Contactors / Power Modules — Description

Contactors and power modules let you safely switch and measure high-power appliances, from heating boilers to workshop equipment. This category includes DC isolator switches, main breakers and smart energy meters from Qoltec and Sonoff that connect to your smart home hub for real-time consumption tracking. When choosing one, check the rated current, voltage and mounting type — most units fit a standard DIN rail inside the switchboard. 4shop.lv ships these components across Latvia.
