AZM 170-02ZRK 230VAC, ABB part number 3BHB006872P0002, is a Schmersal-manufactured electromagnetic safety interlock lock specially specified for ABB medium voltage converter systems.

Operating at 230 VAC, this power-to-unlock safety switch secures cabinet access doors of high-power drive equipment. It adopts positive-break safety contact design with 2 NC safety contacts, complying with EN ISO 13849 machine safety standards. IP67 sealed thermoplastic housing delivers stable performance against dust and humidity inside converter rooms.

Built-in manual release allows authorised unlocking during maintenance. Max 1000N holding force prevents unintended door opening while equipment is energized.

The full part identifier 3BHB006872P0002 represents the ABB OEM ordering variant, ensuring perfect mechanical and electrical compatibility for direct replacement. Widely stocked as critical spare for ABB drive cabinet overhaul and safety system maintenance.

 

Access interlock protection is mandatory for medium voltage power converter cabinets to avoid hazardous electric shock risks. The AZM 170-02ZRK 230VAC (3BHB006872P0002) serves as the factory-matched safety solenoid lock for ABB drive systems.

The device keeps cabinet doors locked as long as control voltage is applied. Only after safe equipment shutdown and power cut can the interlock release the door. Dual safety contacts feed status signals to the drive control system for safety chain monitoring. Robust mechanical structure supports over one million operation cycles for long-term continuous industrial use.

Many metallurgy, power generation and mining facilities maintain inventory of this exact OEM part number. Generic alternative safety locks cannot guarantee matching mounting dimensions and safety circuit logic, making 3BHB006872P0002 the preferred spare for trouble-free cabinet maintenance.
