutout and bus bar spacing.
