The ABB B7S-40-00 Miniature Contactor is a compact 4-pole contactor with screw terminals. They are ideal for applications where reliability is essential and space is high. Small contactors are used in residential, commercial building, and industrial applications to control single- or three-phase loads of 5.5kW (AC-3) or 20A/690 V (AC-1) or control signal switching. Due to the low coil consumption, the device can be controlled directly by the PLC. Further features are noise-free and noise-free coils, integrated protection circuitry with diodes and additional overvoltage protection, switching position indication and the combined possibility of railway or wall mounting. auxiliary contacts,
