Flush-mounted red button in OBC 2 NO/NC nickel-plated ring SP22-KC-20/OBC/B

Emergency break glass button for industrial and alarm systems

This red break glass button, in an OBC housing with a nickel-plated ring, is a reliable solution for triggering alarms or stopping processes in demanding industrial environments. It is designed for ease of use and durability, ensuring a quick response in emergency situations. The design with two contacts (2Z) allows for flexible configuration of signaling or control.

Construction and characteristics

The button is characterized by a solid construction made of plastic, resistant to mechanical damage. The IP55 protection class guarantees its tightness against dust and water jets, allowing for safe use even in difficult conditions. The presence of a protective glass further protects against accidental damage. The nickel-plated ring not only improves aesthetics but also increases corrosion resistance.

The button, after the glass is broken, requires manual pressing – this is important in situations where the priority is to prevent accidental triggering of the alarm. This solution ensures that the operator must consciously take action, minimizing the risk of false alarms.

Technical specifications and application

The SP22-KC-20/OBC/B button is used in safety systems, production lines, machines and equipment requiring immediate stopping or initiation of alarm procedures. Its dimensions (110 mm width, 148 mm height and 94 mm depth) allow for easy mounting in various configurations. Designed to operate in an ambient temperature of -40°C to +70°C, it meets the standards PN-EN 60947-5-1 and IEC 60947-5-1 and IEC 60947-1, which confirms its compliance with European safety standards. Connection cables should have a cross-section of 2× 1...2.5 mm² (solid wire) or 2× 0.75...1.5 mm² (stranded wire).
