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

NIST Calibrated 4 Gas Monitor USA
Features: PROFESSIONAL: A top quality 4 gas monitor with a built-in pump to detect Oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), and combustibles (LEL). Comes FACTORY-CALIBRATED. COLOR DISPLAY & PUMP: Color screen and graph functions allow for easy and intuitive operation. Built-in pump for super fast detection. RECORDED ALARMS: The detector records alarm events with date and time stamps. Stores 1,200 alarm records.STRONG: Robust design, constructed with high-strength ABS and anti-slip grip rubber. Water-resistant, dust-proof, and explosion-proof exceeding Exib IIB T4 Gb. TRUSTWORTHY: Arrives with calibration and QA certificates ** Product tested and verified in the USA ** Details: This is our best industrial 4 gas multigas detector. The 4 gas monitor has a built-in pump that allows for super quick sensor response and point or continuous sampling to confirm air quality, toxicity, and safety when entering confined spaces. A very robust unit for personal protection is used for workplace safety. This 4 gas monitor detects CO, H2S, O2, and LEL. It comes with a 32-bit microprocessor, color LCD, and graphing capabilities. Used in the industry by construction workers, utility workers, refinery workers, firefighters, maintenance engineers, inspectors, and those who spend time in sewers and waterworks, underground storage tanks, oil rigs, tanks, and silos, and often used in the maritime industry. The stainless steel probe is also popular, easy retracts down to one foot or extends to 4ft to sample gas at those hard-to-reach locations. For those that do not require a 4 gas meter without a built-in pump, we recommend our 4 gas meter FD-4A. If data logging is required our FD-4S multigas detector is an excellent option. Included: The product comes with the multi-gas detector, English manual, USB charging cable, charger, 4-foot telescopic stainless probe and tubing, and a USA NIST calibration certificate.
