The BCH 001CB20 is an auxiliary contact block for BCH NHD Series 4-pole contactors, providing 2 normally open (2NO) auxiliary contacts for electrical control, signalling and interlocking functions. BCH's product documentation identifies 001CB20 specifically as the 2NO auxiliary contact block in the NHD range.
This component is designed to extend the control functionality of compatible NHD Series contactors by providing additional auxiliary contacts separate from the main power contacts. The 2NO configuration can be used for contactor-status signalling, control-circuit logic, electrical interlocking and auxiliary control functions according to the application requirements.
The 001CB20 belongs to the BCH NHD auxiliary-contact accessory range, which also includes 001CB10 (1NO), 001CB11 (1NO+1NC) and 001CB02 (2NC) configurations. This allows users to select the required auxiliary contact arrangement for different control-panel designs.
BCH specifies the NHD contactor series with encapsulated coils designed to withstand voltage fluctuations, along with rugged construction and weld-resistant contacts. The 001CB20 auxiliary block can be used with compatible NHD contactor assemblies as part of a complete industrial control system.
Important: 001CB20 is an auxiliary contact block, not the complete NHD 4-pole contactor itself. For product-page accuracy, it should be listed separately under NHD Auxiliary Contact Blocks / Contactors Accessories rather than as a standalone contactor.
The BCH 001CB20 2NO auxiliary contact block can be considered for:
The BCH 001CB20 adds two normally open auxiliary contacts to compatible NHD contactor assemblies, providing additional contact points for control and signalling circuits without altering the primary power-contact arrangement.
The 2NO configuration is useful where two independently usable normally open auxiliary contact paths are required. Depending on the control scheme, these contacts can be used for contactor status indication, control logic, electrical interlocking, signalling or auxiliary switching.
Using a dedicated BCH auxiliary contact block provides a practical way to expand the functionality of a compatible NHD Series 4-pole contactor while maintaining an integrated contactor accessory arrangement.
The BCH NHD accessory range provides several auxiliary-contact configurations, including 1NO, 1NO+1NC, 2NO and 2NC, allowing panel designers to select the required auxiliary contact combination for a particular application.
The compact auxiliary-contact construction makes the 001CB20 suitable for industrial control panels, motor starters and automation assemblies where additional control contacts are required without using a separate auxiliary relay.
For OEMs, panel builders, electrical contractors, automation integrators and industrial maintenance teams, the 001CB20 can provide a convenient accessory solution for expanding compatible NHD contactor control functionality.
