Difference Between WAGO 221 and WAGO 222
1. Introduction: The Evolution of WAGO 221 and 222
WAGO is a well-known brand in the electrical industry, offering high-quality, safe, and easy-to-use wire connectors. The WAGO 222 series was introduced as a revolutionary lever-operated connector, making wiring faster and more reliable ( Designed 2004 ). Later, the WAGO 221 series was developed as an upgraded version, providing a more compact, efficient, and user-friendly design. Both series ensure secure and durable wire connections, meeting industrial and household electrical needs. ( Designed 2014 )
2. Material & Fire Resistance
- WAGO 222 is made from nylon, a strong and durable material that offers good electrical insulation.
- WAGO 221 is made from nylon and polycarbonate (PC), which enhances transparency and mechanical strength.
Fire Resistance & Features:
- WAGO 222: Flame-retardant, but has an opaque body, making it harder to inspect wire connections.
- WAGO 221: Also flame-retardant but with a transparent housing, allowing users to visually confirm correct wire insertion.
