Motor control contactors

Art. DILMT

Eaton-Moeller's DILMT series contactors are compact devices for use in mechanical engineering. DILMTs can be used in a wide range of applications thanks to their efficiency and space-saving design. Available in four compact sizes, these contactors cover a current range from 7 to 95 A and can be used to start motors up to 45 kW or to switch industrial loads. In addition to applications with resistive loads (AC-1), DILMT contactors can also be used to switch and protect asynchronous motors (AC-3) – in combination with ZBT overload relays. With a high number of operating cycles (up to 1,500,000), the DILMT contactor becomes a reliable and efficient component in any industrial installation or system.

Mini contactor DILE

Art. DILE

Thanks to their compact size, Eaton-Moeller DILE series mini contactors are suitable for applications requiring switching and control of small motors or loads. With extended certification, DILE are suitable for use worldwide. They are also ideal for harsh environments with high temperatures.

Key Features

AC drive - for control voltages from 24 to 600 V at 50 or 60 Hz
DC drive - for control voltages from 12 to 250 V
UL and CSA certifications
For controlling motors with power up to 5.5 kW
DC-controlled devices with built-in protection circuits
Auxiliary NC mirror contact for use in security systems
Low power consumption = can be controlled directly by PLC

Mini contactors are available in three versions: 4 NO contacts; 3 NO contacts and 1 NC contact; and 2 NO contacts and 2 NC contacts. These devices can also be expanded to eight contacts. All contacts are reversible and equipped with a locking device.

Power contactors DILM/DILH

Art. DILM/DILH

Eaton-Moeller's DILM and DILH series contactors are designed for very high currents from 185 to 2600 A. Their electronically controlled coils, compact dimensions, and long service life make these contactors a reliable component in any machine or system.

Key Features

Utilization category AC 1 and AC 3
Suitable for voltage up to 1000 V
Wide range AC/DC coil
Low holding power
Compact size
Auxiliary contacts: 2 NO, 2 NC

Contactors from 185 to 225 A

Contactors rated from 185 to 225 A feature compact dimensions and reduced holding power. The standard coils are equipped with a built-in protection circuit and two auxiliary contacts: two normally open and two normally closed.

Contactors from 250 to 2600 A - standard version

Significantly lower heating inside the switchgear due to reduced power in holding mode. Furthermore, optimized contact operation increases their service life. The protection circuit already includes two normally open contacts, two normally closed contacts, and two auxiliary contacts.

Contactors from 250 to 2600 A - “comfort” version

Thanks to its low pull-in power, the "Comfort" version facilitates the installation of smaller regulating transformers. A wider voltage range than standard contactors ensures increased reliability during voltage fluctuations. The contactors can also be controlled directly from a PLC.

Contactors DILM 580 - 1400 A

Vacuum technology enables compact designs by preventing open arcs and the release of switching gases. Closer distribution of switchgear is possible, and distances to conductive parts can be reduced.

Double contactors DILM 1600 and DILH 2000-2600

Double contactors are supplied pre-assembled on a mounting panel. Current is distributed for each phase through two parallel vacuum tubes. The contactors are securely connected by two interlocked and controlled drives. They are synchronously controlled by electronic components.
