Switching element
Mainly used in common mode protection, but also often used for
differential mode protection in passive circuits.
Pressure limiting element
Mainly used in differential mode protection, it is also commonly
used in common mode circuits in series with switching elements to
prevent short circuit between the line and ground after the
switching elements are turned on; or as a current limiting element
of the switching element to block freewheeling and reset the
switching element .
Anti-overcurrent and overheating protection components
The anti-overcurrent components have self-recovery fuses, current
fuses, and resistors, and the anti-overheat protection and overheat
detection components have temperature fuse and temperature fuse. A
resettable fuse is a positive temperature coefficient thermistor.
When the current flowing through it is less than its holding
current (low temperature), its resistance is very small; when the
current flowing through it exceeds its trigger current (temperature
Increase), its resistance value increases sharply, thereby blocking
the continuous intrusion of lightning current or the freewheeling
of the circuit, and it can recover by itself after the temperature
drops. However, due to thermal inertia, the reaction speed is very
slow, generally in seconds (the greater the current or the higher
the temperature, the faster the reaction). Self-recovery fuses can
be used to replace current fuses, eliminating the trouble of
frequent replacement. Thermal fuse and thermal fuse are a kind of
temperature switch components, which are short-circuited during
normal operation. When the temperature is higher than the
disconnection temperature, the switch will be disconnected
(unrecoverable). They are often used for overheating protection and
overheating detection.
Shell material:
Using international brand nylon material and international brand
PBT material, the bending strength is in accordance with
GB/T9341-2008, and the impact strength of the simply supported beam
is notched and unnotched. Comply with GB/T1043.1-2008, flame
retardancy complies with GB/T2408-2008, excellent electrical
insulation performance, and strong consistency of product surface
technology.
Stamping:
It is made of high-precision copper, and the screws and locking
sleeves are electroplated after heat treatment. The advantage is
that the product is not easy to slip, the salt spray test can reach
72 hours, and the plugging force is moderate.
Elaboration
1. It is recommended that the maximum flow of SPD Imax: 10-60KA.
2. It is recommended that SPD be used in an environment of -40℃ to +100℃.
3. 1P, 2P, 3P, 4P can be distributed according to demand to meet various needs.
4.35mm guide rail design is convenient for subsequent installation.
