Prepaid meters as intelligent terminal of intelligent grid, is gradually into our lives. The existing meter dedicated circuit breakers, can only achieve automatic power-off after arrears, need manual transmission after payment, for this, the power grid company has invested a huge manpower cost for maintenance work, but still can not solve the problems of timeliness of charging, greatly reducing the customer's electricity experience.
TXB7S5-63 Miniature Circuit Breaker, is a new meter dedicated MCB switch with automatic recovery circuit researched and developed independently by TAIXI, not only achieve automatic power-off after arrears, automatic power-on after payment, but also to achieve the effective protection of the line and terminal equipment, meanwhile feedback the state signal of closing and opening.
TXB7S5-63 automatic Circuit Breaker (MCB switch) meets standards of SGCC "Technical specification of watt-hour meter with external load switch" and IEC60898, GB10963, GB14048.2, reaches the international advanced technology level.

»Compact size: single phase 1P+N (2P), width 72mm; three-phase four-wire 3P+N (4P), width 108mm
»Quick action: matching miniature circuit breakers, quick action, response time <0.1s
»Good synchronization: the integrated design of mechanism and circuit breaker, through opening-closing of the built-in relay device to make and break circuit
»Powerful function: with functions of automatic switch, tripping self-keeping after arrears
»Stable and reliable: mechanical life up to 10,000 times
»Ultra-low power consumption: operating mechanism power consumption ≤ 0.05W
»Case material: all use flame-retardant case material, the internal use copper fittings
»Adaptable: suitable for environment of -25℃~70℃
»Optional functions: leakage protection
