Masterpact NW circuit breakers and switch disconnectors may be installed in various switchboards and horizontal mounting plates. Each system has its own installation method of these breakers and the tightening torque needs to be adapted by the panel builder considering the screw size. The mounting plate is horizontal and the role of those bolts and nuts is to avoid circuit breaker movement.
Nevertheless, the torque usually applied on such M8 class 8.8 bolts and nuts is < 25Nm.
