Review connector options for defined equipment interfaces, temporary feeders, testing and auxiliary supplies. Specify the exact AC or DC circuit before selecting a connection for an energy storage project.
A battery energy storage system can include battery-side DC circuits, power conversion equipment, AC distribution and auxiliary supplies. A connector suitable for one interface is not automatically suitable for the others.
Start with the equipment manufacturer’s connection specification. Identify whether the circuit is AC or DC, its operating voltage and current, its conductor arrangement and the required disconnection method. A three-phase AC connector set is not a generic specification for a battery-side DC connection.
Single-pole line source, line drain, panel source and panel drain connectors. Browse all four current ranges.
For equipment that specifies a PowerFit single-pole connection. Compare 400A, 500A, 750A and 800A ranges against the exact circuit and cable assembly.
Single-pole cam-type connectors in 150A and 400A ranges, with line and panel formats.
For temporary power or test equipment specifying a K-LOK cam-type interface. Confirm the rating and mating parts for the particular connection.
Multi-pole industrial plugs, connectors, receptacles and inlets. Select current, pole arrangement, voltage and protection grade together.
For AC auxiliary equipment or distribution specifying a matching CEE Form connection. Do not infer battery-side DC suitability from a CEE Form current rating.
16A · 32A · 63A · 125A

A connector’s maximum rating is a component limit. Select the complete connection, including both mating parts, cable, termination, enclosure and operating conditions. A larger connector rating alone does not establish the allowable current of the assembled circuit.
The referenced PowerFit 500A and 800A models specify 1000V AC/DC Maximum. Confirm the current datasheet for both sides of the connection.
For battery-side DC use, obtain explicit confirmation of suitability for the intended equipment and operating conditions. A voltage rating alone does not establish a complete battery-system interface, switching capability or system approval.
Connector datasheets, declarations and model-specific certificates are supporting documents for component selection. They do not establish certification of a complete battery energy storage system, a grid connection or a switchgear assembly.
Use the published PowerFit temperature-rise reports as evidence for their documented test configurations. They are not a blanket approval for continuous operation at the same current in a different enclosure, cable arrangement or ambient condition.
Include the circuit diagram, AC or DC designation, operating voltage and current, fault-duty requirements, equipment interface, cable details, environment and applicable project requirements. State whether the connector is for an equipment connection, temporary test feeder or auxiliary supply.
Send the interface, electrical requirements and cable details with your inquiry.
