Schneider Lc1F185 Contactor

Product Detailed Description:

The Schneider Electric LC1F185 is a Contactor from the LC1F series. Specifically, it is designed as a Contactor/Relay combination unit. This device integrates a single-pole contactor rated for 25 A and a single-pole changeover (SPDT) relay rated for 16 A. It is commonly used in control panels and automation systems where both higher current switching (via the contactor) and lower current control switching (via the relay) are required in a compact, DIN rail mountable package. The “F” in the series typically denotes features like a fixed front connection and potentially other specific characteristics of the LC1F family.

Product Parameters (Typical for LC1F185 - always check datasheet for exact values):

• Contactor Part:

• Number of Poles: 1P (Single Pole)

• Rated Current (AC-3): 25 A

• Rated Voltage: Typically 230/400 V AC

• Coil Voltage Options: Various options available (e.g., 24V AC/DC, 120V AC, 230V AC, 400V AC - specific to model variant)

• Mechanical Life: Typically millions of operations

• Electrical Life (AC-3): Typically hundreds of thousands to millions of operations depending on load

• Relay Part:

• Number of Poles: 1P (Single Pole)

• Contact Type: Changeover (SPDT - Single Pole Double Throw)

• Rated Current: 16 A

• Rated Voltage: Typically up to 250 V AC / 30 V DC

• Coil Voltage: Usually the same as the contactor coil, but functionally separate.

• General:

• Mounting: DIN Rail

• Enclosure Type: Usually supplied without an enclosure; intended for panel mounting or use within an existing enclosure.

• Weight: Approximately 250 grams (check datasheet for exact weight)

Product Advantages:

• Space Saving: Combines the functions of a contactor and a relay in a single compact unit, saving valuable panel space compared to using separate devices.

• Cost-Effective: Reduces the number of components needed, potentially lowering overall system cost and simplifying procurement.

• Simplified Wiring: Fewer devices mean less wiring complexity, reducing installation time and potential for errors.

• Integrated Solution: Provides both power switching (contactor) and control signal switching (relay) capabilities within one device, which can be convenient for certain control logic applications.

• Reliability: Utilizes Schneider Electric’s proven contactor and relay technologies.

• Standard Compliance: Designed to meet relevant international standards (e.g., IEC).

Precautions / Notes:

• Coil Voltage: Ensure the coil voltage matches the control circuit voltage exactly. Applying incorrect voltage can damage the device.

• Load Type and Rating: Do not exceed the rated current and voltage for either the contactor or relay parts. The contactor is typically rated for AC-3 loads (motors), while the relay contacts are suitable for resistive loads. Consult the datasheet for specific load type ratings (AC-1, AC-3, DC).

• Wiring: Follow the wiring diagram carefully to avoid incorrect connections, which could lead to malfunction or damage.

• Installation: Ensure proper mounting on a suitable DIN rail and secure connections.

• Environment: Install in an environment within the specified operating temperature and humidity ranges, away from excessive vibration, dust, or corrosive agents unless specifically rated for such conditions (e.g., specific IP rated enclosures if used).

• Disconnection: The contactor part provides main power switching, while the relay part is for control signals. Ensure proper disconnection procedures are followed during maintenance.

Product Applications:

• Motor Control Panels: For switching motors (using the contactor) and controlling indicators, solenoids, or other control circuits (using the relay).

• Automation Systems: Where a single device is needed to handle both a motor load and provide auxiliary switching functions.

• Control Panels: General-purpose control tasks requiring both power contactors and signal relays in a confined space.

• Lighting Control Panels: Switching lighting loads (contactor) and controlling dimmers or other control elements (relay).

• Pump and Compressor Controls: Managing the main power and providing status signals or interlocks.

• Heating, Ventilation, and Air Conditioning (HVAC) Systems: Controlling compressors, fans (contactor) and managing thermostats, zone valves, or alarms (relay).
