277949 & DILM150-XHI31, Eaton Auxiliary Contact - 3NO/1NC, 4 Contact, Front Mount, 4 A ac, 10 A dc

Eaton 4 Pole Auxiliary Contacts For Use With The DILM System

Created and designed to function for standard applications, with high operational reliability with a long lifespan, these auxiliary contacts are suitable for use with a multitude of DILM motor contactors from the xStart system. The DILM range of contactors and auxiliary contacts are ideal for AC-4 jogging, ensuring continual operation for busy environments. This flexible generation of modular components benefits from technology advances for motor switching and control.

Eaton's auxiliary contacts offer several contact combinations and are front or right-hand side mountable depending on their design, no tools needed! Trip indication presents through a red short-circuit indicator on some components, allowing users to view a trip easily, other information is provided to the upstream programmable controller. Information provided includes "on/off" on the protective switch, "tripped" message for overload or short circuits, and "on/off" for the contact module.

Features and benefits:

• Front mount and side-mounted contacts available
• Compatible with the SmartWire-DT® communication system
• Identical sizes for AC and DC operated contactors
• Minimised heat dissipation - energy saving

For use with DILM40 - DILM150

Typical Applications

This range of auxiliary contacts can be used across a multitude of applications, users will commonly find these contact blocks being used within industrial applications such as electric motor starters, control systems, control, power circuits and electrical signalling equipment.

How do Auxiliary Contacts work?

An Auxiliary Contact block, or aux contact, is an electromechanical device that is mounted typically to contactors. They are physically connected to the contactor, with simultaneous activation and deactivation applying to both the contact block and the contactor at the same time.

Auxiliary contacts can be installed onto contactors either by front mounting, or side mounting. This is usually clear in the shape and size of the product, but please check the compatibility of your devices. Aux Contacts are really useful devices to aid in keeping an eye on the contactor.
