Having technical difficulties?
Our experts are here to help.

What is the difference between primary and secondary connectors?

Primary connectors are used for main power circuits (up to 630A), available in 3-pole and 4-pole configurations. Secondary connectors are used for control and signal circuits with multi-pin layouts.

How do I select the right current rating for a primary connector?

Choose based on the load current. We offer 125A, 250A, 400A, and 630A models for both 3-pole and 4-pole systems.

What is the maximum number of pins available for secondary connectors?

Standard secondary connectors support up to 24 pins, with 16-pin as the default configuration. Custom layouts are available.

Are these connectors compatible with non-standard cabinets?

Yes. We provide custom connector solutions tailored to specific cabinet layouts and electrical requirements.
