Quick answer: Eaton contactors switch motor and power circuits on and off from a control signal. This guide covers 10 models, from the compact XTCD9-11 (9A, AC-3) to the DILM150(RDC24), a 75 kW contactor with a 24-27V DC coil. Choose by motor power or current (AC-3 rating), coil voltage, auxiliary contacts and the protection you pair it with. Shansen Traders, an authorized Eaton channel partner in Coimbatore, lists all ten on KovaiGuide.
If you run pumps, compressors, fans or conveyors, you already depend on contactors. The challenge is choosing the right one from model codes like XTCD40-11 or DILM150(RDC24). This guide explains what each Eaton contactor is rated for, which coil voltage to pick, and how a contactor fits with your MCCB and overload protection. It compares ten Eaton contactors available through Shansen Traders in Coimbatore.
What Is a Contactor and What Does It Do?
A contactor is an electrically operated switch. When its coil is energised, it pulls the power contacts closed and the load starts. When the coil is de-energised, the contacts open and the load stops. Contactors are built for frequent switching, which is why they start and stop motors, pumps and compressors every day. They give you three things:
- Remote switching: a push-button, timer, PLC or float switch controls the coil, while the contacts carry the heavy motor current.
- Frequent operation: contactors are designed for many thousands of switching operations.
- Safer control circuits: a low-voltage control signal (for example 24V DC or 230V AC) switches the main power circuit.

Why a DC coil helps: a 24-27V DC coil, as on the DILM150(RDC24), can be driven straight from a PLC output or a 24V control supply. The built-in suppressor circuit protects the control electronics from voltage spikes when the coil switches off.
How to Choose the Right Eaton Contactor in 6 Steps
Step 1: Match the rating to your motor
Check the motor’s full-load current or kW rating at your supply voltage, then choose a contactor whose AC-3 rating is above it. For example, the XTCD25-11 is listed at 11 kW at 380V, and the XTCD95-11 at about 45 kW.
Step 2: Pick the utilisation category
AC-1 is for resistive loads such as heaters. AC-3 is for starting and stopping squirrel-cage motors. AC-4 is for harsher duty such as inching and plugging. If the motor is inched or plugged (reversed while it is still running), choose a contactor rated for AC-4, such as the XTCD40-11 or DILM150(RDC24).
Step 3: Choose the coil voltage and type
Match the coil to your control supply. A 230V AC coil suits standard push-button control. A 24V DC coil suits PLC-driven panels. Several models here offer coil options, so quote the exact coil voltage when you enquire.
Step 4: Check auxiliary contacts
Most of the XTCD models listed here have 1NO+1NC auxiliary contacts built in. These are used for latching (hold-in) circuits and status signals. Confirm you have enough for your control logic.
Step 5: Pair it with protection
A contactor switches but does not protect. Always pair it with a short-circuit protective device (an MCCB or MCB) and an overload relay. Read our Eaton MCCB guide to size the breaker.
Step 6: Consider mounting and environment
Check whether you need DIN-rail or panel mounting, the ambient temperature (the XTCD65-11 is listed for -25°C to +60°C), and the protection degree. IP20 means finger-safe inside a panel, and IP00 on the DILM150 means it must be mounted inside a protected enclosure.
Contactor vs MCCB: What Is the Difference?
A contactor is built to switch a load on and off many times a day under normal conditions. An MCCB is built to protect: it trips on overload and short circuit and isolates the circuit, but it is not meant for frequent switching. In a motor feeder they work together: the MCCB protects the circuit, the contactor switches the motor and an overload relay protects the motor.

Frequently Asked Questions About Eaton Contactors
1. What is a contactor used for?
A contactor is an electrically operated switch used to start and stop motors, pumps, compressors, fans, heaters and other power loads from a control signal. It is built for frequent switching.
2. What is the difference between a contactor and an MCCB?
A contactor switches a load on and off during normal operation, but it does not protect the circuit. An MCCB protects against overload and short circuit and isolates the circuit, but it is not designed for frequent switching. A motor feeder normally uses both, plus an overload relay.
3. What does AC-3 mean on a contactor?
AC-3 is the utilisation category for starting and stopping squirrel-cage induction motors. A contactor’s AC-3 rating tells you the motor current or power it can switch, so it is the main rating to match to your motor.
4. How do I choose the coil voltage for an Eaton contactor?
Match the coil to your control supply. Use a 230V AC coil for standard AC control circuits, and a 24V DC coil (as on the DILM150(RDC24)) when a PLC or 24V DC supply drives the contactor. Quote the exact coil voltage when you order.
5. Which Eaton contactor suits an 11 kW motor?
The Eaton XTCD25-11 (SKU CMD00537) is listed as a 25A contactor rated 11 kW at 380V. Always confirm against the motor’s full-load current and the Eaton datasheet before ordering.
6. Which Eaton contactor is for motors above 45 kW?
The Eaton Moeller DILM150(RDC24) (SKU 239591) is a 3-pole contactor rated 75 kW at 380-400V, with a 24-27V DC coil and categories AC-3, AC-4 and AC-1.
