Where Citel Type 2 SPDs ship from our Hyderabad warehouse — by industry segment and panel type.
DS200 / DS250 at the LV main switchboard downstream of the LV transformer + main breaker. Protects MCC drives, plant lighting circuits, instrumentation power, and downstream sub-panels. Standard for cement plants, steel plants, pharmaceutical plants, food & beverage plants — anywhere transient surges from inductive switching or lightning matter.
DS200 at sub-distribution panels feeding lighting, equipment, HVAC, lifts. DS40 at final-circuit boards for sensitive electronics — automation cabinets, PLC enclosures, drive panels, CNC controller cabinets. Cascaded Type 2 protection delivers Up <1 kV at sensitive equipment terminals.
DAC50 DC SPD on the DC side at the string-combiner box and inverter input. DS200 AC SPD on the AC side at the inverter output and grid-tie point. Critical for rooftop solar + ground-mount utility solar installations — high lightning exposure on solar arrays makes SPD specification mandatory per IEC 62305 / IS 15652.
DS50 spark-gap variants at telecom power feeders — low leakage current matters for IT-system protection compliance. DS200 at data centre LV main + sub-panels. UPS input + bypass-line protection critical for uptime — surge events can damage UPS rectifiers and tripping relays simultaneously.
DS200 at pharma plant LV mains; DS40 at downstream cleanroom equipment panels (autoclaves, BFS lines, blister-pack control panels). Hospital power — DS50 at OT (operation theatre) feeders, MRI/CT power lines, ICU equipment circuits where IT systems require spark-gap-based zero-leakage SPDs.
DS250 high-capacity Type 2 at process-plant outdoor panels with high lightning exposure — petrochemical loading bays, refinery field cabinets, mining plant panels. Where Type 1+2 combined protection (DLA / DUO series) is preferred, single-device installation simplifies the main-incomer SPD layout.

Common questions from MEP consultants, panel-builders, and EPC project teams sourcing Citel Type 2 SPDs through Vasundhara.
A Type 2 (Class II) Surge Protection Device is rated for protection against indirect lightning currents and switching surges (8/20 µs waveform). It's installed downstream of any Type 1 SPD, typically at LV sub-distribution panels, motor control centres, lighting circuits, and final-circuit boards. Type 2 SPDs are characterised by their In (nominal discharge current, typically 5-40 kA) and Imax (maximum discharge current, typically 15-70 kA) ratings per IEC 61643-11. The Citel DS200 series (In 20 kA, Imax 40 kA) is the most common Type 2 specification across Indian industrial and commercial installations.
DS40 (5 kA / 15 kA, Up ≤1.5 kV) is for downstream final-circuit protection — lighting, sockets, equipment panels — where upstream Type 2 SPD is already installed. DS200 (20 kA / 40 kA, Up ≤1.5 kV) is the workhorse Type 2 — installed at sub-distribution boards or as the main Type 2 protection in moderate-exposure buildings. DS250 (40 kA / 70 kA, Up ≤1.4 kV) is for high-exposure installations or when only a single Type 2 device is preferred at the main incomer in lieu of cascaded protection. Selection depends on Lightning Protection Level (LPL) per IEC 62305 and panel position in the SPD cascade.
All four meet IEC 61643-11 specifications with comparable protection performance at equivalent kA ratings. Citel's structural advantages: (1) French manufacturer with focused SPD specialisation since 1937 (vs SPD as one-of-many product line for the others), (2) Wide spark-gap technology range — important for IT-system, medical, and telecom applications where low-leakage matters, (3) Pluggable cartridge architecture across all series simplifies field maintenance, (4) Strong India presence with stable distribution and stocking. For OEM panel-builders standardised on Phoenix or Schneider for system-coordination reasons, those alternatives are equivalent. For specification-driven selection (especially where spark-gap or DC SPDs are required), Citel typically wins on technical fit.
It depends on the building's lightning protection classification per IEC 62305. Buildings with external Lightning Protection System (LPS — air terminals / down-conductors) require Type 1 SPD at the main service entrance to discharge direct-strike lightning currents (Iimp 10/350 µs waveform), followed by Type 2 SPDs at sub-panels for residual overvoltage. Buildings without external LPS (most urban commercial / industrial buildings without rooftop LPS) typically require only Type 2 protection at the main incomer + downstream cascade. The Type 1+2 combined SPD (Citel DLA series) covers both functions in one device — useful where panel space is constrained. We recommend a project-specific risk assessment per IEC 62305-2 before SPD specification.
Service life depends on lightning exposure and the cumulative surge energy absorbed. In moderate-exposure installations (typical Indian urban commercial / industrial), expect 8-12 years of service. In high-exposure installations (rural plants, solar PV arrays, mining sites), expect 5-8 years. The mechanical fault indicator (red flag visible through the cartridge window) signals end-of-life when MOV degradation crosses the threshold. Pluggable cartridges allow field replacement without rewiring — typical replacement time is 2-5 minutes per cartridge with the panel power isolated. Vasundhara stocks replacement cartridges for installed-base service.
Yes — IEC 61643-11 / IEC 60364 requires SPD upstream protection to disconnect the device safely on end-of-life short-circuit failure mode. Citel datasheets specify the maximum upstream backup-protection rating per SPD model — typically a gG-class fuse (e.g., 125 A gG for DS200, 160 A gG for DS250) or equivalent MCB. Where the upstream main protection already meets this rating, dedicated SPD backup-protection may be omitted; otherwise install a dedicated SPD-disconnect fuse or MCB in series with the SPD. We provide upstream-protection sizing as part of the SPD coordination engineering for projects where Vasundhara is the supply partner.
