✅ CHINT 574594 – NP2-BA54, Yellow, 2NC Contacts, Flush Button, IP40 Industrial momentary pushbutton with yellow actuator and dual NC contacts, suitable for simultaneous disconnection of two control circuits in logic inhibit or safety override functions. 🔹 Description (English): The CHINT 574594 – NP2-BA54 is a flush-mounted, momentary pushbutton switch featuring a yellow actuator and 2 normally closed (2NC) contacts, designed to provide dual-channel disconnection in applications that demand logic disable, interlock disengagement, or parallel safety shutdown. Upon pressing, both NC contacts open, allowing the operator to interrupt two independent circuits at once — a common requirement in systems with redundant safety inputs, dual-mode control logic, or lockout conditions. The yellow actuator offers clear visual distinction, often associated with cautionary or reset functions that must be acknowledged before restarting or releasing a process. Operating at AC380V, 50/60Hz, the switch supports spring-return operation, mounts into Ø22 mm panel cutouts, and is protected to IP40 level, making it suitable for indoor panels. The product complies with IEC60947-5-1 and holds international approvals from CCC, CE, UL, EAC, ACCE-NOM, and Ukraine. 🔹 Key Features: • Flush yellow actuator • 2 Normally Closed contacts (2NC) • Spring-return (momentary) operation • Rated voltage: AC380V (50/60Hz) • Designed for logic inhibit and dual-signal disconnection • Standard 22mm panel mounting • IP40 protection class • Complies with IEC60947-5-1 • Certified: CCC, CE, UL, EAC, ACCE-NOM, Ukraine 🔹 Technical Specifications (English): Parameter Value Model NP2-BA54 Part Number CHINT 574594 Actuator Color Yellow Contact Configuration 2NC Operation Type Momentary (spring-return) Rated Voltage AC380V, 50/60Hz Mounting Size Ø 22 mm Degree of Protection IP40 Standard Compliance IEC60947-5-1 Certifications CCC, CE, UL, EAC, ACCE-NOM, Ukraine Application Interlock / logic disable / dual-channel safety
