Overload Or Thermal Protection Ansi 49
Class 5, 10, & 30 overload relays will trip within 5, 10, & 30 seconds respectively at 600% of motor full load amps Class 5 is usually used for motors requiring extremely fast tripping Class 10 is commonly used to protect artificially cooled motors such as submersible pump motors of low thermal capacityFigure 5 (below) shows a B Trip Curve overlaid onto the chart The three major components of the Trip Curve are 1 Thermal Trip Curve This is the trip curve for the bimetallic strip, which is designed for slower overcurrents to allow for in rush/startup, as described above 2 Magnetic Trip Curve This is the trip curve for the coil or solenoid
Class 10 overload curve siemens
Class 10 overload curve siemens-Ples of overload relay trip current NEMA has classified overload relays in three classes 1 NEMA Class 10 for protecting submersible pump motors, hermetically sealed refrigeration motors, etc, trips in less than 10 seconds at 6 times trip current 2 NEMA Class for protecting standard motors trips in less than seconds at 6 times trip current 3 NEMA Class 30 trips in less thanIEC tripping time curves as a function of actual to fullload or setting current ratio, for classes 10, , and 30, and typical motor damage curves for 30min and 60min thermal time

RMSO Class 10 Bimetallic Overload Relay (69A) for RC9A, RC12A, RC18A, RC22A, RC32A, and RC40A Contactors Extended Part No RMSO3275A Benshaw RMSO/SPO Series Overload Relays are bimetallicstyle relays designed to protect AC3 circuits and motors against overloads, phase failure, long starting times and stalling of the motorThe most common classes are 5, 10, & 30 Class 5, 10, & 30 overload relays will trip within 5, 10, & 30 seconds respectively at 600% of motor full load amps A Class 10 overload relay, for example, has to trip the motor offline in 10 seconds or less at 600% of the full load amps (which is usually sufficient time for the motor to reach full speed)OE = Electronic overload relay Mounting Blank = Direct to contactor S = Separate mount (Frames C and G only) Trip Type CS = Selectable Class 10A, 10, , 30 GS = Ground fault with selectable Class 10, Overload Release Contactor Frame 1P6 = 033–165A 005 = 1–5A 0 = 4–A B = 45 mm 1P6 = 033–165A 005 = 1–5A 0 = 4–A 045 = 9
Tripping classes of the thermal overload relays Standard classes in IEC are classes 10 A, 10, , 30 The tripping class indicates according to IEC the maximum tripping time in seconds under specified conditions of test at 72 times the setting current and specifies tripping and non tripping times for 15 and 72 times theC440 Hot Trip Curves 10A, 10, , 30 Auslösekennlinie, C440 1&3phasig Tripping characteristics, 1&3phase C440 Courbe de déclenchement, C440 monophasé et trois Caratteristica di intervento, C440 1&3 polare Curva de disparo, C440 1&3 polos 1000 1 10 100 01 1 2 3 456 7 10 Class 10A Class 10 Class Class 30 t A X I e Class t A (s6 (b) Electric power and lighting circuits (1) Routine opening and closing of circuits Load rated switches, circuit breakers, or other devices specifically designed as disconnecting means shall be used for the opening, reversing, or closing of circuits under load conditions Cable connectors not of the load break type, fuses, terminal lugs, and

It is commonly classified into Class 10, Class , Class 30 and Class 5 The OLR trips in 10 seconds, seconds, 30 seconds and 5 seconds respectively at 600% of full load current to the motor Class 10 and Class are very commonly used ones Class 30 overload relays are used for protection of motors driving high inertia loads and Class 5 relays are used for the motors requiring very fastTripping curve Ir Pickup Setting Value The overload or thermal protection pickup (Ir) is set by using a multiposition dial The default Ir pickup setting value is 04 x In (minimum dial value) The overload or thermal protection tripping range is 105–1 x Ir according to IEC/EN
