DIN-rail Type 2+3 SPD for cabinet installation close to sensitive loads, built on CITEL's patented VG technology — a gas-filled spark gap coordinated with a metal oxide varistor. Suited to final-circuit protection within the sub-distribution board serving PLC cabinets, instrument panels and control equipment. Consult the CITEL datasheet for In, Up and Uc figures for your supply voltage.
Single-phase Type 2+3 pluggable SPD with an integrated backup fuse, removing the need for a separate external fuse at the final circuit. Suited to protecting equipment supplies where panel space is limited. Pluggable cartridge design allows module replacement without rewiring.
True Type 1+2+3 combination SPD rated for direct lightning current, tested to the 10/350 µs waveform. Installed at the service entrance where a single device must cover lightning-current, switching-surge and final-line duty. Related parts: DAC1-13VGS and DACN1-35VGS.
DIN-rail protectors for data, signal and telecom pairs — DLA plug-in and DLU monobloc, in 6 V, 12 V, 24 V and 48 V variants. Tested to IEC 61643-21, which classifies data-line SPDs by category (C2, D1 and similar) rather than by the Type 1/2/3 scale used for power SPDs. For RS-485, 4-20 mA loops and telecom pairs.
DC-side Type 2 SPD for photovoltaic strings and inverter inputs, rated to 600 V, 1000 V and 1500 V DC. The DS50VGPV variant adds VG technology, and the /12KT1 suffix denotes a Type 1+2 rating for arrays with direct-strike exposure. The newer DPVN range covers the same duty.
All Citel Type 2+3 SPDs include thermal-disconnect indicators (window or remote contact) for end-of-life detection. Replacement modules available for cartridge-format SPDs (no rewiring needed). See Citel Replacement Modules page.
Standard property values across the range. TDS / MSDS / per-batch COA available on enquiry.
Electrical ratings differ by part number and by supply voltage, and CITEL publishes In, Imax, Up and Uc per variant rather than per family. Rather than reproduce a generic table here, we quote the exact ratings for the part selected against your single-line diagram and short-circuit data, and supply the corresponding CITEL datasheet with the offer.
Send your panel schedule and supply details and we will return part numbers with verified ratings, coordination notes and lead times.

Common questions from MEP + process-instrumentation + IT-cabinet installation buyers sourcing Citel Type 2+3 SPDs through Vasundhara.
Type 1 SPD at the building incomer reduces direct lightning + close-strike surge to ~2.5 kV. Type 2 at sub-distribution further reduces to ~1.5 kV. But PLCs (1.5 kV impulse withstand), servers (1.0 kV), and medical equipment (0.5-1.0 kV per IEC 60601) need residual voltage ≤ 1.0 kV at the protected load. Type 2+3 SPD installed within 10 metres of the sensitive equipment achieves this final reduction. Without Type 3, even properly-installed Type 1+2 may not adequately protect modern sensitive electronics.
Type 2+3 SPD must be installed within 10 metres of the protected equipment — closer is better. Typical installations: (1) inside the equipment cabinet itself (PLC cabinet, server rack PDU); (2) on the wall adjacent to the equipment; (3) as a plug-strip directly at the equipment power point. Long cabling between Type 2+3 SPD and equipment defeats the purpose — inductive voltage drop on the cable adds residual surge that Type 3 was meant to prevent.
Type 2+3 SPDs are sized by In (nominal discharge current, 8/20 µs) and Up (voltage protection level): (1) In ≥ 5 kA for most installations (sufficient since Type 1+2 upstream have already absorbed most of the surge energy); (2) Up ≤ 1.0 kV for PLC + server + IT equipment; Up ≤ 0.6 kV for IEC 60601 medical equipment. Standard Citel Type 2+3 SPDs deliver In 5 kA + Up ≤ 1.0 kV — covers 90% of installations.
DAC — DIN-rail mount Type 3 for installation inside electrical cabinets (PLC cabinets, sub-distribution boards). DLU — plug-strip Type 3 for direct insertion at equipment power point (server rack PDU, lab equipment, medical devices). DLA — Type 3 for data + signal lines (Ethernet, RS-485, 4-20 mA instrument loops). Most installations need both DAC (power-line) and DLA (data-line) for complete protection of equipment with both power + signal entries.
All Citel Type 2+3 SPDs include thermal-disconnect status indicators (window or remote contact) for end-of-life detection. Visual check after every lightning event in the area + monthly during routine inspections. Annual functional testing per IEC 61643-12 — measure leakage current, check Uc, verify status indicator. Replace SPDs immediately when indicator shows end-of-life — operated SPDs no longer protect. Typical service life: 5-15 years depending on local lightning activity + surge frequency.
DIN-rail Type 2+3 SPD (DAC series) installation requires a licensed electrician — wiring into the distribution board, proper grounding, lead-length compliance, isolation switches. Plug-strip Type 2+3 SPD (DLU series) for plug-in equipment can be self-installed by competent IT/maintenance staff — simply plug equipment into the SPD outlet, plug SPD into the wall. For data-line SPDs (DLA), follow OEM wiring diagrams + ensure proper grounding.
