The LAD6K10M is a mechanical latch block accessory made by Schneider Electric (part of the TeSys range) used with contactors and control relays for motor control and automation systems.

• Product Type: Mechanical latch block accessory
• Brand: Schneider Electric (also under Square D/TeSys series)
• Used With: TeSys D contactors (LC1D09 to LC1D65A) and control relays (LC1DT20 to LC1DT80A)

• Function: Provides latching and unlatching action to a contactor after the coil is energized. This means:

  ✔ When a control coil is powered, the latch engages mechanically and holds the contactor in the ON position.
  ✔ This reduces power consumption because the coil can be de‑energized after the latch engages.
  ✔ Unlatching can be done electrically or manually when required.

• Control Voltage: 220–240 V AC or DC for latch/unlatch action
• Mounting: Front clip‑on mounting on compatible contactor frame
• Compatibility: LC1D09…LC1D65A 3‑phase contactors, LC1DT20…LC1DT80A control relays
• Rated Insulation Voltage: ~690 V (IEC 60947‑5‑1 standard)
• Power for Activation: ~25 VA AC / ~30 W DC (typical)
• Mechanical Endurance: ~500,000 cycles (typical)
• Operating Rate: ~1200 cycles/hour

The latch block sits on the front of a compatible contactor. When the coil power is applied:

1. The latch engages and mechanically holds the contactor closed.
2. Once the latch has engaged, power to the coil can be cut off, saving energy.
3. To release the latch (unlatch), a control signal or manual action is used.

This mechanical holding makes it ideal for control circuits where you want a stable ON state without continuous coil supply.

• Motor control circuits in industrial automation
• Contactor control where energy savings are needed
• Systems where holding the contactor position without continuous coil power is required
• Switching applications in panels

• Mounts front‑clip to compatible contactors
• Connects via screw terminals
• Should be sized for the correct control voltage (220–240 V AC/DC)

LAD6K10M is a mechanical latch block accessory for Schneider Electric TeSys D contactors and control relays. It allows a contactor’s ON state to be mechanically held after coil energization, improving reliability and enabling coil power reduction in control systems.

The LADR0 is a time‑delay auxiliary contact block manufactured by Schneider Electric, designed to be used with TeSys contactors and control relays (like the LC1D series). It adds timed off‑delay switching functionality to a contactor, enabling delayed break of an auxiliary circuit after control voltage is removed.

• Type: Time‑delay auxiliary contact block
• Contact Configuration: 1 NO (Normally Open) + 1 NC (Normally Closed) auxiliary contacts
• Operation: Off‑delay (the contacts change state after a preset delay when de‑energized)
• Time Setting Range: ~0.1 – 3 seconds off‑delay
• Rated Operational Voltage: Up to 690 V AC
• Rated Thermal Current: ~10 A
• Mounting: Front clip‑on mounting on compatible TeSys contactors
• Connection: Screw clamp terminals for secure wiring
• Durability: High electrical and mechanical endurance (millions of cycles)
• Standards & Certifications: IEC 60947‑5‑1, UL, CSA, CCC, EAC certified; RoHS/REACH compliant

• Adding off‑delay timing to contactor control circuits
• Motor control panels where delayed release is required
• Automation systems requiring simple timing without PLCs
• Systems that need auxiliary signalling after contactor coil de‑energisation

When the control contactor coil is de‑energised, the LADR0’s off‑delay timer keeps the auxiliary contacts in their previous state for a pre‑set delay (0.1–3 s) before they change. This is useful for applications like controlled shutdown of auxiliary circuits or delayed indicator warnings.

• Simple timing addition without external timers
• Compact and plug‑on mountable design
• Reliable performance in industrial environments
• Reduces wiring complexity by integrating timing into the contactor assembly

The LADR0 is a compact time‑delay auxiliary contact block for Schneider Electric TeSys D/F contactors that provides 1NO + 1NC contacts with a selectable off‑delay (0.1–3 sec). It enhances control flexibility and simplifies timing functions in motor control and automation panels.

The Schneider Electric GZ1AN is an electric contact block used in various electrical control and signaling applications.
