On coil energisation the mechanical latch is engaged & holds the armature closed.This feature enables the contactors state to be maintained when re-starting after an interrupted cycle & allows power consumption reduction by enabling de-energisation of the contactor coil.

Remotely actuated or by front panel button
Electrical delatching pulse must be greater than 100ms
Front mounting

The unlatch coil & the contactor or relay must not be energised simultaneously. Maximum on time is 30 seconds (not continuously rated). Maximum operation frequency is 36 per hour.

TeSys Deca mechanical latch block, for LC1D09-D80A, LC1DT20-DT80A contactors and CAD control relays (except devices with low consumption coils). Electrical latching and unlatching is performed applying a 110-127V control voltage pulse (> 100ms in AC, 250ms in DC). Unlatching can be manually operated. Clip-on mounting on front of contactor, connection by screw terminals. For applications with high operating rates until 1200 cycles/hour. Multi standards certified (IEC, UL, CSA), Green Premium compliant (RoHS/REACh).

• Robust lifespan of 500,000 cycles for long-lasting operation
• Control circuit voltage range between 110 and 127V AC/DC for broad compatibility
• Maximum operating rate of 1200 cycles per hour for speedy switching

• Agricultural equipment
• Automotive manufacturing
• Conveyor systems
• Food production

This block is compatible with multiple contactors from the LC1 series, making it a versatile option.

For assembly in a snap, you can mount this latching block by simply clipping it to the front of your contactor.
