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 a fault. When performing closing and opening operations, the neutral line is connected first and disconnected last. 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 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 product can quickly and reliably switch power under high voltage surges and undervoltage conditions, protecting household appliances. When the voltage returns to normal, after a delay, it can automatically connect the circuit and restore power supply, effectively protecting appliances from the impact of instantaneous power surges. All functions are fully automated, no special operation is required, and it uses dual-color LED indicators for safe and quick indication.
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. Complete protection functions, with overload and short-circuit protection devices, safe and reliable wiring, using "frame-type" wiring structure, easy function expansion, 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 uses the same working principle and selection criteria as fixed surge protection. It protects against surges from indirect lightning, direct lightning effects, or other transient overvoltages.
