How does an Intermatic surge protector work?
First, the Intermatic replaceable consumable models are built with an advanced thermally protected MOV technology (TPMOV) that disconnects the MOV from the circuit if the surge causes an overvoltage breakdown. That’s an important safety feature.
What is Type 1 surge protection?
OVR type 1 and type 1+2 are designed to discharge high current surges without any destruction of the installation. This surge protective device is chararcterized by its capacity to withstand impulse current with 10/350 µs wave form which simulate direct impact coming from a natural lightning current.
Are some surge protectors better than others?
A higher joule rating is the best indicator of greater protection. Choose a surge protector with a joule rating at the very least in the 200 to 400 range. Sensitive or costly equipment, such as computers, displays and audio/video equipment, warrants a joule rating of at least 1000.
What is Type 1 and Type 2 surge protection?
Type 1 – SPD which can discharge partial lightning current with a typical waveform 10/350 μs. Usually employs spark gap technology. • Type 2 – SPD which can prevent the spread of over- voltages in the electrical installations and protects equipment connected to it.
What is an intermatic panel Guard?
Intermatic PANELGUARD Surge Protective Devices are designed to react quickly to eliminate surges providing optimal protection to downstream equipment.
How does an HVAC surge protector work?
Surge protectors work by shunting current away from the appliance and into the ground. The most common type of HVAC surge protectors uses metal oxide varistors (MOVs) to control this flow. Varistors, as their name suggests, are devices whose resistance varies depending on the voltage applied across them.
What is the difference between Type 1 and Type 2 surge protector?
Type 1 – SPD which can discharge partial lightning current with a typical waveform 10/350 μs. Usually employs spark gap technology. Type 2 – SPD which can prevent the spread of over- voltages in the electrical installations and protects equipment connected to it.
What’s the difference between Type 1 and Type 2 SPD?
Type 1 SPD is characterized by a 10/350 µs current wave. The Type 2 SPD is the main protection system for all low voltage electrical installations. Installed in each electrical switchboard, it prevents the spread of overvoltage’s in the electrical installations and protects the loads.
Can you put a refrigerator on a surge protector?
We do not recommend connecting a refrigerator or freezer to a surge protector. The reason we do not recommend this is explained below: The compressor is sensitive to temperature and current overloads and will shut itself down with a power surge.
Is 1200 joules a good surge protector?
Units with surge protector ratings of 1000 to 2000 joules will provide sufficient protection for power tools and office equipment such as printers, copiers and routers.
