Overview

The ABB B7S-30-10 is a 3-pole mini contactor from the B7S series, designed for compact control panels in residential, commercial, and industrial applications. Rated for 20 A at 690 V (AC-1) and up to 5.5 kW (AC-3), this AC-operated contactor is optimized for single and three-phase loads where space is limited. The B7S-30-10 features screw terminals for secure wiring, a low-consumption coil (3.5 VA at pull-in and holding) for direct PLC control, and hum-free operation for quiet environments. Integrated protection includes diodes and overvoltage safeguards, while a clear switch position indicator provides immediate operational feedback. Installation flexibility is ensured with DIN rail and wall mounting options. The compact design measures 47.5 mm (1.87 in) wide, 42.2 mm (1.66 in) deep, and 4.5 mm (0.18 in) thick, making it ideal for tight control panel configurations. This contactor is part of ABB’s B7S series, known for reliable motor control in applications ranging from HVAC systems to lighting and automation. Suitable for general use up to 690 V AC, it delivers dependable performance in demanding environments where reliability and space efficiency are critical. The B7S-30-10 also includes one auxiliary contact for additional control signal switching capabilities. This device is specifically engineered for applications where reliability is a must and space is at a premium, offering precise control of single or three-phase loads. Its noiseless and hum-free coil ensures quiet operation, and the integrated protective circuit with diodes and additional overvoltage protection enhances its durability and safety. The switch position indication provides clear operational status, and the integrated possibility for rail or wall mounting offers versatile installation.
