Overload Relay Heater Tables

The Basics Of Selecting Overload Relays ECM

Types of relays.Overload relays and their heaters belong to one of three classes,depending on the time it takes for them to respond to an overload in the motor.The overload relay itself will have markings to indicate which class it belongs to.These include Class 10,20,and 30.The class number indicates the response time (in seconds).Technical Catalogue Thermal Overload Relays Electronic aM in conjunction with the thermal overload relay.The specifications in relation to short-circuit protection for contactors and overload relays must be noted when selecting the rating of fuses or circuit-breakers.Efficiency of protection device not effective partly effective fully effective SST 081 91 M 2 SST 081 91 M 1 SST 081 91 M 3Technical Catalogue Thermal Overload Relays Electronic aM in conjunction with the thermal overload relay.The specifications in relation to short-circuit protection for contactors and overload relays must be noted when selecting the rating of fuses or circuit-breakers.Efficiency of protection device not effective partly effective fully effective SST 081 91 M 2 SST 081 91 M 1 SST 081 91 M 3

Overload Relays Technical

in preparing the heater tables.Thermal Overload Heater Elements The heater element code number has a prefix letter which identifies the type of overload relay with which the heater is used and its tripping function.E and K type heater elements are applied to bimetal overload relays.The E type gives a standard trip (Class 20) and the KOverload Relays - EatonEaton offers a wide range of overload relays to provide full motor protection.The overload relay types include fixed bi-metallic,interchangeable heater bimetallic,and electronic.Flexible mounting ensures that they can be installed on a contactor,panel,or separate enclosure.Overload Relays - Contactors Overloads - Product GuidesAn overload relay is made up of a heater paired with normally-closed contacts that open once the heater gets too hot.The overload contacts are connected in series and located between the contactor and the motor itself to prevent the motor from restarting once the overload trips.

Overload Relays Thermal Unit Selection

overload relay has no power contacts and cannot disconnect the motor by itself.The control circuit contact must be wired in series with the coil of the contactor so that the contactor will de-energize when an overload occurs.Square D manufactures three types of overload relays,the melting alloy,the bimetallic,and solid state.Overload Relay Heater TablesOverload Relay Heater Tables Tables 298,299,391 Trip Amps Table 298 Table 299 Table 391 Size FLA Size FLA Size FLA 120,150 180 H,I J 270,360 R,K 650 Heater M Code 120,150 H,I 180 J 270,360 650 R,K M Heater Code 25,30 40 50,60 Heater Code 102 115 124 215 E24 242 E26 268 E27 307 E28 330 E29 110 123 136 215 242 268 307 330 E24 Overload Relay Heater Tables amp; ChartsGE Catalog Overload Relay Heater Table GE Catalog Overload Relay Heater Selection Guide GE Control Renewal Parts GE IEC Manual Motor Starters GE Industrial Circuit Breakers Thermal-Magnetic Trip GE Lighting Contactors GE Molded Case Circuit Breaker Quick Reference GE NEMA 300-Line Starters Technical Data GE NEMA CR306 CR386 Magnetic Starters
