TMC Thermomagnetic circuit breaker for mounting on a DIN rail Data sheet 100695_en_03 1 © PHOENIX CONTACT 2012-03-09 Description t [s] Single or multi-position thermomagnetic circuit breaker with lever actuation, DIN rail mounting, trip-free mechanism that cannot be influenced, various characteristic curves, all-pole tripping. The circuit breakers meet the requirements of circuit breaker standard EN 60934 (IEC 60934): S-type, TM. Typical areas of application are telecommunications systems, power supply units, industrial switchgear and control systems, and rail vehicles. The ideal characteristic curve shown here illustrates the curve of the thermomagnetic trigger characteristic. The timedelayed tripping protects the thermal part of the characteristic curve against overload. The magnetic part of the circuit breaker responds without delay to high overload and short-circuit currents and trips within a few milliseconds. 100 ① ② 10 1 0,1 0,01 1 2 4 6 810 20 Multiples of the nominal current Figure 1 Ideal characteristic curve ① Thermal tripping range ② Magnetic tripping range Make sure you always use the latest documentation.

The version with the "medium-blow (M1)" trigger characteristic is suitable for AC and DC applications. The "fast-blow (F1)" characteristic version is suitable for DC applications. The characteristic curves (see page 7) depend on the ambient temperatures. To avoid early or late disconnection, the circuit breaker nominal current must be multiplied by a factor. Ambient temperature -30°C -20°C -10°C 0°C 10°C 20°C 30°C 40°C 50°C 60°C Multiplication factor 0.76 0.79 0.83 0.88 0.93 1 1.04 1.11 1.19 1.29 The characteristic curves (see page 7) are also valid for multi-position devices if all positions have an equal load. For multi-position devices and only 1-pos. overload, the thermal tripping limit changes for characteristic curves F1 and M1 to a maximum of 1.7 x IN. For DC, the magnetic operate values of the curves are around factor 1.3 higher. Tripping is supported even with high-energy current peaks < 0.003 s. NOTE: When mounting several circuit breakers in rows, observe the mutual warming effect. When the circuit breakers are loaded simultaneously, a mutual warming effect occurs, which has the same effect as an increase in ambient temperature. In this case, the nominal current can only be led to 80%. Alternatively, the load current can be increased by a multiplication factor and the circuit breaker dimensioned accordingly. 100695_en_03 PHOENIX CONTACT 6 TMC 5.1 Lower tripping limit: 1.05 x IN Upper tripping limit: 1.4 x IN Switching time in seconds 10000 – 30°C 1000 + 23°C 100 10000 1000 100 – 30°C + 23°C + 55°C + 50°C 1 1 0,1 DC 0,1 0,01 AC 0,01 0,001 0,8 1 0,001 0,8 1 – – Lower tripping limit: 1.05 x IN 10 10 5.2 – Switching time in seconds – – Medium-blow (M1): Nominal value 0.2 A ... 6 A Multiples of the 2 3 4 6 8 10 20 30 50 70 100 nominal current Multiples of the 2 3 4 6 8 10 20 30 50 70 100 nominal current Medium-blow (M1): Nominal value 8 A ... 16 A Lower tripping limit: 1.05 x IN Upper tripping limit: 1.4 x IN Switching time in seconds 10000 – 30°C 1000 + 23°C 100 + 55°C 10 1 DC 0,1 AC 0,01 0,001 0,8 1 5.3 Multiples of the 2 3 4 6 8 10 20 30 50 70 100 nominal current Fast-blow (F1): Nominal value 0.2 A ... 16 A Only for DC applications. 100695_en_03 PHOENIX CONTACT GmbH & Co.
