THERMAL OVERLOAD RELAYS TM and TRMApplication, standards and installationThermal overload relays TRM are intended to protect low voltage motors and otherconsumers against nonpermissible overloads and phase-failure operation.Relays are in conformity with IEC 60947-4-1, EN 60947-4-1 and VDE 0660.They are normally intended for mounting on our contactors see ordering table.Individual screw mounting of the TM 40, TRM 12 and TRM 22 relays on plane surfaceor snap-on fastening to 35 mm mounting rail (according to DIN EN 50022) ispossible by using a special adaptor type ASM 40 and ASM 22.The relay TRM 400 is intended for individual screw mounting.2Current time curvesThe current time curves give correlation between the tripping time and the multiplifcatorof the present current I e. They are presented for a cold initial state of therelay. For relays warmed by 1,0 x Ie load, the tripping times are lower by 25%.The curve 2 is given for 3-phase operation. The curve 1 is given for 2-phase operation.For the protection of a 1-phase, or DC motor, serial conection of the maincircuit of relays is necessary. For that connection the tripping curve 2 is valid.2/4Technical dataRelay typeTM 40 TRM 12 TRM 22 TRM 75Insulation rating Ui V 690 1000 690Permissible ambient temperature oC - 25 to +55Degree of protectionReleasetimeclassifcationIP00class 10 (release time 4 s ... 10 sat 7,2 x Ie from cold state)Temperature compensation + + + + +Phase failure protection by differential phase shift + + + + +Test button + + + + +Reset button + + + + +Switch position indicator + + + + +Changeover to hand or automatic reseting + + + + +Vibration resistance g 8 8 8 8 8TRM 400Main circuitrated operational current (AC 50 to 400 Hz or DC) A 38 16 30 80 400conductor cross - sectionsolid or stranded mm 2 2,5 - 10 2,5 - 6 2,5 - 6 2,5 - 35 120/24fnely stranded with end sleeveScrew/Screw headTightening torquemm 2Nm1,5 - 6M4/PZ21.61,5 - 4M4/PZ21.21,5 - 4M4/PZ21.21,5 - 25M62.5M10Power input per polemax. at setting range min.
