Leakage circuit breaker RMM2L model purpose and wiring diagram Use of leakage circuit breaker RMM2L The plastic case circuit breaker with residual current protection is a derivative product of the RMM2 series. Its structure is based on the original RC type residual current release. Therefore, the okplazas.com leakage circuit breaker has the same RMM2 The same technical characteristics of the model circuit breaker, and the corresponding accessories can also be used together.

Molded case circuit breaker RMM2 model parameters and accessories Application range of RMM2 molded case circuit breaker The rated insulation voltage of this series of plastic case circuit breakers is 800V, which is mainly suitable for distribution networks with AC50HZ, rated working voltage of 400V, and rated current of 630A and below.okplazas.com molded case circuit breaker RMM2 can be used as a power distribution and protection circuit device, which can effectively prevent the power equipment from being damaged and affected by overload, undervoltage, short circuit and other faults

The difference between fast fuse and ordinary fuse The structure difference between fast fuse and ordinary fuse 1. Ordinary fuse links are made of metal wires with certain geometric shapes. 2.The fuse of the fast fuse not only has a certain formed metal wire, but also has a solder joint of a certain material on the metal wire. The purpose of this is to make the fuse of the fast fuse occur in the circuit. It can reliably perform rapid disconnection under overload conditions.

Principle characteristics and reasonable selection of high-voltage current-limiting fuses Principle of High Voltage Current Limiting Fuse First of all, this component has the two major characteristics of current limiting and rapidity. After the protected line fails, the highest current peak is usually in the first half wave, so when the shell is broken, all short-circuit currents are equal. Can be transferred to high-voltage current-limiting fuse.

ABB Molded Case Circuit Breaker Tmax XT Series Brochure Overview of ABB Molded Case Circuit Breaker Tmax XT Series Mainly can be divided into 4 types, including XT1, XT2, XT3, XT4, the frame current can reach up to 250A, and the number of poles of ABB molded case circuit breaker Tmax XT series can be divided into 3 poles and 4 poles, if it is based on the installation method It can be divided into fixed type, plug-in type and withdrawable type.

220V AC contactor wiring method and physical wiring diagram Brief introduction of contactor If the contactor is divided only from the voltage, there are two types of AC contactor and DC contactor. If it is divided from the function, purpose, and top, the contactor has vacuum, switching capacitor and other types. And AC contactors are widely used in electric power, power distribution or power-using places.

380V AC contactor installation physical wiring diagram Wiring diagram of 380V AC contactor In fact, the power side of the AC contactor is mainly connected to the three-phase power supply when wiring. Generally, the contactor shell is marked with 1L1, 3L2, 5L3, or directly L1, L2, L3. . So just remember that this is connected to the power supply, and the other load side of the AC contactor needs to be connected to the load. It is also marked on the shell, usually 2T1, 4T2, 6T3, or directly T1, T2 、T3 is like this, please see the actual picture below for the specific situation.

Siemens soft starter 3RW51 model parameters and troubleshooting methods Overview of Siemens soft starter 3RW51 It can be said that this equipment is developed and manufactured on the basis of Siemens' deep experience in soft start applications. The 3RW51 soft starter can be used for loads that need to control the start and stop of fans, conveyor belts, compressors and pumps. Installation and use on occasions.

Thermal overload relay wiring diagram and reset adjustment instructions Thermal overload relay wiring diagram First of all, the main structure of the thermal overload relay is composed of two parts, including the thermal element and the output auxiliary contact. According to the wiring diagram below, we can clearly see that the terminal on the left is the terminal for the relay in the main circuit, which is divided into 3 channels and a total of 6 points, and the terminal on the right is the output auxiliary contact terminal.

The function and working principle of thermal overload relay The role of thermal overload relay Thermal overload relays mainly generate heat through the current flowing into the thermal element, and promote the shape change of the bimetallic strips with different expansion coefficients.
