Surge Protection Technologies

Strikesorb® – a unique MOV technology

Wherever deployed, Strikesorb technology will significantly improve the availability of the equipment it protects.

Key Benefits

Raycap’s Strikesorb technology is a surge protection solution that ensures vital equipment does not experience downtime due to lightning or other power surge events. Strikesorb’s unique design features a distribution-grade metal oxide varistor (MOV) that can handle much larger surges without affecting performance.

The company has made significant R & D and operational investments in developing and validating Strikesorb to meet global safety standards. Strikesorb has been engineered and tested for use in AC and DC power applications, and the Strikesrob 30, 40, and 80 modules are compliant with IEC 61643-11 and the UL 1449 5th Edition Standards. The Strikesorb 35 is for DC applications and is classified as Class I and Class II SPD according to IEC 61643-31 and as Type 2 Component Assembly according to UL 1449 5th Edition.

ProTec T1S Featuring Phase GDT Technology

Raycap’s Phase-GDT (PGDT) has been developed to optimize both Voltage Switching and Voltage Limiting SPD technologies to create an ideal Class I SPD in a DIN Rail design – where a compact package is possible using voltage-switching technology but without the drawbacks of a high residual voltage or poor follow-current rating. ProTec T1S utilizes a breakthrough multi-cell, encapsulated GDT technology, to achieve a residual voltage like that of an MOV-based SPD, but in a footprint half the size of the market competition and without restrictions governing where on a network it may be installed.

Key Benefits

  • Compliant with IEC Class I testing per IEC 61643-11 – making it suitable for use in locations where direct or partial lightning currents can be expected per IEC 62305-4.
  • Change over contacts for remote monitoring VDE mark – certified to applicable IEC and European norms under low voltage directives.
  • High surge capacity but without the problems of follow-current extinguishing – can be installed on networks having high prospective short circuit fault currents (ISCCR).
  • Tested to be suitable for repeated operations on networks with Ip as high as 50 kA 50/60 Hz.
  • Multi-cell design reduces follow-current to the point it behaves much like MOV-based technology – unlike conventional spark gap technology, where the high follow-current causes the gap electrodes to degrade after each operation, PGDT provides a long operational life.
  • Low residual voltage Up= 1.5 kV – can effectively be coordinated with other Class II or Class III SPDs on the network. It can be coordinated with any properly installed Class II SPD without considering cable length between the products.
  • High surge rating in a compact, pluggable DIN package – half the footprint of competitive products optimizes panel board real estate.
  • Encapsulated design; vital parts are housed inside a hermetically sealed cell – no expulsion of hot, conductive, ionized gasses.
  • Improved design ergonomics – features a retaining clip against vibration and shock.
  • Efficient internal mechanical and thermal disconnects – enable safe and reliable end-of-life behavior on networks.
  • Red/Green status indicator

SafeTec Surge Protection Technology

SafeTec technology is an open circuit mode in combination with current limiting technology. This limiting control prevents permanent disconnection during adverse temporary overvoltage (TOV) conditions. SafeTec delivers a reliable solution for all overvoltages, surges, and transients.

Key Benefits

SafeTec technology serves as a current limiter in the event of unexpected faults in power supply networks and ensures that the maximum current through the MOV in the initial state of conductivity is a few amperes. The current balance is quickly established at a level of about 10 mA. The unique SafeTec technology ensures that the current does not exceed the MOVs energy handling capability and prevents unwanted SPD disconnection from the power supply. The all-in-one technology is suitable for all AC applications and DC applications.
