The varistor surge protector from the OP series – model OP30s B+C, is a type 1+2 designed for 3-phase electrical installations 400\/230V 50Hz. The new version with the letter s is equipped with a NO\/NC signal contact, which can be used to monitor the protector’s failure. The signal contact features a miniature plug\/socket connection, which greatly facilitates installation and later service. The state change of the contact occurs when the cartridge is removed or damaged, for example, due to the activation of the thermal protection. The activation of the thermal protection is indicated by a change in the indicator color from green to red. The new OP30s B+C protector is fully interchangeable with the old OP30 B+C model.<\/p>\n
The OP30s B+C protector is used to protect electrical installations from surges, ensuring protection against damage to devices and electrical equipment.<\/p>\n
