Short-circuit, overload, and leakage protection. During normal operation and fault protection, when the circuit breaker is in the open position, both the phase line and the neutral line are in the disconnected state, avoiding the neutral line being live during a fault. When performing closing and opening operations, the neutral line is closed first and opened last. It has short-circuit current limiting function and high rated short-circuit breaking capacity. It is equipped with overload protection, short-circuit leakage protection, and voltage protection devices, providing comprehensive protection functions and convenient and reliable wiring.
Over and under voltage release: The fully automatic over and under voltage delay protector is a new generation product developed by our company based on market needs. This protector has a reasonable design and is assembled with imported components and domestic brand components. It can quickly and reliably switch the power supply under high voltage surges and undervoltage conditions, protecting household appliances. When the voltage returns to normal, it can automatically connect the circuit and restore power supply after a delay, effectively protecting appliances from the impact of instantaneous power surges. All functions are fully automated, requiring no manual operation. It uses dual-color LED indicators for safety and convenience.
Industrial power distribution systems, short-circuit and overload protection. Rated current 63A-125A, high rated short-circuit breaking capacity, with short-circuit current limiting structure. Comprehensive protection functions, equipped with overload and short-circuit protection devices, safe and reliable wiring. Adopts "frame-type" wiring structure, easy expansion of functions, safe and reliable. Can be equipped with various accessories: leakage release, auxiliary contacts, alarm contacts, shunt release, undervoltage release, busbar.
EPD surge protector: EPD plug-in type adopts the same working principle and selection criteria as fixed surge protectors. It protects against surges caused by indirect and direct lightning effects or other transient overvoltages.
