TE Connectivity / Kilovac

TE Connectivity / Kilovac high-current DC switching

The TE Connectivity / Kilovac collection focuses on the category of high-current DC relays and contactors. These electrically controlled switching devices connect or disconnect a power path when directed by a separate control circuit. Correct selection depends on the requirements of the complete electrical system, including the load, control method, switching conditions, mechanical arrangement and intended operating environment.

No model-level details should be inferred from the collection name alone. Individual items may differ in electrical limits, contact configuration, terminals, enclosure, mounting and control requirements. Use each product's published documentation as the authority for purchasing decisions, and compare every relevant value with a documented system requirement before selecting a TE Connectivity / Kilovac component.

Understanding published technical information

Electrical ratings describe different operating limits and should not be treated as interchangeable. Continuous carry current concerns an established closed contact, while make and break ratings concern the switching event. Contact voltage applies to the main power path, while coil or control voltage applies to the command side. These requirements must be assessed independently using the values explicitly published for the product under consideration.

Mechanical and environmental information is also important. Dimensions, terminal form, mounting orientation, enclosure details and cable routing affect how a component can be incorporated into an electrical design. Temperature limits, vibration information, sealing details, isolation data and duty guidance, where published, help define the operating envelope. Protective devices, conductor selection and switching strategy remain part of the wider system design and should be assessed by an appropriately qualified person.

How to choose a TE Connectivity / Kilovac component

Begin with the shopper's documented electrical and operational needs rather than a preferred item name. Record the system voltage, expected load, switching conditions, control supply, available installation space and relevant environmental conditions. Then compare those needs line by line with the published specifications for each TE Connectivity / Kilovac relay or contactor. Keep an option under consideration only when every mandatory purchase criterion is explicitly supported by its documentation.

• Load requirements: Compare the required continuous and switching performance with the published electrical limits.
• Control requirements: Confirm the documented coil or control voltage, control current and required control arrangement.
• Switching behaviour: Check whether contact state, switching frequency and duty guidance align with operational needs.
• Mechanical criteria: Review dimensions, mounting method, terminal style, cable approach and available space before purchase.
• Operating conditions: Compare published temperature, ingress, vibration and isolation information with the intended environment and risk assessment.

For the final comparison, separate mandatory criteria from preferences. Mandatory criteria include electrical limits, control requirements and operating conditions that the design cannot safely vary. Preferences may include terminal format, mounting convenience or service access, provided every mandatory requirement is satisfied. When information is absent or unclear, request confirmation rather than inferring suitability from the TE Connectivity / Kilovac name or the collection category.
