The Eaton NHI-E-11-PKZ0 auxiliary switch is designed for electrical professionals needing to add extra signaling or control contacts to compatible Eaton circuit breakers. Its key benefit is providing enhanced monitoring and operational flexibility within existing electrical systems. A primary consideration is its specific compatibility requirements with certain Eaton PKZM0 series components.

An auxiliary switch provides additional contacts that mirror the status of the main circuit breaker (e.g., tripped, on, off). These contacts can be used for remote signaling, control interlocking, or status indication in a larger electrical system.
The Eaton NHI-E-11-PKZ0 is rated for 250 V DC. While it might function in low-power AC control circuits, it is primarily designed and rated for DC applications. Always consult the detailed specifications for your specific AC application.
This typically refers to 1 normally open (NO) contact and 1 normally closed (NC) contact. The NO contact closes when the main breaker is in a certain state (e.g., ON), and the NC contact opens in that same state.
The maximum switching current for this auxiliary switch is 2 A.
The operating temperature range is from -25 °C to +55 °C.
It is designed for recess mounting and easily plugs onto compatible Eaton PKZM0 series circuit breakers.
No, this auxiliary switch is specifically designed and tested for compatibility with Eaton PKZM0 series and related Eaton circuit breakers.
Verify that the auxiliary switch is correctly seated on the circuit breaker. Check wiring connections to ensure they are secure and connected to the correct NO/NC terminals. Confirm that the associated circuit breaker is in the expected state (e.g., ON, OFF, Tripped).
Ensure you are using a compatible Eaton circuit breaker model from the PKZM0 series or a listed compatible series. Check for any obstructions on the mounting points of either the breaker or the auxiliary switch.
Carefully tighten the screw terminal using an appropriate screwdriver. Do not overtighten, as this could damage the terminal. If the terminal is stripped or damaged, the unit may need replacement.
Setup: The Eaton NHI-E-11-PKZ0 is designed for plug-on mounting. Ensure the compatible Eaton circuit breaker is de-energized before attempting installation. Align the auxiliary switch with the designated mounting points on the side of the circuit breaker and push firmly until it clicks into place. Connect the control wiring to the appropriate terminals on the auxiliary switch according to your circuit diagram.
Compatibility: This auxiliary switch is specifically designed for use with Eaton PKZM0, PKZM01, PKZM4, PKZM0-T, PKM0, and PKE series circuit breakers. Always verify compatibility with your specific circuit breaker model before purchase and installation.
Care: Keep the auxiliary switch clean and free from dust and debris. Avoid exposure to excessive moisture or corrosive environments. Periodically inspect wiring connections for tightness and signs of wear. No user-serviceable parts are inside; any damaged units should be replaced.
