This new modelSPD backup protectorThe main features are: maximum non trip discharge current Imax 120kA or maximum non trip impulse current Iimp 50kA.
Product model: HSCB440-40T2
SPD type: T2
Rated voltage: 440VAC
1、 Product Description:
This series of surge protector dedicated circuit breakers, also known as SPD backup protection devices or external (front) disconnectors SCB, completely solves the current safety hazards in the industry and achieves the best cooperation with lightning arresters. The main features of this new product are: maximum non trip discharge current Imax 120kA or maximum non trip impulse current Iimp 50kA; Low inductance design ensures that the residual voltage of the entire protection circuit is very low; Power frequency tripping current<3A, tripping time<0.5s; emergency channel design ensures that the circuit breaker still has corresponding lightning protection capabilities after tripping; Remote opening and closing operation (optional) remote alarm function, which sends a signal as soon as possible after tripping, indicating the closing operation or replacement (optional).
