1. Scope of application: Applicable to AC, voltage up to, DC up to, and current up to power distribution networks, used to distribute electric energy and provide overload, under-voltage and short-circuit protection for lines and power supply equipment, and
/> It is used for infrequently breaking and connecting power lines under normal working conditions.
2. Model and its meaning
3. Structural features The insulating base and cover are made of thermosetting plastic. The operating mechanism is a four-link type. Releases are divided into duplex type (equipped with overload protection and short-circuit protection), electromagnetic type (equipped with short-circuit protection) and thermal tripper type (equipped with overload protection). The wiring methods are divided into two types: front and rear. The insulating base and cover are pressed from thermoset plastic. The operating mechanism is a four-link type. Releases are divided into duplex type (equipped with overload protection and short-circuit protection), electromagnetic type (equipped with short-circuit protection) and thermal tripper type (equipped with overload protection).
