WD1-SCB-A
Product Description
SPD special external disconnector (backup protector: SCB, It solves the problem of blind zone protection existing in the extensive use of fuses or circuit breakers as external disconnectors, and is an ideal supporting device for voltage switching SD and voltage limiting SPD in low-voltage power supply systems.
Featur
1. Large lightning impulse current (25kA10/350 μ S. 100kA8/20us no break - ensure SPD lightning protection is effective:
2. SPD fault power frequency continuous current breaking value is lower than 3A ± 1A to ensure power grid and power safety:
3. When the residual voltage of lightning impulse is low, the reliability of equipment lightning protection will be increased.
Ordering Instructions
1. Users shall indicate the product series, color, model, stage, current and quantity in detail when processing or ordering products.
2. SPD fault power frequency continuous current breaking value is lower than 3A ± 1A to ensure power grid and power safety:
For example, 20 sets of SCB series all black WD1-SCB-A/80/4P.
