Description

The ZH37 Switch-Disconnectors in Aluminium Enclosures are engineered for high performance and reliability in various industrial applications, including Power Distribution and Automation systems for Buildings, Power, and Petrochemical industries. These disconnectors effectively address critical needs such as emergency disconnection, safety disconnection, machine control, and motor control. With an integrated isolation, breaking, and switching function, they offer versatility by allowing easy transitions from Load Isolation Switches to Cam Switches, providing innovative solutions tailored to specific applications.

Designed with an instantaneous on/off mechanism, the contact force remains unaffected by external forces, ensuring consistent contact pressure and over travel stability throughout the handle’s operation. The switch housing is constructed from glass fibre reinforced unsaturated polyester resin, boasting exceptional Flame Resistance, Dielectric properties, Anti-Carbonisation, and Impact Resistance. Additionally, standard 3 pole Switch-Disconnectors can be expanded into 6/8 pole configurations with appropriate accessories, enhancing adaptability.

Installation is flexible, with options for Screw Installation, Rail Installation, or Door Installation. For added safety, the switch can be padlocked, accommodating locks with diameters of φ4-φ5mm. These disconnectors comply with standards EN60947-3 and GB14048.3 and are available with varying degrees of protection, IP20 or IP67, depending on the enclosure material.
