Eaton Contactor, 230 V ac Coil, 4-Pole, 9 A, 4 kW, 4NO, 400 V ac

Eaton's range of DILEM & DILEEM contactors are predominantly used in larger-scale operations, they are designed to provide a long mechanical and electrical life which in turn accomplishes reliability. Users will commonly find these contactors integrated within industrial buildings and factory installations, enabling automated processes of motors and resistive loads

Easier engineering through identical construction sizes for AC- and DC-operated contactors
Energy savings and higher packing density in control panel due to minimized heat dissipation
High wiring security through doubled box terminals
Less coupler relays: direct actuation from the PLC for contactors up to 32 A
Easy engineering through integrated suppressor circuits for DC
Wide operating temperature
Surface or DIN rail mounting
Ingress Protection Rating of IP20 on the contacts protecting against solid objects up to 12mm, - has no protection against water
Mechanical Interlock for use with DILE* Series 326-740 (does not prevent fitting of auxiliary contact blocks)

If you have asked yourself this question, rest assured you are not the only person that has wondered how contactors work. If you've wondered how do contactors differ from a relay? The following answer will also explain that. A contactor is essentially a relay, it holds very similar functions, but it is typically used in larger-scale applications. In most cases, a contactor is a switch that can be controlled remotely, specifically designed to switch a large amount of electrical power through its contacts.

Use this contactor from Eaton to repeatedly switch power to a circuit. It allows low voltages and currents to switch a higher-powered circuit on and off. You'll find contactors like this frequently used in automated large-scale office, commercial and industrial lighting setups. Minimal heat dissipation gives this unit a lower operating temperature, so you can achieve a higher packing density on your circuit board. The double-box terminal ensures greater wiring security and helps prevent conductors from accidentally working loose. This contactor's enclosure has an IP20 (ingress protection) rating, which means it's touch-proof and protected against objects larger than 12mm.

• High mechanical durability for greater longevity
• Protected against mechanical shock, enabling use in harsh operating conditions
• Provides short-circuit protection for improved electrical safety

The most common cause of contactor failure is when the contacts of the device become stuck or fused in one position. This is usually a result of an excessive inrush current or unstable control voltages.
