Contactor Overload Relays
What are Contactor Overload Relays?
The entire electric motor comes with a warranty to let them work reliably, efficiently, and safely. Since a protective system is our main concern, however, some causes happen with the failure of electrical overload, often referred to as overcurrent. As soon as a motor brings high voltage as compared to the designed to tackle its failures, the temperature develops a system consequence of overheating. Motor windings and coils are harmed by this. The motor and its circuit need to be protected, which is where connector overload relays might be useful. Schneider Electric, Siemens, ABB, Eaton, Lovato, and Rockwell Automation are just a few of the prestigious industry companies that offer a wide selection of high-quality connector overload relays.
What is Overload Safety?
Overload is usually referred to as a motor drawing a potential voltage over the rated value for a long time. Since they lead to overheating in the motor, which caused damage and failures in the system. In order to monitor or control such scenarios, devices like contactor relays are primarily manufactured for industrial control and automated motor protection. They are used with integrated contractors as a component of a machine starter and control board.
What are the Various types of Contactor Overload Relays?
Motor safety devices are categorized into two prime types such as thermal types and electronic types.
Thermal Relays:
The thermal overload relays make use of a bi-metallic plate situated immediately to the heating object. When a current excessively passes through the heating device Normally closed connection turns over and starts contacts. The interference power ranges from flowing to the connection's automated or control circuit. Typically, thermal overloads have a manual or automatic reset option as well as an adjustable current range.
Electronic Relays:
Electronic overload relays don't operate using a bi-metallic mechanism; instead, they measure the load current using parts like temperature sensors. They often have a larger current range and are more precise than thermal devices. A selectable trip class offers improved trip prevention against single phasing against the motor.

Contactor Relay
AF contactor relays are AC/DC operated
AF09-AF38 contactor relays include an electronic coil interface accepting a wide control voltage Ucmin - Ucmax. Only four coils cover control voltages 24 → 500 Vac or 20 → 500 Vdc
AF..Z contactor relays equipped with a Z coil type allow direct control by 24 Vdc, 500 mA PLC output and obtain a reduced holding coil consumption
AF.Z contactor relay withstand short dips and voltage interruptions (SEMI F47 compliance)
AF contactor relay have built in surge protection and does not require any additional surge suppressors.
The contactor relays have mechanically-linked contact elements compliant with Annex L of IEC 609947-5-1 and include the "mechanically Linked" symbol on their side
