YDMS-63   IC pre-paid card control circuit breaker , with intelligent shunt trip function for AC 50Hz (or 60Hz), rated working voltage of 230/400V, rated current of 63A circuit , on the line for remote control or automatic signal control breaking breaking, while on the line from overload and short circuit protection, can be used as infrequent conversion of the lines operating with. At present, widely used in IC card prepaid meter to control the line supporting the use of on-off.
YDMS-63   IC pre-paid card control circuit breaker has a small, convenient installation, a residential meter charge control, the IC card when the prepaid balance of insufficient control circuit breaker automatically off, play the role of power, and so the user can continue to recharge closed.
IC pre-paid card control circuit breaker in line with IEC60898, GB10963, GB14048.2 standards, with international advanced level.

Second, model and specification

Third, the structural characteristics

YDMSIC prepaid card control circuit breaker from the YDMS MCB and intelligent modules assembled shunt release. We have instantaneous tripping and delay the trip in two ways.
Shell is made of flame retardant new arc-resistant high strength plastic, so the impact strength and good flame retardant properties. Contact system with electric repulsion mechanism, greatly improving the breaking capacity of the circuit breaker to breaker function more perfect and reliable, L extreme electromagnetic and thermal protection function, N pole electromagnetic protection, S highly a shunt off buckle function. Automatic winding of the shunt trip coil is subjected to 3300V (1.2/50μs) voltage test, meet the insulation level Ⅲ CEI28-6. Shunt trip life more than 4000 times.
Shunt trip coil having a limiting role in ensuring that the shunt trip coil current drawn lines, within a reliable security value, can effectively prevent the actual use of the process coil burning phenomenon. Shunt trip device designed as a single pole, anti-interference ability, can effectively prevent the shunt release in the electromagnetic interference and thermal interference malfunction.
IC card control prepaid breaker is designed for single-phase, three-phase four-wire meter IC card supporting the use and design, it has the inverse time overload and short circuit protection can receive IC card meter The signal cut off the circuit, to prevent users from arrears of electricity, it has been widely used in a form of a national power grid renovation project.

Fourth, shunt trip delay action feature

IC card control prepaid breaker The working voltage of any value in the range of 70% to 110%, and the use of circuit breakers and intelligent shunt to control the voltage applied to the release pole through the signal line, namely signal voltage (the distal end of the control line or by the meter IC card offer) and then switch on the circuit breaker handle to the closed position. When you need the remote control (or IC card meter arrears when) can be controlled by controlling the system voltage is disconnected, the circuit breaker should be able to reliably breaking in 0.5s≤t≤2s, while the circuit breaker also has short-circuit and overload functions.
