Schneider breaker EA9RNL leakage protection circuit breaker Schneider Electric is one of the world's top 500 enterprises, is the world's power and industrial control specialists. Business throughout the residential, building, industry and energy and infrastructure markets four, as one of its three brands of Merlin Gerin switch socket panel of the whole process is controlled by the Schneider Electric global harmonization of product quality management and monitoring system, a high-quality reputation is so MGE products have fully guaranteed. Schneider brand recognize care of your electrical safety a circuit breaker (air switch) knowledge Introduction breakers, also known as air switch, also known as automatic switches, low voltage circuit breakers. The principle is: when the operating current exceeds the rated current, short-circuit, loss of pressure, etc., automatically cut off the circuit. Currently, the total household switch common with knife switch with porcelain insert Insurance (which has been eliminated) or air switch (with leakage protection MCB). Currently DZ series home use air switch, a common model / specification: C16, C25, C32, C40, C60, C80, C100, C120, and other specifications, where C represents the tripping current, namely the current take-off, such as C32 represents takeoff current of 32A, 6500W heater is usually installed to use the C32, installation 7500W, 8500W heater C40 use of open space, state: because many models breaker, breaker We used the pictures are of the same type, the specific kind to baby Title Description prevail, pro, please rest assured purchase! Second, the product description ◆ Manufacturer: Tianjin Merlin Gerin (Schneider Electric) ◆ Series: EA9 = Easy9 series ◆ Product categories: C = "phase + neutral" earth leakage circuit breaker (integration); ◆ Breaking Capacity: 4 = 4500A ◆ Poles: 5 = Ph + N (width 18mm) ◆ tripping curve (C): to protect normal load and distribution cable ◆ Rated current: 10A 16A 20A 25A 32A 40A ◆ rated residual operating current : 30mA Third, the basic parameters ◆ standard: GB10963 / IEC60898; ◆ Tripping characteristic: C ◆ Mechanical life: 20,000 times ◆ obtain CCC certification Sales Tel: 15157772419 Online QQ: 3229842726 Fourth, the main advantages of the circuit breaker for the terminal EA9A45 line overload and short circuit protection, it can cut off the phase and neutral, but neutral does not provide protection. Fifth, the explanation points EA9A45 and EA9A47 performance parameters are different, and different occasions. 1. The current rating is different. EA9A45 maximum rated current is only 32A, while EA9A47 currently rated current up to 40A; various 2. connection capacity. EA9A45 applies only 10mm2 and below the wire, and EA9A47 maximum wiring can reach 35mm2; 3. different widths. EA9A45 width of 18mm, and EA9A47 width of 36mm. It is because of the different parameters of the above, the decision to use two different occasions. EA9A45 generally used for the sub-loop and EA9A47 more suitable for household distribution box into the line overall. Sixth, select the circuit breaker (air switch) ampere calculations a = 735W≈750W 1.5 匹 = 1.5 × 750W = 1125W 2 匹 = 2 × 750W = 1500W 2.5 匹 = 2.5 × 750W = 1875W This calculation method and so on. (1) Example: 3 A number of the air conditioner should switch (220V voltage) to select 750W × 3 匹 = 2250W × 3 times (rush current) = 6750W ÷ 220V = 30.68A≈32A. (2) Example 5 A number of air-conditioned switch (380V voltage) 750W × 5 匹 = should select 3750W × 3 times (rush current) = 1125W ÷ 380V = 29.60≈32A (power ÷ Voltage = amps) Note: air switch at rated load average operating life of 20,000 times. In understanding the GFCI, air switch principle, function of the general situation in the optional distribution box for customers in the process, should be based on lighting small, socket, air conditioning, large matching principle. For flexible distribution solutions according to customer requirements and decoration personality differences, combined with the actual situation. There are numerous species distribution, the following configuration options on five common characteristics, installation considerations for your reference. Seven, illustrate points 1. micro leak electrical leakage annex action time, there is no sense of delay, but the action is a process, and this process will take some time, IEC10091 in 5.3.8 and GB16917.1 in 5.3.8 regulations for this are clearly defined, requiring maximum operating time of less than 0.3 seconds, this product basically can do 0.06 seconds; 2. GFCI only leakage protection, earth leakage circuit breaker and short-circuit protection, overload protection and leakage protection; 3. The use of bar code management system, reliable bar code and security labels double insurance system, dual recognition, dual protection. Eight breaker (air switch) polarity and representation unipolar 220V 220V bipolar cutting FireWire FireWire and the zero line and cut off three 380V three-phase 380V three-phase line to shut off all four firing a phase zero line all cut off. Nine, the purchase of electricity should install modern home lighting circuits, power outlet circuits, air-conditioning circuit, separate the wiring, when one of the circuit (such as jack circuit) fails, the other can still supply circuit is normal. Outlet circuit leakage protection device should be installed to prevent leakage caused by household appliances, personal electric shock. 1, total household distribution box switch generally choose bipolar 32-63A miniature circuit breaker or disconnecting switch. 2, the lighting circuit is generally small circuit breaker 10-16A. 3, outlet circuit usually selected 16-20A leakage protection circuit breaker. 4, air-conditioning circuit generally choose 16-25A miniature circuit breakers. 5, the use of bipolar or 1P + N (phase + neutral) breaker, when the line short-circuit or leakage fault, immediately cut off the power supply line and the neutral line to ensure personal safety and the safety of electrical equipment. Choose above for reference only, actual household electrical power is not the same, according to the specific choice of design electrician prevail. Merlin (Merlin Gerin) with her high-quality power distribution products and switchgears known, building set her leadership in the international market. Around the world, Merlin Gerin brand of high, medium and low voltage equipment provided with uninterrupted power supply, monitoring and protection of electrical devices to ensure the safety of personnel and equipment.
