SC20HWH

SC20HWH is a high-power, low-frequency static contactor widely used in power control, industrial automation and power systems. Its main feature is that it can be used as the main switch of high power circuit or as the connector of multiple power circuits. This article will discuss the application field and working principle of SC20HWH.

When it comes to the application field of SC20HWH, it is widely used in power control, industrial automation and power systems. It can be used as the main switch of high power circuit, providing protection from high magnetic fields or used as the connector for multiple power circuits. It is also applicable in welding equipment, with low frequency AC voltage and current control, short-circuit protection, and short-time current measurement.

As for its working principle, SC20HWH includes a rotor, stator, current transformer, normally closed contacts and armature winding. When the current is supplied to the stator, the rotor will rotate according to the magnetic field and close the contacts. Furthermore, when the current reaches a certain level, the armature winding will be affected and the contacts will open. When the current drops to a certain point, the contacts will close and the power will be restored. The current transformer allows the contactor to adjust the current, preventing overload and short circuit.

In conclusion, SC20HWH is a high-power, low-frequency static contactor with a wide application range. It is suitable for power control, industrial automation and power systems, providing protection from high magnetic fields or connecting multiple power circuits. Its working principle includes a rotor, stator, current transformer, normally closed contacts and armature winding. The current transformer allows the contactor to adjust the current, preventing overload and short circuit.
