TXB7S-63 IC Card Prepaid Electric Meter Circuit Breaker

TXB7S-63 with shunt trip circuit breaker——IC card prepaid electricity meterminiature circuit breaker(also known as electric meter cost control circuit breaker), with intelligent shunt tripping function, suitable for remote control disconnection or automatic signal control disconnection of lines with AC 50Hz (or 60Hz), rated working voltage of 230/400V, and rated current of 63A. It also serves as overload and short circuit protection for the line and can be used for infrequent operation conversion of the line. At present, it is widely used in conjunction with IC card prepaid electricity meters to control the on/off of power lines.
Circuit breakerCompliant with IEC60898, GB10963, GB14048.2 standards and possessing international advanced level.

TXB7S-63 with shunt trip circuit breaker (IC card prepaid meter dedicated circuit breaker)TXB7N miniature circuit breakerAssembled with intelligent module shunt release. There are two ways to release: instantaneous release and delayed release.
The shell is made of flame-retardant, arc resistant, high-strength new plastic, which has good impact resistance and flame retardancy.
The contact system adopts an electric repulsion mechanism, greatly improving the breaking capacity of the circuit breaker and making its function more complete and reliable. The L pole has electromagnetic and thermal protection functions, the N pole has electromagnetic protection function, and the S pole has shunt tripping function.
The fully automatic winding shunt release coil undergoes a 3300V (1.2/50 μ s) voltage test and meets the insulation level III of CEI28-6.
The life of the shunt release exceeds 4000 times.
The shunt trip coil has a current limiting effect, ensuring that the current absorbed by the coil in the shunt trip circuit is within a reliable safety value, which can effectively prevent coil burnout during actual use.
The shunt release device is designed as a single pole with strong anti-interference ability, which can effectively prevent the misoperation of the shunt release under electromagnetic interference and thermal interference.
Prepaid electric meter circuit breaker is designed specifically for use with single-phase and three-phase four wire IC card energy meters. It has anti time overload protection and short circuit protection functions, and can receive signals from IC card energy meters to cut off the circuit, preventing users from delaying electricity bills. It has been widely used in the national power grid one household one meter renovation project.

TXB7S-63 with shunt trip circuit breaker (electric meter cost control circuit breaker) with delayed shunt trip action characteristics. The working voltage of the circuit breaker is any value within the range of 70% to 110%. When in use, a control voltage, i.e. signal voltage (which can be provided by a remote control circuit or IC card electricity meter), is applied to the terminals of the circuit breaker and intelligent shunt trip breaker through a signal line, and then the circuit breaker handle is pushed to the closed position for closing. When remote control is required (or when the IC card meter is overdue), the control voltage can be disconnected through the control system. The circuit breaker should be able to reliably disconnect within 0.5s ≤ t ≤ 2s, and also have short-circuit and overload functions.
