CRITEC Dinline	The CRITEC Dinline Surge Filter is designed for the protection of strategic equipment or those sub circuits supplying critical applications. As well as providing shunt protection, it filters the clamped waveform to reduce the rate of voltage rise, providing superior protection for sensitive electronic equipment. The CRITEC Dinline range is available in all common voltages, such as 240, 110, and 24 Volt, and in current ratings of 6 amp and 20 amp The CRITEC DSF6A30V is specifically designed for process control applications to protect the 24V DC side of switched mode power supply units on devices such as PLC controllers, SCADA systems and motor controllers. Features: • Easy installation on 35mm DIN rail mountings • Compact design fits into most switch & distribution boards • Electronic power indicator ideal for poorly illuminated locations • EMI/FRI noise filtering • Three Mode protection L-N, L-G, N-G • C-Tick and CE Approved. DSF6A30V is also NOM Approved Applications: • Power surge and transient protection for sensitive electrical and electronic loads • Protection of sub circuits or specific equipment which may be remote from point-of-entry protection • Ideal for inclusion in switchboards • 24V ac/dc surge and transient protection for control equipment • Protection for rail and transit signal and communication systems Models Ordering information   Part No. Description DSF 6A 30V DINLINE Surge Filter - 1 Phase 2W+G, 6A Series Filter, 30V DSF 6A 150V DINLINE Surge Filter - 1 Phase 2W+G, 6A Series Filter, 150V DSF 6A 275V DINLINE Surge Filter - 1 Phase 2W+G, 6A Series Filter, 275V DSF 20A 275V DINLINE Surge Filter - 1 Phase 2W+G, 20A Series Filter, 275V Technical Information TNCR006 Technical Note SPDs and the befit of filtering Installation DSF Installation instructions
CRITEC TDS	The CRITEC TDS Surge Filters are designed for process control applications, to protect the switched mode power supply units on devices such as PLC controllers, SCADA systems and motor controllers. Units are available for 3A, 10A and 20A loads and in a range of clamping voltages 150V and 275V. The range is intended for use in conjunction with CRITEC Universal Transient Barriers (UTBs) to provide a coordinated approach to protection of both the power and data control circuits. The space efficient low pass filter, provides up to 62dB of attenuation to voltage transients, to further reduce the steep rates of voltage and current rise, providing superior protection for sensitive electronic equipment. Features: • Compact design fits into most distribution panels and motor control centers • High efficiency sine wave filtering - ideal for the protection of switched mode power supplies • 35mm DIN rail mount • Fail-safe LED indication and opto-isolated output for remote status monitoring • High surge rating 50kA ensures long service life • UL 1449 , UL 1283 and CSA 22.2 recognized, C-Tick, CE approved • Transient Discriminating technology ensures safe operation during abnormal over-voltage events Applications: • Power surge and transient protection for sensitive electrical and electronic loads                               • PLCs                               • SCADA                               • Motor Controllers                               • RTUs • Protection of sub-circuits or specific equipment which may be downstream remote from point-of-entry protection • Protection for rail and transit signal and communication systems Models Ordering information   Part No. Description TDF3A 240V 240V 1 phase 2W+G, 50kA 8/20µs, 3A series protector TDF10A 240V 240V 1 phase 2W+G, 50kA 8/20µs, 10A series protector TDF20A 240V 240V 1 phase 2W+G, 50kA 8/20µs, 20A series protector Technical Notes Installation Installation instructions TNCR005 Transient Discriminating Technology TNCR006 SPDs and the benefits of filtering
CRITEC TSG SRF	CRITEC TSG SRF Surge Reduction Filters use core state-of-the-art technologies, including ERICO’s Triggered Spark Gap (TSG) and Transient Discriminating (TD) which have been combined with efficient low-pass filtering, to provide the premium performance Surge Reduction Filter Technology. Features: • Incorporates TSG and TDS technologies • High surge rating 130kA (8/20µs), 50kA (10/350µs) • Designed for lowest possible let-through voltage under all surge magnitudes • Unsurpassed lifetime • Housed within a compact enclosure with escutcheon panel for personnel safety • High temporary over-voltage withstand to ensure safe operation and extended lifetime in real-world conditions • Designed to both the IEC and UL standards • Approved to AS3100, C-Tick, Certificate of Suitability Applications: • Surge Reduction Filters should be used at the point-of-entry to a facility for protection of sensitive equipment, or installed downstream of the point-of-entry diverters to protect dedicated Critical systems and equipment. CRITEC TSG SRFs are recommended for installation on the input supply to UPS equipment, which will ensure that critical loads are provided with a great level of voltage protection, in any event where the UPS transferred to bypass either through fault conditions, or during maintenance.   Models Ordering information   Part No. Description TSG SRF140 TSG, SRF, 1 PH, 40A, 220 to 275V TSG SRF163 TSG, SRF, 1 PH, 63A, 220 to 275V TSG SRF1125 TSG, SRF, 1 PH, 125A, 220 to 275V TSG SRF340 TSG, SRF, 3 PH, 40A, 220 to 275V TSG SRF363 TSG, SRF, 3 PH, 63A, 220 to 275V TSG-SRF3125 TSG, SRF, 3 PH, 125A, 220 to 275V TSG SRF3200 TSG, SRF, 3 PH, 200A, 220 to 275V TSG SRF3400 TSG, SRF, 3 PH, 400A, 220 to 275V TSG SRF3630 TSG, SRF, 3 PH, 630A, 220 to 275V TSG SRF31250 TSG, SRF, 3 PH, 1250A, 220 to 275V TSG SRF32000 TSG, SRF, 3 PH, 2000A, 220 to 275V Technical Notes Installation Installation instructions TNCR006 SPDs and the benefits of filtering
