MYS20-320/20-2P Class C surge protector with remote signaling alarm device for lightning protection of AC equipment
Description
MYS20-320/20-2P (S) is a Class C surge protector with a remote signaling alarm device.
Features
Selection of high-quality varistors, high reliability, quality assurance, and stable performance
Modular design can be plugged and unplugged when powered, convenient for testing or replacement
With a remote alarm device for easy remote monitoring
Using temperature-controlled circuit breaker technology, dual automatic protection circuits for overcurrent and overvoltage
With work and fault display, the deterioration status is clear at a glance
Product fundamentals
The SPD is connected in parallel between the line and the ground. Under normal operating voltage, the MOV is in a high-resistance state, which is equivalent to the line being open to the ground and does not affect the normal operation of the line. The fault display window is green, as shown in Figure 2.
When an instantaneous pulse overvoltage occurs on the line due to
lightning or switching operation, the lightning protection module
quickly conducts in nanoseconds, short-circuiting the overvoltage
to the earth and discharging it. When the pulse overvoltage
disappears, the lightning protection module automatically returns
to high voltage. resistance state, does not affect the user's power
supply. When the lightning protection module works in an overloaded
state for a long time, and its performance deteriorates when it
heats up to a certain temperature, the thermal protector (K1) in
the module (as shown in Figure 3) will automatically disconnect the
lightning protection module circuit to protect the power circuit.
Work will not be affected and fires will be prevented in time.
When excessive lightning current is induced in the line, the
overcurrent protector (K2) is quickly disconnected to prevent the
SPD from exploding. K1 or K2 action
Then, the tripping device in the SPD acts, causing the fault
display window to display red (as shown in Figure 4), reminding the
user to replace the SPD. At the same time, the tripping device
drives the remote signaling alarm switch (SK) to act and output a
fault alarm signal.
Application
MYS20-320/20-2P (S) is mainly used for lightning protection of AC equipment 230V system and operation over-voltage protection.
