Overview

The ABB LS45P52B11 is a 40mm adjustable limit switch with a 22mm stainless steel roller actuator, designed for low-voltage control applications. Manufactured by ABB - Electrification, this switch features a fast clip mounting system for 35mm DIN rails (EN 60715) and supports installation in any position. It offers bi-directional cylinder-lift terminal connections for IEC 2.5-25mm² cables or 10mm² busbars, with a tightening torque of 2.8 Nm. The 2-pole configuration measures 85mm (H) x 69mm (D) x 35mm (W). Withdrawal from the busbar is tool-free from the bottom (not for 125A models). Ideal for control panels and automation systems requiring precise adjustment and robust construction.
