Thermal Circuit Breaker 3120-F... Description The 3120 circuit breaker/switch combination is an ON/OFF switch with integral overcurrent protection (S-type TO CBE to EN/IEC 60934). The trip element is a bimetal. Type 3120 is ideally suited for overload protection of motors, pumps, transformers and cables. The 3120 circuit breaker is also available as a switch-only version in accordance with the IEC/EN 61058 (see data sheet switch 3120-F-..Q1). Product characteristics: l rocker or push button actuation l single pole and double pole versions l reliable switching behaviour (positively trip-free) l convenient snap-in mounting 1 l international approvals Options and add-on modules: l illumination l water splash protection Technical data l auxiliary contacts l under voltage trip For details please see Technical information l remote trip l magnetic trip Rated voltage AC 240 V, DC 50 V l push-in terminals Current rating range 0.1...20 A l appliance inlet module (up to 30A upon request for single pole units) Typical life 1-pole Typical applications AC 240 V: 0.1...20 A 30,000 operations at 1 x I , inductive N DC 50 V: 0.1...4 A 30,000 operations at 1 x I , inductive Medical and laboratory equipment, apparatus and machine N 4.5...16 A 30,000 operations at 1 x I , resistive construction, professional tools, household and garden appliances, N DC 28 V: 0.1...20 A 30,000 operations at 1 x I , inductive N offices machines, audio equipment, machine tools Typical life 2-pole Current ratings and internal resistance values AC 240 V: 0.1...16 A 50,000 operations at 1 x I , inductive N 17...20 A 30,000 operations at 1 x I , inductive N DC 50 V: 0.1...16 A 50,000 operations at 1 x I , inductive N Current rating Internal Current rating Internal 17...20 A 50,000 operations at 1 x I , inductive N (A) resistance (A) resistance Ambient temperature -30 60 C per pole () per pole () Insulation coordination 2.5 kV /2 reinforced insulation at 0.1 94 4 0.0435 (IEC 60664) operating area 0.2 24 4.5 0.0435 Dielectric strength 0.3 12 5 0.0325 Operating area test voltage AC 3,000 V pole to pole (2-pole) test voltage AC 1,500 V 0.4 5.30 6 0.0215 Insulation resistance > 100 M (DC 500 V) 0.5 4.20 7 0.0165 Interrupting capacity I 0.1...2 A 10 x I cn N 0.6 2.90 8 0.0165 2.5...20 A 1-pole 150 A 2-pole 250 A 0.8 1.50 10 < 0.02 Interrupting capacity (UL 1077) 1 0.9 12 < 0.02 I U I N N nc 1.2 0.80 14 < 0.02 1-pole, 2- pole 0.1...20 A AC 250 V 5000 A, C, 1 1.5 0.45 15 < 0.02 1-pole, 2- pole 0.1...20 A DC 50 V 1000 A, C, 1 2 0.27 16 < 0.02 Degree of protection operating area IP40 2.5 0.0785 18 < 0.02 (IEC 60529) terminal area IP00 with water splash cover IP54 or IP66 3 0.0595 20 < 0.02 Vibration 8 g (57-500 Hz), 0.61 mm (10-57 Hz) 3.5 0.0565 test to IEC 60068-2-6, test Fc 10 frequency cycles/axis Shock 30 g (11 ms) Current consumption of illumination test to IEC 60068-2-27, test Ea Corrosion 96 hours at 5 % salt mist, Operating voltage Current consumption test to IEC 60068-2-11, test Ka Y R G Humidity 240 hrs in 95 % RH DC 12 V 5.2 mA 2 mA 1.4 mA test to IEC 60068-2-78, test Cab DC 24 V 4.5 mA 2.2 mA 1.6 mA Mass approx. 33 g (2-pole) DC 48 V 4.5 mA 2 mA 1.6 mA approx. 27 g (1-pole) AC 115 V 2.8 mA 1.1 mA 1 mA approx. 42 g (2-pole with PT terminals) AC 230 V 2.2 mA 0.9 mA 0.9 mA 1806 www.e-t-a.de 1Thermal Circuit Breaker 3120-F...
