When installing a PowerPact 4 MCCB onto the panel, the shear off bolts will shear when the correct torque setting has been reached - 20Nm for 100/160/250 frames and 28Nm for 400/630.
Refer to the instructions below, which are from the attached file.
A 17mm bi hex socket tool is required for removing the MCCB after the shear off bolts have been removed during first installation.
