Miniature circuit breakers are available in the following ratings: 6A, 10A, 16A, 20A, 25A, 32A, 45A, 50A, 63A, 80A, 100A, 125A. Rated voltage of the operating equipment/ circuit to be protected should also be taken into account while selecting an MCB. These circuit breakers are suitable for use with 60C or 75C conductors. It is widely used in building power distribution, industrial power distribution, as well as control and protection for a variety of equipment with operating current not exceeding 125A. All miniature circuit breaker working wholesalers & miniature circuit breaker working manufacturers come from members. Combining the 5SY MCB with the 5SM6 arc-fault detection unit (AFDD) further expands the range of functions. The double pole MCB has two switches and also protects two-phase and neutral. For example, large battery systems, motors, transformers, etc. Miniature circuit breaker in CHINT provide the overload protection, short circuit protection and isolation. The two main types of miniature circuit breakers are thermal-magnetic and thermal-magnetic release (TMR). Same breaker size for entire rating range. R. STAHL uses cookies to offer you the best possible service on our website. Circuit Breaker Type Standard; Number of Poles 3; DC Voltage Rating Not Rated; Circuit Breaker Actuator Toggle; Circuit Breaker Mounting Style Bolt On; Phase Three; Series BQ; Max. See the Supplemental Digest, Section 3 for 3 corner grounded systems. Thermal or thermal-magnetic operation. By closing the window you will acknowledge our cookie policy. MCB trip curve decides the type of MCB that has to be used for different types of appliances or devices. The specially developed arc c Thermal magnetic breakers use a bimetallic strip that heats up when current flows through it. What are the three types of miniature circuit breakers? For example, large battery systems, motors, transformers, etc. 4. Triple Pole MCB. Made-in-China.com helps global buyers match their buying requests with the right supplier efficiently. 3. The QO 35200 A and all QO-PL and QOT tandem circuit breakers have box-type lugs suitable for single-wire terminations. A miniature circuit breaker is an automatic switch that protects an electrical circuit from overcurrents or power surge. It is a protective device that trips when there is a fault current on a circuit. The heating causes the strip to expand and trip a mechanism that opens the circuit. An MCB is an automatically operated electrical switch. Thermal or thermal-magnetic operation. Circuit breakers and fuses are used to protect against overloads and short circuits in conductors for all types of applications. MCCB has a These BQ and BQH series miniature circuit breakers are bolted into place in panelboards, so they're more stable than plug-in breakers. Single Pole MCB.
