Schneider Electric TeSyS D Mechanical Latch Accessory for LC1D LP1D LA6DK20F

Schneider Electric LA6DK20F is a mechanical latch accessory specifically designed for seamless integration with LC1D and LP1D contactors within the TeSys D series. This mechanical latch block ensures the armature remains closed upon coil energisation, maintaining the contactor state during interrupted power cycles.

This functionality permits power consumption reduction by allowing de-energisation of the contactor coil without losing the contactor's state. The device can be actuated remotely or manually through the provided front panel button, enhancing operational convenience.

To ensure correct performance, the electrical delatching pulse duration must exceed 100 milliseconds. The maximum permissible on-time for the unlatch coil is limited to 30 seconds as it is not designed for continuous use, with a maximum operation frequency capped at 36 cycles per hour to maintain device longevity.

The mechanical latch block is designed for front panel mounting, simplifying installation and maintenance. Users must ensure that the unlatch coil and the associated contactor or relay are never energized simultaneously to avoid equipment damage.

This mechanical latch block engages upon coil energisation to hold the armature closed. Maintains contactor state during power interruptions and reduces coil power consumption. Remote actuation or front panel button operation facilitates versatility.

Electrical delatching pulse must be greater than 100 milliseconds to operate properly. Maximum unlatch coil on-time is 30 seconds; not rated for continuous duty. Maximum operation frequency is 36 cycles per hour. Front panel mounting design for convenient installation.

Unlatch coil and contactor/relay must not be energized simultaneously.

This accessory is suited for use in industrial automation, electrical control systems, and manufacturing environments where reliable contactor state retention and energy efficiency are critical.
