SPD Surge Protection Unit Mini Circuit Breaker for D Grade Lightning Proof
SPD series D grade surge protective device (in short: SPD, alias: surge protector, surge arrester) is suitable for TN-S,TN-C-S,TT,IT etc. power supply system of AC 50/60Hz, ≤380V, installed on the joint of LPZ1 or LPZ2 and LPZ3, it's designed according to IEC61643-1,GB18802.1, it adopts 35mm standard rail, there is a failure release mounted on the module of surge protective device. When the SPD fails in breakdown for over-heat and overcurrent, the failure release will help electric device separate from the power system and give the indication signal,green means normal, red means abnormal, it's also could be replaced for the module when has operating voltage.
Product advantages:
Could be replaced for the module not need power cut.
Maximum current of endure the lightning-stroke 20kA (8/20μs).
Response Time <25ns.
The color of visible window shows operating status, white means normal,red means abnormal.
Application:
It's suitable for D grade lightning-proof, SPD,SPD1,SPD5 series surge protective device according to
GB188021.1-2002,installed on the joint of LPZ1 or LPZ2 and LPZ3, usually installed in household distribution boards, computer equipment, information equipment, electronic equip-ment and in the socket box in front of control equipment or near the control equipment. Notice:When you order our goods, please write the model and quantity carefully. For example: SPD-5/385/2, 8
pieces.
