—

Remote control

The direct action motor operator available for XT1 and XT3 is supplied:
• with 1m long cables;
• with a flange, to replace the standard one supplied with the circuit-breaker;
• with a padlock device, only removable when the motor is in the open position. The padlock device ac-
cepts up to three 8 mm padlocks;
• auxiliary contacts (AU-MO), which allow the motor control mode (manual or auto) signal to be routed
outside;
• (on request) the motor operator can be fitted with a key lock (see the Chapter "Accessories" - section
"Locks").
Operating principles:
• a selector on the front of the MOD, is used for selecting the operating mode:
- AUTO: when the selector is in this position, the circuit-breaker closing is commanded remotely only
by means of an electric impulse, whereas opening is allowed both remotely and from the front of the
motor;
- MANUAL: when the selector is in this position, the circuit-breaker can only be opened/closed from
the front of the motor by means of the relative lever housed in a slot made in the motor itself;
• via remote control, guaranteed by permanent electrical opening/closing impulses.
