主要技术特点

1. Excellent Explosion-Proof Performance

The YBX3 series features an advanced flameproof (Ex d) enclosure design. In the event of an internal explosion, the flameproof housing effectively prevents flame and pressure transmission to the surrounding environment. Explosion-proof markings include:

• Ex d I – Electrical equipment for coal mines
• Ex d II A T1–T4 / Ex d II B T1–T4 – Suitable for IIA and IIB explosive gas atmospheres
• Ex d II C T1–T4 – Suitable for IIC explosive gas environments

The standard enclosure protection level is IP55, providing excellent resistance against dust and water ingress for harsh industrial conditions.
