Product Introduction

Overview
Using TXCPS as the main switch, combined with mechanical and electrical interlocking accessories, a star delta pressure reducing starter TXCPSJ is formed, which is suitable for reversible or bidirectional control and protection of electric motors. The main circuit parameters and accessory modules are of the same basic type.

The meanings of each part of the product model are as follows

Circuit diagram for reversible operation control of electric motor

Secondary power supply	power protection	power protection	Voltage reduction start and alarm signal					Delay conversion	Full pressure operation and running signal	stop signal
			Local and remote manual control in two locations	short circuit	fault	start	Voltage reduction delay

Note:
① This diagram is applicable for single motor (45KW and below) star delta pressure reducing starting, which adopts local and remote manual control.
② The shape of the star delta pressure reducing starter is determined by the engineering design, as detailed on pages 9-15 of this atlas.
③ External introduction The stop button can be installed on the surface of the box or wall.
