This selection guide will help you choose the best relay for your application with easy access to additional online Moulded Case Circuit Breaker and Thermal Overload Relay functions integrated into a highly compact unit known as Motor Protection Circuit Breaker. Thermal Overload Relay setting = 120%x12.28 = 14.7A. TeSys D dimensions: TeSys™ D Contactors, AC and DC Coil to TeSys™ D Thermal Overload Relay Dimensions Footnotes Complete the catalog number by adding the coil voltage code from TeSys D Coil Voltage Codes for example, LC1D09 G7 ). Select overload relay by full load amp current range. a Overload Relay Selection Multi-Speed Each speed requires a separate set of overloads. To Select Heater Catalog Number Use b Product Class b Controller Size b Motor Amp b Phase 1. Full load current range refers to a range of current values for a relay to be set to. Relays are protected against phase loss and phase imbalance. Overload Relay ESP200 starters do not require heater elements. CEP7-EE is a full-featured, selectable trip class (10, 15, 20 & 30) 3-phase application overload relay with provision for field-mountable modules to handle remote reset, ground fault and other functions previously available only in higher priced electronic overload relays. Under the effect of the heating, the bimetals bend, cause the relay to trip and the position of the auxiliary contacts to change. Relays are protected against phase loss and phase imbalance. Manufacturer: Schneider Electric: Description: TeSys K Differential thermal overload relays Class 10A by screw clamp terminals on downstream, relay setting range : 1,2…1,8 The trip function also includes a trip delay time with a range of 0.1…25.0 seconds. Selection of thermal overload. Manual/Auto reset selection This new ABB product family is a communication device range with switching and automation components which can be combined easily with standard fieldbus systems. They offer reliable protection for motors in the event of overload or phase failure. Selection tables ... aM in conjunction with the thermal overload relay. • Panel mounts using a metal adapter plate. 2012 7 Overview Available — Not available 1) Motor currents up to 820 A can be recorded and evaluated by a current measuring module, e.g. Buy LRD3322 - Schneider Electric - Electronic Overload Controller, TeSys D IEC, 17 A, 25 A.

Tweet. Unclips without the use of a tool. A Class 30 overload relay will trip in 30 seconds or less at a current equal to 600 percent of its rating. Electric Motor Proper Contactor And Overload Selection Tables. a Overload Relay Selection Multi-Speed Each speed requires a separate set of overloads. In order for the thermal overload relay to trip, the relay's full load current point must be set to match the value on the rating plate. If the motor is connected in star = 440 V 60 Hz the overload relay then has to be set to 3.1 A. 1.15, the set current for the overload relay can be raised by 15% compared to full-load current or to the service factor amps (SFA) which is normally indicated on the nameplate. Siemens Siemens Overload Relay Heater Table Siemens Electrically Held Contactors, Class LE ... Sprecher + Schuh Motor Current Rating Chart. Thermal Overload Relay setting = 120%x Full Load Current(Phase) Max. For example, let’s look at an electronic overload relay: The relay’s CT input impedance or burden (Z­B) = 0.01Ω The maximum current (I) = 10 A The CT rating (P) = 5VA Thermal Overload Relay setting = 70%x Full Load Current(Phase) Min.
