The 33E01 is a standard normally closed (N/C) contact block designed for use with BACO control stations and pushbutton assemblies. It features screw terminal connections for secure and reliable electrical connections, conforming to IEC 60947-5-1 standards. The contact block is rated for a maximum insulation voltage of 300V and can withstand impulse voltages of 4kV when used with a filter block. It is designed to mount directly into BACO's modular clip systems and can be stacked with other contact blocks for multi-function configurations. The 33E01 is commonly used in industrial control applications, emergency stop circuits, and signalling systems where normally closed contact functionality is required, offering a compact and cost-effective solution for panel-mounted control stations.
