Miniature auxiliary contactor, 4NO/0NC, 230VAC control DILER-40-EA(230V50HZ,240V60HZ) 189973

Miniature auxiliary contactor – reliable circuit control

This miniature auxiliary contactor from Eaton, model DILER-40-EA, is a component designed to expand control circuits. It finds application in both industrial installations and commercial and residential buildings. Its compact dimensions (45 mm wide, 58 mm high and 52 mm deep) allow for easy mounting in tight spaces. The design allows for mounting on a DIN rail or with screws, providing installation flexibility.

Functionality and operating parameters

This contactor is characterized by four normally closed auxiliary contacts (4Z) and no normally open contacts (0R), making it an ideal solution for applications requiring reliable switching of auxiliary circuits. It is designed to operate with a control voltage of AC 230V (50Hz) or 240V (60Hz), as well as with DC voltage in the range of 24-220V. The rated operating current is 10A, and at 400V – 3A, ensuring safe and efficient operation in various conditions. The method of connecting the auxiliary circuit is based on a screw connection, guaranteeing stable and reliable electrical connections.

Applications and benefits

The DILER-40-EA contactor performs perfectly in applications requiring frequent circuit switching, such as:

• Lighting control
• Alarm systems
• Building automation
• Electric motor control (as an auxiliary element)
• Expansion of existing control systems

Its versatility results from the possibility of powering with both alternating current (AC) and direct current (DC). The lack of an LED indicator simplifies the design and minimizes the risk of interference in operation. Solid construction and high quality workmanship ensure long-lasting and trouble-free operation of the device. The rated switching current of 10A allows for servicing devices with higher power consumption during start-up.
