The SRLW30 series universal transfer switch is mainly used for AC 50Hz, rated working voltage below 440V, rated current to 100A electrical circuit, used as the main switch of ventilation equipment, air conditioning and water pump system, and can also directly control small capacity AC motor.
The product complies with the standards GB14048.3 and IEC60947-3.
The SRLW30 series of switches are available in a wide range of current ratings from 20A, 32A, 40A, 63A, 80A and 100A.
The SRLW30 series switches are small in size, compact in structure, exquisite in material selection, well insulated, and have a finger-proof function. They are safe and reliable. Other contact blocks can be added to the 3-pole standard block without removing the switch.
The SRLW30 series switches have a large insulation distance and a fast disconnection speed, and are also suitable for DC circuits.
