What is the DZ08-4A7 electromagnetic motor switch?
The DZ08-4A7 is an electromagnetic motor switch for power tools, workshop equipment and small industrial machinery. It uses a 2P+E 16A/250V~ configuration with TUV certification and provides reliable motor start/stop control with stable switching performance.
What are the electrical ratings of the DZ08-4A7?
The switch is specified for 250V~ / 400V~. At AC250V it is rated AC-3:16A, AC-15:8A and 14(14)A; at AC400V it is rated AC-3:12A, AC-15:6A and 10(10)A. The ambient temperature class is T85/T55.
What is the enclosure protection level and how is the DZ08-4A7 installed?
The housing is an IP54/IP55 sealed enclosure with multiple mounting configurations, and the high-current terminals support 2P+E, 3P+N+E and other pole configurations. The DKLD catalog drawing shows the dimensions and the electrical circuit diagram, and CAD files and 3D models are available for design teams.
Which certifications and standards apply to the DZ08-4A7?
It carries TUV/CE approval to EN61058 and EN60947 (TUV/CE (EN61058 EN60947)). Production takes place in an ISO 9001:2015 facility with UL- and T�V-certified in-house laboratories.
Can the DZ08-4A7 serve as an alternative to KOA1/KOA2 type electromagnetic switches?
It is designed for applications that commonly use KOA1/KOA2 type electromagnetic switches and offers a reliable alternative with AC-3 motor load capability and IP54/IP55 protection. The performance is comparable rather than identical, so compare the electrical ratings with the original switch before substitution.
How do I choose between the DZ08-4A7 and other DZ08 models, and can it be customized?
The DZ08 series covers 31 variants with different plug configurations and pole arrangements, so selection follows the required pole and plug configuration; the DZ08-4A7 is the 2P+E 16A/250V~ line. OEM customization and OEM equipment integration are supported, and requests for a quote, samples or technical datasheets are answered within 24 hours.
