TMC Thermomagnetic Circuit Breaker Data Sheet 100695_01_en m CLIPLINE © PHOENIX CONTACT - 11/2006 co t [s] ne The enormous requirements where protective equipment is concerned, however, are more than fulfilled by the thermomagnetic circuit breaker. It has the following features: – Thermomagnetic triggering system – Modular and flexible structure – Auxiliary contacts for fault assessment – Fine nominal current gradations, which guarantee reliable protection of sensitive equipment and systems s. As system engineering becomes more automated, the demands as regards availability of technical equipment is increasing. Safety and protective equipment are particularly affected. The course of the thermomagnetic characteristic curve can be seen in the idealized characteristic curve below. With a delayed tripping mechanism, the thermal part of the characteristic curve protects against overload. High overload and short circuit currents cause the magnetic part of the circuit breaker to operate without delay and it is triggered within a matter of milliseconds. nt Description on l in ec om po 100 1 2 10 1 0,1 0,01 1 Figure 1 2 4 6 810 Idealized characteristic curve 1 Thermal triggering range 2 Magnetic triggering range .

The version with the normal blow tripping characteristic (M1) is equally suitable for applications with AC and with DC current. The fast-blow (F1) characteristic curve version is suitable for applications with DC current. If several circuit breakers are aligned in a row, take into account that they will heat up neighboring components. If several circuit breakers are loaded simultaneously, then the rise in the temperature caused by the components heating up each other is equivalent to a rise in the ambient temperature. In this case, only 80% of the nominal current can be supplied. Alternatively the load current can be increased by a multiplication factor and the circuit breaker can then be dimensioned accordingly: 10 1 20 1 Normal Blow (M1): Nominal Value 0.2 A ... 6 A Normal Blow (M1): Nominal Value 8 A ... 16 A – – – – + 23°C 100 DC AC 0,01 0,001 0,8 1 3 4 6 8 10 20 30 50 70 100 on l 2 0,01 0,001 0,8 1 DC – 30°C 1000 + 23°C 100 + 55°C 0,1 AC 0,01 2 3 4 6 8 10 20 30 50 70 100 Multiples of the nominal current Multiples of the nominal current lower tripping limit: 1.05 x IN upper tripping limit: 1.4 x IN 1 0,1 in ec 0,1 – – 10 1 1 60 1.24 Fast Blow (F1): Nominal Value 0.2 A ... 16 A (only for DC applications!) + 55°C om 10 nt + 23°C 100 + 50°C 10 – 30°C 1000 ne – 30°C 1000 50 0.16 10000 po Trip time in seconds Trip time in seconds lower tripping limit: 1.05 x IN upper tripping limit: 1.4 x IN 10000 10000 40 1.08 s. lower tripping limit: 1.05 x IN upper tripping limit: 1.4 x IN 30 1 m 0 0.92 co -10 0.84 Trip time in seconds Ambient Temperature [°C] Multiplication Factor 0,001 0,8 1 2 3 4 6 8 10 20 30 50 70 100 Multiples of the nominal current Dimensional Drawing 1 2 ,5 © PHOENIX CONTACT 11/2006 8 6 9 0 ,5 9 3 ,5 1 0 8 3 ,5 100695_01_en PHOENIX CONTACT GmbH & Co.
