The trip element is a bimetal. Type 3120 is ideally suited for overload protection of motors, pumps, transformers and cables. 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 l international approvals Options and add-on modules: l illumination l water splash protection l auxiliary contacts l under voltage trip l remote trip l magnetic trip (see thermal-magnetic circuit breakers) l push-in terminals l appliance inlet module Medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, offices machines, audio equipment, machine tools Current ratings and internal resistance values Current consumption of illumination Current rating (A) Internal resistance per pole (Ω) Current rating (A) Internal resistance per pole (Ω) 0.1 94 4 0.0435 0.2 24 4.5 0.0435 0.3 12 5 0.0325 0.4 5.30 6 0.0215 0.5 4.20 7 0.0165 0.6 2.90 8 0.0165 0.8 1.50 10 < 0.02 1 0.9 12 < 0.02 1.2 0.80 14 < 0.02 1.5 0.45 15 < 0.02 2 0.27 16 < 0.02 2.5 0.0785 18 < 0.02 3 0.0595 20 < 0.02 3.5 0.0565 Operating voltage Current consumption Y R G DC 12 V 5.2 mA 2 mA 1.4 mA DC 24 V 4.5 mA 2.2 mA 1.6 mA DC 48 V 4.5 mA 2 mA 1.6 mA AC 115 V 2.8 mA 1.1 mA 1 mA AC 230 V 2.2 mA 0.9 mA 0.9 mA For details please see Technical information Rated voltage AC 240 V, DC 50 V Current rating range 0.1...20 A (up to 30A upon request for single pole units) Typical life 1-pole AC 240 V: 0.1...20 A 30,000 operations at 1 x IN, inductive DC 50 V: 0.1...4 A 30,000 operations at 1 x IN, inductive 4.5...16 A 30,000 operations at 1 x IN, resistive DC 28 V: 0.1...20 A 30,000 operations at 1 x IN, inductive Typical life 2-pole AC 240 V: 0.1...16 A 50,000 operations at 1 x IN, inductive 17...20 A 30,000 operations at 1 x IN, inductive DC 50 V: 0.1...16 A 50,000 operations at 1 x IN, inductive 17...20 A 50,000 operations at 1 x IN, inductive Ambient temperature -30 … 60 °C Insulation coordination (IEC 60664) 2.5 kV /2 reinforced insulation at operating area Dielectric strength Operating area pole to pole (2-pole) test voltage AC 3,000 V test voltage AC 1,500 V Insulation resistance > 100 MΩ (DC 500 V) Interrupting capacity Icn 0.1...2 A 10 x IN 2.5...20 A 1-pole 150 A 2-pole 250 A Interrupting capacity (UL 1077) IN UN Inc 1-pole, 2- pole 0.1...20 A AC 250 V 5000 A, C, 1 1-pole, 2- pole 0.1...20 A DC 50 V 1000 A, C, 1 Degree of protection (IEC 60529) operating area IP40 terminal area IP00 with water splash cover IP54 or IP66 Vibration 8 g (57-500 Hz), ± 0.61 mm (10-57 Hz) test to IEC 60068-2-6, test Fc 10 frequency cycles/axis Shock 30 g (11 ms) test to IEC 60068-2-27, test Ea Corrosion 96 hours at 5 % salt mist, test to IEC 60068-2-11, test Ka Humidity 240 hrs in 95 % RH test to IEC 60068-2-78, test Cab Mass approx. 33 g (2-pole) approx. 27 g (1-pole) approx. 42 g (2-pole with PT terminals) |
