Overview
Stefan SB & SBM Series Modular Contactors
Stefan's SB and SBM modular contactors handle the commutation of single-phase and three-phase low-power electrical loads on standard DIN rail enclosures. Built around a compact 1–4 pole body, they switch lighting, heating, ventilation and hot-water circuits without the panel space a conventional contactor demands.
Each unit pairs with auxiliary control, protection and indication accessories, making it suited to remote-control schemes across alternative and load-managed networks — from roller-blind circuits to non-priority load-shedding.
