What is the DZ-4B6 forward reverse electromagnetic motor switch?
The DZ-4B6 is an electromagnetic motor switch that combines electromagnetic switching with forward and reverse rotation control, so an operator can change the motor direction. It is built on the DZ08 series industrial electromagnetic switch platform.
What are the electrical ratings and enclosure data of the DZ-4B6?
It is specified for 250V~ / 400V~ and for a 3P+N+E 16A/380V~ configuration. At AC250V the ratings are AC-3:16A, AC-15:8A and 14(14)A; at AC400V they are AC-3:12A, AC-15:6A and 10(10)A. The ambient temperature class is T85/T55 with IP55 enclosure protection (IP54/IP55 sealed enclosure).
Which certifications and standards does the DZ-4B6 carry?
It holds TUV/CE approval to EN61058 and EN60947. The switch is manufactured in an ISO 9001:2015 facility whose in-house laboratories are certified by UL and T�V.
Can the DZ-4B6 serve as an alternative to KOA1/KOA2 type switches in three-phase equipment?
Yes. It is designed as a reliable alternative for applications that commonly use KOA1/KOA2 type electromagnetic switches and is intended for three-phase motor equipment. Compare the pole configuration and the AC-3 rating with the original switch before substitution.
Where is the DZ-4B6 used?
It is suited to industrial machinery, motor control panels, power distribution, pump and compressor control, process equipment and OEM equipment integration. In practice it fits equipment that needs both motor start/stop control and a change of rotation direction.
Is the DZ-4B6 customizable, and which documents are available?
The DZ08 platform covers 31 variants with different plug configurations and pole arrangements, and OEM customization as well as OEM equipment integration are supported. The official catalog drawing with dimensions and the electrical circuit diagram is available, with CAD files and 3D models on request; quotes, samples and technical datasheets are answered within 24 hours.
