The Eaton DILM115 is a high-performance power contactor belonging to the DILM series, which is part of Eaton's xStart system. It is primarily used for switching electric motors and other resistive or inductive loads in industrial and commercial applications.

Product Specifications

Designation: Power Contactor
Eaton Series: DILM (part of the Moeller legacy)
Rated Operational Current ( $I_{\text{e}}$ ):

AC-3 (Motor Switching): $115 \text{ A}$ at $380 \text{ V}$ to $440 \text{ V}$
AC-1 (Resistive Load): $160 \text{ A}$ at $690 \text{ V}$

Rated Operational Power (AC-3): $55 \text{ kW}$ at $380 \text{ V}$ to $400 \text{ V}$ (Standard 3-phase motor power)
Number of Poles: 3-pole main contacts
Auxiliary Contacts: Includes one integrated Normally Open (NO) and one integrated Normally Closed (NC) auxiliary contact (Often designated DILM115-(24VDC), DILM115-(230VAC), etc., where the voltage indicates the coil control voltage).
Control Voltage ( $U_{\text{c}}$ ): Available in various $\text{AC}$ and $\text{DC}$ coil voltages (e.g., $24 \text{ VDC}$ , $110 \text{ VAC}$ , $230 \text{ VAC}$ )
Terminal Type: Screw terminals for main and auxiliary circuits.
Degree of Protection: $\text{IP00}$ for the terminals; $\text{IP20}$ with terminal covers.
Mounting: $\text{DIN}$ rail mountable or screw fixing.
Ambient Temperature: Suitable for operation typically from $-25^{\circ}\text{C}$ to $+60^{\circ}\text{C}$ .

Product Advantages

High Performance and Reliability: The DILM series is known for its robust and reliable switching capability, ensuring long service life for motor control applications.
Compact Design: Despite its high current rating of $115 \text{ A}$ , the contactor offers a relatively compact footprint, saving space in control cabinets compared to older generations of contactors.
Integrated Auxiliary Contacts: The built-in $1 \text{ NO} + 1 \text{ NC}$ auxiliary contact set reduces the need for external auxiliary contact blocks in many standard applications, simplifying wiring and reducing costs.
Standardized Accessories: It is part of the extensive DILM family, sharing common accessories like thermal overload relays, auxiliary contact blocks, and mechanical interlocks across different frame sizes, simplifying inventory management.
Safety Features: Features like integrated mirror contacts for safety circuits enhance its suitability for applications requiring functional safety.

Important Considerations (Precautions)

Coil Voltage Check: Always verify the specific control voltage ( $U_{\text{c}}$ ) of the contactor coil before installation, as using an incorrect voltage will immediately damage the coil or prevent the contactor from operating correctly.
Appropriate Load Rating: Ensure that the contactor's $\text{AC-3}$ rating ( $115 \text{ A}$ ) meets or exceeds the motor's full-load current. For heavy-duty motor starting or special loads, consider using a higher $\text{AC}$ utilization category or derating the contactor.
Thermal Overload Protection: The DILM115 contactor must be paired with an appropriate thermal overload relay (e.g., ZB series) sized according to the motor's service current to provide essential protection against overheating and mechanical damage.
Correct Wiring Torque: Tighten all screw terminals to the manufacturer-specified torque to ensure a solid electrical connection and prevent overheating or loosening under vibration.
Environmental Conditions: While robust, ensure the operating environment stays within the specified temperature and humidity ranges, and always install the contactor within an appropriate enclosure to achieve the desired $\text{IP}$ protection level.

Product Applications

The Eaton DILM115 Contactor is widely used across various industries for demanding motor switching and power control applications.

Motor Control Centers (MCCs): Employed in control panels to switch large three-phase motors driving pumps, fans, compressors, and conveyors.
Heating and Lighting: Switching high-current heating elements or large banks of lighting, typically utilizing the $\text{AC-1}$ rating.
Power Distribution: Used in transfer switch applications or for isolating power circuits.
Machinery Control: Integrated into industrial machinery like presses, mixers, and processing equipment to control high-power actuators.
Reversing Motor Applications: Two DILM115 contactors can be mechanically and electrically interlocked for controlling the forward and reverse rotation of a large motor.
