WLDS1 DC fast circuit breaker is mainly used for short circuit and overload protection of main circuit of traction power supply system of subway, light rail, tram, industrial and mining electric locomotive with rated voltage DC1800V and below, rated current 4000A and below, and can also be used for classification protection of semiconductor rectifier devices in industrial field. WLDS1 is a single-pole bidirectional DC fast circuit breaker, which adopts electromagnetic control and natural cooling.

QDS8 DC high-speed circuit breaker is mainly used for short-circuit and overload protection of the main circuit of the traction system of subway, light rail, tram, industrial and mining electric locomotive with rated voltage DC1800V and below and rated current 1250A. It can also be used for classification protection of semiconductor rectifier devices in the industrial field. QDS8 is a single-pole bidirectional DC high-speed circuit breaker with electromagnetic control.

WLCZ1-800 type DC electromagnetic contactor is suitable for industrial and mining electric locomotives, subways, light rails, trains and EMU electric locomotives, ground traction stations, line switching devices and DC charging equipment with rated voltage DC1800V or less and rated current 800A or less. It is a nonpolar contactor used as a tap conversion control contactor for main circuit unit control and auxiliary circuits.

WLCZ1-250 type DC electromagnetic contactor is suitable for charging circuit and DC auxiliary power supply control with rated voltage of DC900V and below and rated agreed heating current of 250A and below.

circuit and reclosing detection circuit are polarity contactors.
