Cut-off current

The Bulletin 140A-C2A manual motor starter limits short-circuit current Icc (prospective short-circuit current). ID is the maximum cut-off current (highest instantaneous value of the limited short-circuit current). This value is indicated in the following diagram as a function of the system short-circuit current.

Correspondingly the maximum forward i2 dt energy is limited. This value is indicated in the following diagram as a function of the system short-circuit current.

1) Operating Current of Thermal Releases:

The adjustable inverse bimetal trip reliability protects motors against overloads. The curve shows the mean operating current at an ambient temperature of 20 °C starting from cold.

In equipment at operating temperature, release time is less than or equal to release time from the cold state.

2) Operating Current of Magnetic Releases:

Electromagnetic instantaneous releases react at a fixed tripping current.

At the upper thermal release setting, this tripping current is 11 times the set current.

Current To Be Set:

Thermal releases meet the requirements for a thermal release of a starter in accordance with IEC 60947-4-1 f. If a different value is specified (such as reduced Ie in motors with an ambient temperature higher than 40 °C or a site altitude >2000 m above sea level), the rated operating current Ie must be adjusted.
