The BCH 050N3 is a 2NC auxiliary contact block used with compatible BCH Type T oil-tight push buttons and control devices. It belongs to the Oil Tight Push Button & Indicating Lights – Type T, 30.5 mm range and provides two normally closed (2NC) contacts for control, interlocking, signalling and automation circuits. BCH's product documentation lists 050N3 as the 2NC contact-block option in this range.
The Type T range is designed for industrial control applications and includes non-illuminated and illuminated push buttons, flush and extended actuators, mushroom-head push buttons, selector switches, cylindrical-lock versions and indicating lights. BCH specifies the range with an IP65 degree of protection, rugged construction and suitability for motor control centres and control panels.
The 050N3 2NC contact block provides two normally closed auxiliary contact paths. These contacts can be used for suitable control-circuit logic, electrical interlocking, stop circuits, status signalling and other auxiliary switching functions according to the control-system design.
Important: The 050N3 is not a complete push button or indicating light. It is the 2NC contact block/accessory used with compatible Type T control devices. For accurate product classification on SB Smart, it should be listed as a BCH Type T 2NC Contact Block / Push Button Accessory rather than as a standalone push button.
The BCH 050N3 2NC contact block can be considered for:
The BCH 050N3 provides two normally closed auxiliary contacts for compatible Type T push-button and control-device assemblies. This allows additional control functions to be incorporated into a panel without requiring a separate auxiliary switching device.
The 2NC configuration is particularly useful for control schemes requiring normally closed contacts. Depending on the application, these contacts can be incorporated into stop circuits, electrical interlocking, control logic, status monitoring and auxiliary signalling.
The 050N3 forms part of the BCH Type T 30.5 mm oil-tight control-device family, which BCH describes as having an IP65 protection degree, rugged construction and suitability for motor control centres and control panels.
Using a dedicated BCH contact block allows compatible Type T push buttons and control stations to be configured according to the required contact arrangement. The range provides multiple configurations, including 1NO+1NC, 2NO and 2NC, allowing greater flexibility when designing electrical control circuits.
The 2NC contact arrangement can be useful in industrial automation and machinery-control applications where normally closed auxiliary paths are required for safe or coordinated control logic.
For OEMs, panel builders, electrical contractors, automation integrators and industrial maintenance teams, the BCH 050N3 provides a practical accessory for expanding the functionality of compatible Type T push-button assemblies.
