They are designed to power a hand-held power tool with a voltage of 127V or 220V, lighting, automation circuits and alarms. There is also the possibility of connecting local lighting up to 0.2 kW.
The electrical circuit of the APShD unit provides protection against short-circuit currents in the outgoing power circuits and in the primary winding of the power transformer; protection against overloading of current collectors; protection against earth leakage currents; blocking the inclusion of the outgoing connection with a decrease in insulation resistance of the power wires below the critical one; protection against loss of controllability in the event of a break or excessive increase in the resistance of the ground circuit and when the remote control circuit is closed; zero protection; protection against self-switching when the mains voltage is increased.
On each outgoing connection it is possible to reverse the hand power tool. It is possible to supply current collectors with voltages of 220 or 127V.
They are designed to protect electrical installations from short-circuit currents as well as for operational switching on and off of electrical circuits under normal operating conditions in three-phase AC networks with a frequency of 50 Hz with an isolated neutral when installed in coal mine workings dangerous for gas (methane) and coal dust.
Provide protection: zero, short-circuit currents, blocking when the insulation resistance of the outgoing connection decreases, loss of control when the remote shutdown wires are closed or broken.
Explosion-proof spark-safety PIDID series are designed for remote control of the switching on and off of three-phase asynchronous squirrel-cage induction motors operated in three-phase alternating current networks with a frequency of 50 Hz with isolated transformer neutral in coal mines which are dangerous for methane and / or coal dust and for protection against short-circuit currents and overload in the outgoing power circuits.
The starters are manufactured in reversible version (switching is carried out by means of a disconnector). The starters are designed to control one electric motor or two independent electric motors.
The starters do not emit electromagnetic interference on the control, protection, telecommunications circuits involved in the common cable network of the site.
Kinds of climatic execution of starters UHL5 according to GOST 15150.
It have been used contactors of the company "HANSEN", blocks BDU-4-2, BKZ-3MK and BZ-2.
