Overload relays are used to protect the motor from overheating by monitoring the current flowing through the contactor. The contactor coil is connected to the power supply and is responsible for opening and closing the main contacts. Each CLM contactor has an electronic control module Forward / reverse starters will come with two sets of normally open auxiliary contacts to act as holding contacts in each direction. Auxiliary contact. Using the test button, it is possible to test the control wiring. Check Jul 22, 2022 · An auxiliary contactor diagram consists of two main parts: the main contactor and the auxiliary contactors. 1. Coils can be changed quickly, without a tool, on the Type DPA, 50–90 A contactors. Relays are typically reserved for use with loads of around 5A-15A, and they are most often rated for 10A or less; Contact standards. for Contactor right side mtg . Sizes 3-7 contactors use a Class 9999 SX6 auxiliary contact as the holding circuit contact. The basic circuit and its operation is the same as the diagram on Page 6. Some contactors provide an auxiliary output contact as a signal to the isolated part of the circuit that the contactor has been energized. A normally close auxiliary contact from both star and delta contactors (5&6)are also placed opposite of both star and delta contactor coils, these interlock contacts serves as safety switches to prevent simultaneous activation of both star and delta contactor coils, so that one cannot be activated without the other deactivated first. Each contact in a Ladder Diagram PLC program represents the reading of a single bit in memory, while each coil represents the writing of a single bit in memory. Multiple auxiliary contacts can be mounted to electrical devices.
