Up to 4 components can be connected to the three connection
terminals (phases). Each phase is protected by a separate overcurrent
circuit breaker. The front-side IEC power socket is also supplied via

side switches.

The switch contacts (AUX L1, L2, L3) are assigned to the overcurrent
circuit breakers (L1, L2, L3) on the front side. Each switch contact is
activated when the associated overcurrent circuit breaker is tripped.
When switched off, contact 1 is connected with contact 2; when
switched on, contact 1 is connected with contact 3.
