Short circuit, overload and leakage protection. During normal operation and fault protection, when the circuit breaker is in the tripped position, both the phase line and neutral line are in the disconnected state, avoiding the neutral line being live during faults. When making and breaking operations, the neutral line connects first and disconnects later. It has short-circuit current limiting function and high rated short-circuit breaking capacity. It has overload protection, short-circuit leakage and voltage protection devices, with complete protection functions and convenient and reliable wiring.
Over and under voltage release: The fully automatic over and under voltage time-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. The protector can quickly and reliably switch the power supply under high voltage impact and under voltage conditions to protect household appliances. When the voltage returns to normal, after a time delay, it can automatically connect the circuit and restore power supply, effectively protecting appliances from the impact of instantaneous power-on. All functions are fully automated, no special operation is needed, and a dual-color light-emitting diode indicator is used, which is safe and fast.
Industrial power distribution system, short circuit and overload protection. Rated current 63A-125A, high rated short-circuit breaking capacity, with short-circuit current limiting structure. Complete protection functions, with overload and short-circuit protection devices, safe and reliable wiring, adopting "frame-type" wiring structure, easy function expansion, safe and reliable. Can be equipped with various accessories: leakage release, auxiliary contacts, alarm contacts, shunt release, under voltage release, busbar.
EPD surge protective device: EPD plug-in type adopts the same working principle and selection criteria as fixed surge protective devices. It protects against surges caused by indirect lightning and direct lightning effects or other transient overvoltages.
