Detail Lockout Relay SIEMENS 7 PA
Fast acting electromechanical lockout relay Siemens Power Transmission Distribution
7PA22 and 7PA23 are fast-acting lockout relay with eight changeover contacts and four changeover contacts, respectively.
Due to their quality, reliability and design, these relays are optimal for applications requiring high reliability and availability such as power stations, substations, railway and industrial plants. Typical examples include petrochemical industry, chemical industry, cement industry, rolling mills etc.
The relays comply with the IEC, EN, IEEE standards ( type and routine test) and bear the CE mark.
The robust switch contacts are characterized by high make/ break capacity, overload capability and continuous current intensity capacity; thus perfect insulation is obtained. Direct control of high-voltage and medium-voltage switchgear is possible. Their high degree of protection and the transparent cover ensure reliable operation in tropical and/ or salty sea air ambient conditions.
