Box Small 2P Ways Mini Breaker 2 Panel Sur Mounted Circuit
A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overload or short-circuit and under-voltage faults, they can automatically cut off the circuit. Its function is equivalent to a fuse switch. Combination with overheating and underheating relay, etc. Moreover, it is generally not necessary to change the components after breaking the fault current. It has been widely used. Power distribution is an extremely important link in the generation, transmission and use of electricity. The power distribution system includes transformers and various high and low voltage electrical equipment, and the low voltage circuit breaker is a widely used electrical appliance. The main contacts of the low-voltage circuit breaker are closed manually or electrically. After the main contact is closed, the free trip mechanism locks the main contact in the closed position. The coil of the overcurrent release and the thermal element of the thermal release are connected in series with the main circuit, and the coil of the undervoltage release is connected in parallel with the power supply. When the circuit is short-circuited or severely overloaded, the armature of the overcurrent release is pulled in to make the free release mechanism act, and the main contact disconnects the main circuit. When the circuit is overloaded, the thermal element of the thermal release will heat up and bend the bimetal, pushing the free release mechanism to act. When the circuit is undervoltage, the armature of the undervoltage release is released. Also actuate the free trip mechanism. The shunt release is used for remote control. During normal operation, its coil is powered off. When distance control is required, press the start button to energize the coil.Key FeaturesType：Mini

Set the operation time to the second (1-99 minutes). Select either the speed (0-4000 RPM) or centrifugal force (0-2100 XG). When the centrifuge machine is running you can easily see the time remaining and the current speed or force. The Fristaden Lab centrifuge's precise, independent controls are well suited for the lab, clinic or classroom. HIGH CAPACITY FOR THE KITCHEN OR LAB Enterprising chefs and bartenders now use lab centrifuges to separate juices and sauces to produce more concentrated colors and flavors. With a large max capacity of 300 milliliters (about 1 1/4 cups) and a powerful centrifugal force of 2100 XG, the culinary centrifuge is practical for fast-paced bars and kitchens. The instrument can be used for both cooking and research (food-safe tubes not included). KNOW YOUR RELATIVE CENTRIFUGAL FORCE Two centrifuges with the same speed (RPM) can have much different forces (and thus separation times) depending on their size. The lab centrifuge allows you to directly program and view relative centrifugal force (in 1XG increments) or speed (in 10RPM increments). Knowing the exact force used to separate your liquids saves time doing calculations and ensures more accurate, replicable data. ROBUST DESIGN, QUIET OPERATION The benchtop centrifuge is built with tough, lab quality materials to handle hard, everyday use, year after year. This includes a powerful 200W motor, LCD display and aluminum alloy rotor. The centrifuge stays firmly in place with suction cup feet. Even while operating at high speeds, the centrifuge machine operates quietly. The centrifuge can be setup in under 5 minutes and comes with a detailed, user-friendly instruction manual.Key FeaturesBrand: Fristaden LabSpeed (RPM): 0-4000Speed Increment: 10RPMRelative Centrifugal Force (XG): 2100Relative Centrifugal Force Increment: 1XGCentrifugal Radius (mm): 120Machine Power (W): 200Timer Range (minutes): 0-99Angle Rotor: 6 x 50ml Tubes

The coil of the overcurrent release and the thermal element of the thermal release are connected in series with the main circuit, and the coil of the undervoltage release is connected in parallel with the power supply. When the circuit is short-circuited or severely overloaded, the armature of the overcurrent release is pulled in to make the free release mechanism act, and the main contact disconnects the main circuit. When the circuit is overloaded, the thermal element of the thermal release will heat up and bend the bimetal, pushing the free release mechanism to act.
