The BCH 001CB11 is an auxiliary contact block for compatible BCH NHD Series 4-pole contactors, providing a combination of 1 normally open (1NO) and 1 normally closed (1NC) auxiliary contact. It is designed to extend the control, signalling and interlocking functions of compatible NHD contactor assemblies.
The 001CB11 is part of the BCH NHD Series auxiliary contact accessory range. The 1NO+1NC arrangement provides two additional auxiliary contact paths that can be used independently within a control circuit according to the electrical control scheme.
The normally open contact can be used for functions such as contactor-status indication, auxiliary control logic or signalling, while the normally closed contact can be incorporated into interlocking, control or status circuits where a closed contact is required when the contactor is de-energized. Correct application depends on the complete control-system design.
The accessory is intended for use with compatible BCH NHD Series contactors and should be matched to the specific contactor model before ordering. BCH also lists other NHD auxiliary contact configurations, including 001CB10 (1NO), 001CB20 (2NO) and 001CB02 (2NC), allowing different contact arrangements to be selected for control-panel requirements.
Important: 001CB11 is an auxiliary contact block/accessory and not the complete NHD 4-pole contactor. It should be listed separately as a contactor accessory.

The BCH 001CB11 1NO+1NC auxiliary contact block can be considered for:
The BCH 001CB11 adds both a normally open and a normally closed auxiliary contact to compatible NHD contactor assemblies. This provides greater flexibility for control and signalling circuits without changing the main power-contact arrangement of the contactor.
The 1NO contact can be used for appropriate auxiliary control or indication functions, such as providing a contactor-status signal to a control circuit. The 1NC contact can be used where a normally closed auxiliary path is required for interlocking, control logic or status monitoring.
Using a dedicated BCH auxiliary contact block provides a convenient way to expand the functionality of a compatible NHD Series 4-pole contactor while maintaining an integrated contactor-accessory arrangement.
The BCH NHD auxiliary-contact range includes different contact combinations, allowing panel builders to select the appropriate configuration for their control requirements. The available options include 001CB10 (1NO), 001CB11 (1NO+1NC), 001CB20 (2NO) and 001CB02 (2NC).
The compact accessory format makes the 001CB11 suitable for industrial motor starters, automation panels and control assemblies where additional auxiliary contacts are required without installing a separate auxiliary relay.
For OEMs, panel builders, electrical contractors, automation integrators and industrial maintenance teams, the BCH 001CB11 provides a practical solution for extending compatible NHD contactor control functionality.
