Our GV4PEM Circuit Breakers have a setting range for their protection values; Isd, In or Class. Within that range, there are specific increments that can be set, either by using the setting dials on the front, or the GV4 mobile app (depending on the protection type).

Isd Protection (Short Circuit)

Isd protection is set using the GV4 mobile app and has a setting range of 5x...13x Ir. The setting increment is 0.5x. This means that you can set it to 5x, 5.5x, 6x, etc. but you can't set it to 5.25x, 5.75x, 6.25x.

Ir Protection (Overload)

Ir protection is set using a front dial and the setting range depends on the Circuit Breaker. The table below shows the setpoint values that are available for selection for the different breaker sizes (In):

Class Setting
Class setting is selected using a front dial, and you will have 2 positions: Class 10E and Class 20E. There are no other setpoints for this setting.
