Thermal Overcurrent Circuit Breaker 1140-... Thermal Overcurrent Circuit Breaker 1140-... (2-pole) Description Miniaturised double pole thermal circuit breaker with push-to-reset tease-free, trip-free, snap action mechanism (R-type TO CBE to EN 60934). Threadneck panel mounting. Suitable for line and neutral switching - the thermal actuator operating on one pole simultaneously opens both poles under overload conditions. Approved to CBE standard EN 60934 (IEC 60934). Typical applications Motors, transformers, solenoids, hand-held machines and appliances. Especially suited to AC duties where the correct orientation of line/ 1 neutral is not known/cannot be guaranteed. 1140-G15 Ordering information Technical data Type No. 1140 double pole threadneck panel mounting For further details please see chapter: Technical Information Mounting Voltage rating AC 240 V DC 48 V G1 threadneck panel mounting 3/8-27UNS, with hex nut and (UL: AC 250 V DC 50 V) knurled nut (hardware bulk shipped with 5 pcs plus) Number of poles Current ratings 0.05...16 A 5 double pole, 1-pole protected Typical life Actuator style AC + DC 0.05...3 A 300 operations at 2 x I , inductive N 1 black push button 3.5...8 A 200 operations at 2 x I , inductive N Terminal design 9...16 A 100 operations at 2 x I , inductive N P7 blade terminals DIN 46244-C (QC 2x.110) Ambient temperature -20...+60 C (-4...+140 F) T 60 Characteristic curve Insulation co-ordination rated impulse pollution M1 medium delay (IEC 60664 and 606664 A) withstand voltage degree Current ratings 2.5 kV 2 0,05...16 A reinforced insulation in operating area 1140 - G1 5 1 - P7 M1 - 16 A ordering example Dielectric strength (IEC 60664 and 60664A) test voltage operating area AC 3,000 V pole/pole AC 1,500 V Preferred types Insulation resistance > 100 M (DC 500 V) Interrupting capacity I 0.05...3 A 6 x I Preferred types Standard current ratings (A) cn N 3.5...8 A 8 x I N 0.5 1 1.5 2 3 4 5 6 8 10 12 15 9...16 A 120 A Interrupting capacity I U x x x x x x x x x x x x 1140-G151-P7M1 N N (UL 1077) 0.05...16 A DC 50 V 2,000 A 0.05...16 A AC 250 V 2,000 A Degree of protection operating area IP40 Standard current ratings and typical internal resistance values (IEC 60529/DIN 40 050) terminal area IP00 Vibration 10 g (57-500 Hz) 0.76 mm (10-57 Hz), Current Internal Current Internal to IEC 60068-2-6, test Fc, rating (A) resistance () rating (A) resistance () 10 frequency cycles/axis Shock 25 g (11 ms) 0.05 345 1.8 0.3 to IEC 60068-2-27, test Ea 0.06 240 2 0.3 Corrosion 96 hours at 5 % salt mist, to IEC 60068-2-11, test Ka 0.08 142 2.5 0.2 Humidity 240 hours at 95 % RH 0.1 88 3 0.1 to IEC 60068-2-78, test Cab 0.2 24 3.5 0.08 Mass approx. 13 g 0.3 9.9 4 0.07 0.4 5.9 5 0.05 Approvals 0.5 3.7 6 0.04 Authority Standard Voltage ratings Current ratings 0.6 2.2 7 < 0.02 VDE IEC/EN 60934 AC 240 V 0.05 A16 A 0.7 1.9 8 < 0.02 DC 48 V 0.05 A16 A 0.8 1.4 10 < 0.02 UL UL 1077 AC 250 V 0.05 A16 A DC 50 V 1 0.9 12 < 0.02 0.05 A16 A 1.2 0.6 15 < 0.02 CSA C22.2 No 235 AC 250 V 0.05 A16 A DC 50 V 0.05 A16 A 1.5 0.5 16 < 0.02 1635 www.e-t-a.de 3Thermal Overcurrent Circuit Breaker 1140-...
