Schneider Electric TeSyS D Mechanical Latch Block for Use with LP1D, LC1D LA6DK20B

Schneider Electric LA6DK20B is a mechanical latch block from the TeSyS D series, designed specifically for use with LP1D and LC1D contactors. This device engages mechanically upon coil energisation, holding the armature in a closed position to maintain the contactor state.

This function is critical in industrial automation and electrical control systems where maintaining contactor status after interrupted cycles is necessary. It also helps reduce power consumption by allowing the contactor coil to be de-energised during operation pauses.

The mechanical latch can be actuated either remotely or by a front panel button, providing flexible control depending on the application setup. The device is designed for front panel mounting, simplifying installation and maintenance in automation panels.

The latch requires an electrical delatching pulse exceeding 100 milliseconds for proper operation. It is important to note that the unlatch coil and the contactor or relay should never be energised simultaneously, preventing damage and ensuring longevity.

Operational limits include a maximum on-time of 30 seconds, as it is not rated for continuous duty, and a maximum operation frequency of 36 cycles per hour. These specifications make the LA6DK20B suitable for various industrial automation scenarios, including manufacturing, building management systems, and other control gear applications.

The mechanical latch engages on coil energisation to maintain contactor armature closure. Designed for power savings by allowing coil de-energisation during hold. Front mounting type for easy installation in control panels.

Remote actuation or front panel manual button operation available. Electrical delatching pulse must exceed 100 ms for latch release. Not suitable for continuous operation; max on-time is 30 seconds. Maximum operating frequency is 36 cycles per hour.

Made in France, ensuring high quality and durability.

This mechanical latch block is part of the broader Schneider Electric TeSyS D range, renowned for industrial automation reliability and efficiency. It fits within the electrical, automation, and control gear categories, making it a fundamental component in control and relay assemblies.
