Kelco L Series 25mm Side Entry Poly Level Switch

The Kelco L-H-25B is a heavy-duty, side-entry liquid level switch designed for reliable tank and process control in industrial, agricultural, and chemical applications. Built from glass-reinforced polypropylene with a corrosion-resistant seal-less magnetic drive, it delivers long service life even in harsh environments.

Featuring a 500V AC, 15A SPDT microswitch, the L-H model is suitable for general control circuits, including direct pump motor control up to 0.5HP at 240V AC, or for use with contactors and relays for larger loads. A built-in manual override allows for easy testing, commissioning, and manual pump activation.

The modular construction separates the electrical and mechanical components for easy servicing, and its IP67-rated housing ensures dependable operation in outdoor or washdown environments. The L Series is also available in a low-voltage L-RL model for PLC and telemetry use, including hazardous area applications when isolated via an intrinsically safe barrier.
