Common questions from systems integrators + IT infrastructure + automation engineering buyers sourcing Citel data-line SPDs through Vasundhara.
Power-line Type 2 SPDs protect the AC LV power supply only. Lightning + switching surges can also enter equipment via signal / data / telecom / coaxial lines — Ethernet cables running between buildings, telecom POTS lines from the street, coaxial cables to outdoor antennas, RS-485 instrumentation networks running across plant floors. A surge that bypasses power-line SPDs via the signal-line interface can damage the protected equipment regardless of power-line protection. IEC 61643 + IEC 62305 require protection on all incoming services (power + telecom + signal) — not just power. Data-line SPDs fill this gap.
Type 1, Type 2, Type 3 classifications apply to AC power-line SPDs per IEC 61643-11: Type 1 = lightning current (10/350 µs waveform), Type 2 = switching + indirect lightning surge (8/20 µs waveform), Type 3 = sensitive-equipment final protection. IEC 61643-21 covers signal / data-line SPDs with similar Type 1 / 2 / 3 classification system but for signal lines. Most data-line SPDs are Type 3 / Class III — they protect at the equipment-input interface for In 5-10 kA / Imax 10-20 kA on signal lines. Combined Type 1+2+3 data-line SPDs are available for installations requiring both lightning-current-rated + equipment-protection coverage.
Yes — Citel's RJ45 Ethernet SPD range includes PoE-compatible (IEEE 802.3af / 25.5 W) + PoE+ (IEEE 802.3at / 51 W) variants for Ethernet-power-over-cable applications. Standard for IP camera + IP phone + WiFi-AP installations where the access device is powered by PoE. Always verify PoE compatibility requirement during SPD selection — non-PoE SPDs will block PoE power-injection.
Insertion loss is the signal attenuation caused by the SPD between the protected equipment and network. For high-speed networks (1G / 10G Ethernet, high-frequency RF), low insertion loss is critical — typically <1 dB at the design signaling frequency. Excessive insertion loss can cause network performance degradation. Citel SPDs are specified with insertion loss per the bandwidth — ensures network design margin is preserved post-SPD installation. Always verify insertion loss against the network design margin during SPD selection.
Best practice: install data-line SPD at the entry point where the signal line crosses the building boundary or enters the protected equipment. Per IEC 61643-21 + IEC 62305: install at the demarcation point between outside-plant cabling and inside-plant equipment, and as close as possible to the protected equipment input. Ground bonding to the building's master earth bonding bar is critical for SPD performance. We provide SPD coordination engineering support including placement recommendations for projects where Vasundhara is the supply partner.
Citel offers data-line SPD variants for hazardous-area installations (Zone 1, Zone 2, Class I Div 1 / Div 2) — explosion-proof or intrinsically-safe (Ex i / Ex e) variants. For refinery / petrochemical / pharma installations requiring ATEX / IECEx-certified hazardous-area instrumentation, specify the appropriate Ex-certified data-line SPD variant during enquiry. Specialised supply on order — typically 4-6 weeks lead time for hazardous-area certified data-line SPDs.
