SURGE-BLOK

Surge-Blok is an advanced, certified surge protection device to protect your entire home or commercial establishment from transient, over-voltages and lightning. As modern buildings rely on sensitive electronic controls, the need to protect against ongoing power variants has never been more important. Surge-BLOK protects every circuit from the electrical service.  The most reliable surge protection technology is now in a simple, easy to install platform.

Features

Surge-BLOK protects every circuit from the electrical service. The most reliable surge protection technology is now in a simple, easy to install platform. Heat-Line Surge-BLOK employs Strikesorb® technology from Raycap, non MOV, non-sacrificial surge protection technology that will not fail. Surge protection for your entire home or commercial establishment from transients, over-voltages, and lightning. Normal operation is indicated by the illumination of the green LEDs. In the event of a fault or loss of power, the LEDs will turn off. The Form C relay contacts may be configured to notify a remote alarm system of a problem using either the normally open or normally closed contact.

Part Number: 120-2S-S3-2-06-A-HL

Suitable for use on a circuit capable of delivering not more than 200,000 rms symmetrical amperes, 150V maximum, when protected by a RK5 class fuse, or a circuit breaker rated at 50A or less (2 Port Connection). It is intended for Service Entrance where there is a local N-G bond nearby. There is no N-G suppressor.

Part Number: 120-2S-M3-3-06-A-HL

Suitable for use on a circuit capable of delivering not more than 200,000 rms symmetrical amperes, 150V maximum, when protected by a 100A RK5 class fuse. It is intended for a sub panel or a panel where there is no N-G bond nearby.

Q – What is the difference between the two Surge-BLOK models?

A – The smaller box is the 120-2S-S3-3-06-A-HL and is intended for Service Entrance where there is a local N-G bond nearby. There is no N-G suppressor

The larger box is a 120-2S-M3-3-06-A-HL and this unit would be for a sub panel or a panel where there is no N-G bond nearby.

Q – After an electrical Surge, do you need to replace the Surge-BLOK, or is it good for multiple strikes?

A – The Strikesorb modules will take repeated surges/strikes without degradation. The units require no maintenance and they should only be replaced if the modules operate to an end of life. Should the modules operate to an end of life they will trip the upstream overcurrent protector (breaker) and the LED’s will go out.

Q – What is the MTBF (mean time before failure)?

A – In order to determine this one needs to know how many surges the units will be exposed to and what are the surge currents associated with each hit. A study was done regarding the use on wind turbines. The study concluded that based on the number of lightning strikes a wind turbine would have the Surge-BLOK device would last 200 years before needing to be replaced.

Q – How do you know if the Surge-BLOK needs to be replaced?

A – Breaker feeding the SurgeBLOK unit will trip. At this point, the modules should be measured with a simple resistance meter and if there is any resistance measured the modules are dead and need replacement.

Q – Will one Surge-BLOK protect my home AND my outbuildings?

A – Surge-BLOK should always be installed at the main service entrance to a facility. If electrical equipment in an outbuilding is to be protected from lightning strikes you should also install a Surge BLOK at the service entrance of the outbuilding.

Q – How is Surge-BLOK different compared to the other surge protection devices on the market?

A – The Strikesorb modules do not contain any internal fusing or thermal disconnects which are found in all other SPDs. These thermal disconnects limit the amount of energy the SPD can handle. The majority of other SPD’s use very small MOV’s in parallel in an effort to absorb and divert lightning strikes. There is no way each MOV in a multiple array can equally share surge currents. Strikesorb utilizes a single proprietary “Distribution Class” MOV, sealed under pressure in a strong aluminum enclosure. One MOV does the work, there is no need for “sharing” surge currents. The Strikesorb module is a mechanically strong SPD. There are significant lorenze forces associated with a large lightning strike. This causes SPD’s with a weak mechanical design to explode when hit with a significant surge.  Strikesorb has also been tested to the international IEC standard for Surge protectors and is certified as a Class I Surge protector able to take direct lightning. The vast majority of North American SPD’s are not tested to or certified to IEC Class I tests.
