Connection of residual current device for 2-phase operation
The following 3 and 4-pole molded case circuit breakers equipped with a residual current
device can be operated in two phases (L to L) with 2-pole switching:
● Loadside residual current devices for 3VA1: RCD320 and RCD520
Permissible rated operational voltage: 127 – 480 VAC 50/60 Hz
● Side mounted residual current devices for 3VA1: RCD310 and RCD510
Permissible rated operational voltage: 127 – 480 VAC 50/60 Hz
● Loadside residual current devices for 3VA2: RCD820
Permissible rated operational voltage: 127 – 690 VAC 50/60 Hz
