RM18D-125 Automatic-Reclosing Miniature Circuit Breaker
Product introduction
Product characteristics
Automatic-reclosing Miniature Circuit Breaker RM18D-125, is applicable for lines of AC 50Hz, rated
operating voltage up to 400V and rated current up to 125A. This product is used for conducting remote breaking to the circuits with automatic closing / opening control, with the function of protecting the lines from overload or short circuit. And also can be used as infrequent changeover of circuits. This item is
widely used for controlling the making and breaking of circuit with IC card prepayment watt-hour meter meters, and is suitable for workplaces like where the devices need remote control, where is
inaccessible or unattended, where timely maintenance is not available, and where power supply
continuity is high-required. This product meets the standards: GB10963.1 and IEC60898-1.and also
suitable to: STATE GRID《Technical Specification of External Circuit-breaker for Watt-hour Meters
Q/GDW 11421-2015》and CSG 《Technical Specification of External Circuit-breaker for Watt-hour
Meters in Low-voltage》.
Technical Specification
Features
1. Protection functions against overload, short circuit or over / under-voltage, and prevent from
switching on at failure, it is safer to use.
2. Anti strong magnetic interference;
3. Three patents for invention;
4. Disconnect quickly once there is failure at the instant of switching on to ensure safely, while the
contacts of circuit breaker are in fully opening or fully closing state all the time, avoid accident caused by the contact staying in the middle of opening or closing action due to fault.
5. Meter signal control opening / closing;
6. Convenient installation, outline width of single-pole is 18mm, the control part has the same height with that of breaker part, guide rail type installation, easy interchange.
7. Shell and parts are made of high-flame-retardant, high-pressure-resistant and impact-resistant
plastic.
8. The circuit breaker has the function of quick closing. Avoid the adverse effects of handle speed
difference during the automatic reclosing and opening, thus prolonging the service life of the product.
