Overview

The ABB K6S-40E-1.7 is a 4-pole mini contactor relay designed for compact control applications requiring reliable switching of low-power signals. This AC-operated device features four normally open (N.O.) contacts and screw terminals, rated for 4 A at 240 V AC (AC-15). With a coil consumption of just 3.5 VA at both pull-in and holding, it can be directly controlled by PLCs, eliminating the need for additional interfacing components and reducing system complexity. Engineered for space-constrained environments, the K6S-40E-1.7 measures 47.5 mm x 42.2 mm x 4.5 mm, making it ideal for tight panel layouts in residential, commercial, and industrial installations. The integrated protective circuit includes diodes and overvoltage protection to safeguard against electrical transients, ensuring long-term reliability. The hum-free coil operation eliminates acoustic noise, a critical feature for noise-sensitive applications. Installation flexibility is enhanced with integrated DIN rail and wall mounting options, simplifying panel assembly and maintenance. The clear switch position indicator provides immediate visual feedback on the relay's status. The K6S series supports add-on auxiliary contact blocks for front or side mounting, allowing for scalable control logic expansion as system requirements evolve. Compliant with IEC/EN 60947-5-1 for mechanically linked contacts, this relay is rated for 4 A at 220-240 V AC and is manufactured in the US. The K6S-40E-1.7 is part of ABB's Electrification division's K mini contactor relay family, specifically designed for control signal switching up to 3 A / 400 V (AC-15).
