Description

Product Overview

The SCHIELE DL42N-22 is a professional-grade,three-pole motor contactor engineered for demanding industrial environments.As a critical component in motor control circuits,its primary function is to establish or interrupt the power supply to three-phase AC motors.This is achieved by energizing a coil,which creates a magnetic field that mechanically pulls a set of contacts together.When the coil is de-energized,the contacts open,safely cutting power to the motor.The robust design of the DL42N-22 allows it to handle high operational currents and voltages,making it ideal for a wide range of motor sizes and applications.

The DL42N-22 is part of a legacy product line known for its durability and reliability.Originally from the German manufacturer SCHIELE,this series was later incorporated into the Entrelec and ABB/Entrelec product family,maintaining its reputation for quality.Its rugged construction ensures a long mechanical and electrical life,even under frequent switching cycles.The design also allows for the easy addition of auxiliary contacts,overload relays,and other accessories,providing flexibility and comprehensive motor protection within a compact footprint.

Expandable and Flexible Design:The modular nature of the DL42N-22 allows for the easy integration of a variety of accessories.Additional auxiliary contact blocks,thermal overload relays,and surge suppressors can be quickly attached,enabling the creation of custom control circuits with enhanced protection and functionality.

Safety and Reliability:The contactor provides a safe means of controlling machinery remotely,protecting personnel from live circuits.Its design conforms to international standards,ensuring reliable operation and safe isolation of the motor from the power source when needed.

Application Field

The SCHIELE DL42N-22 is a versatile component found in a multitude of industrial and commercial applications.Its robust design makes it an ideal choice for:

Manufacturing and Automation:Used in the control panels of machine tools,conveyors,pumps,and fans to reliably start and stop motors as part of automated processes.

HVAC Systems:Employed in large commercial and industrial HVAC units to control the compressors and fan motors,ensuring efficient and stable climate control.

Pumping Stations and Water Treatment:Deployed in water and wastewater facilities to control the motors of pumps and mixers,which are essential for fluid transfer and process management.

Material Handling:Critical for controlling the motors on cranes,hoists,and conveyor systems in warehouses and logistics centers.

Related Products

The SCHIELE DL42N-22 is part of a larger system of motor control components.Related products often used alongside it include:

SCHIELE Thermal Overload Relays:These devices are mounted directly to the contactor to provide protection against motor overheating due to overcurrents.

SCHIELE Auxiliary Contact Blocks:Snap-on blocks that add more normally open and normally closed contacts for signaling and interlocking.

SCHIELE Motor Starters:Complete assemblies that combine the DL42N-22 with an overload relay and an enclosure.

Push Buttons and Indicator Lights:Used on a control panel to provide a human interface for operating the contactor.

Motor Protection Circuit Breakers:Devices that offer both overcurrent and short-circuit protection for the motor circuit.

Installation and Maintenance

Pre-installation

Before installing the SCHIELE DL42N-22,always ensure that the power supply to the control panel is disconnected and locked out.Mount the contactor securely using either the DIN rail clip or the screw mounting holes.Connect the main power wires to the terminals marked L1,L2,L3,and the motor wires to T1,T2,T3.Connect the control circuit power to the coil terminals(typically A1 and A2)according to the specified coil voltage.Verify all connections are tight and secure to prevent arcing and ensure a reliable connection.

Maintenance

The DL42N-22 is a durable,low-maintenance component.Routine maintenance should involve:

Visual Inspection:Regularly inspect the contactor for any signs of physical damage,overheating,or discoloration of the terminals.

Dust and Debris Removal:Keep the contactor clean from dust and other industrial contaminants that could interfere with its operation or heat dissipation.

Terminal Tightness Check:Periodically re-torque the terminal screws to ensure connections remain secure,as vibration can cause them to loosen over time.

Status Monitoring:Listen for any unusual buzzing or humming sounds,which may indicate a coil or contact issue.The smooth,decisive”click”of the contactor pulling in and dropping out indicates normal operation.
