Wiring Precautions
- Power-off Operation: Cut off all power supplies and lock the circuit before wiring to prevent electric shock.
- Cable Selection:
Circuit principal: Copper conductors ≥6mm² are recommended for 60A loads.
Circuit de commande: Copper conductors ≥1mm² are recommended.
- Terminal Fastening:
Main contacts: Use a torque wrench to ensure the specified torque is achieved.
Control terminals: Tighten moderately (1.7Nm) to avoid terminal damage.
- Application of Auxiliary Contacts:
NO contacts are commonly used for self-locking control.
NC contacts are used for interlocking or fault indication.
Scénarios d'application
Control of industrial heating equipment (fours à résistance)
Main switch for lighting systems
On/off control of non-inductive loads
Power switching for star-delta motor starting (used with other contactors)
Mounting Methods of Schneider LC1DT60AM7 Contactor
Schneider LC1DT60AM7 contactor offers two standard mounting methods:
- Montage sur rail DIN (Recommended)
Suitable for quick installation and replacement in control cabinets, compatible with standard 35mm DIN rail (EN 60715 standard)
Mounting Steps:
- Align the rail clips on the back of the contactor with the upper edge of the 35mm DIN rail.
- Press the contactor downward while pushing it toward the rail until a “cliquez” le son est entendu, indicating the clips are locked in place.
Removal Method:
Gently pry the spring clips at the bottom of the contactor with a screwdriver and push it downward slightly to disengage from the rail.
- Direct Screw Mounting
Suitable for fixed installation scenarios without DIN rails
Mounting Steps:
- Use 3 M4 screws (spring washers and flat washers are recommended).
- Fix the contactor through the 3 mounting holes on its back: 2 at the top and 1 at the bottom.
- Tighten the screws with torque controlled within 3.1Nm to prevent housing damage.
Précautions d'installation
- Position and Orientation
Must be installed vertically (tilt angle ≤5°) to ensure the normal operation of internal mechanisms and heat dissipation.
The coil terminal A1 should face upward, complying with operational habits and visual indication requirements.
- Environment and Space
Select a dry and well-ventilated location, away from heat sources and humid areas.
Reserve sufficient space (≥100mm) for arc flash and heat dissipation to avoid damage to adjacent components.
- Exigences de mise à la terre
The metal mounting base must be properly grounded (PE) to ensure safety.
When using DIN rail mounting, the rail should be connected to an earthed conductive backplane.
- Wiring and Fixing
All terminals (including unused ones) must be tightened to ensure good contact.
Tightening torque for main circuit terminals: 8Nm for 25~35mm² cables; 5Nm for 1~25mm² cables.
Tightening torque for control circuit and auxiliary contact terminals: 1.7Nm.
The LC1DT60AM7 contactor provides flexible mounting options: 35mm DIN rail mounting is convenient and fast, suitable for standardized layout of control cabinets; M4 screw mounting is stable and reliable, applicable to special installation environments. Regardless of the method, vertical installation and good grounding must be ensured to guarantee the contactor’s performance and service life.
