ABB B6S-30-10-1.7 Industrial Servo Drive System

ABB B6S-30-10-1.7 is a 3-pole miniature contactor from ABB’s B6S family, driven by a 24 V DC coil with a compact 1.7 W coil power, and it is designed to switch control circuits in automation equipment. It provides 3 normally open (NO) contacts and no normally closed contacts, with screw-terminal wiring for secure connections. The enclosure measures approximately 57.5 mm high, 52.5 mm wide, and 46.7 mm deep, enabling panel mounting in tight control cabinets. Electrical ratings include AC-1 operation up to 20 A at 220/240 V (40 °C) and 16 A at 55 °C; at 380/440 V it remains 20 A (40 °C) / 16 A (55 °C); at 690 V it is 6 A (40 °C) / 6 A (55 °C). For AC-3 operation, it supports 9 A at 230 V and 9 A at 400 V (both 55 °C), 6.5 A at 500 V, and 3.5 A at 690 V (NO configuration). The corresponding AC-3 active power ratings (Pe) are 2.2 kW at 230 V, 4 kW at 400–500 V, and 3 kW at 690 V. This minicontactor is suitable for controlling small to mid-range loads in motor control circuits, conveyors, automation panels, and other industrial switching tasks where a compact, reliable electromechanical device is required.
