12-channel multifunctional actuatorBX-MFB12
The BX-MFB12 is a 12-channel DIN-rail-mounted multifunctional actuator for independent switching of loads by means of closing contacts. The 230 V ac switching output can be controlled by the push buttons on the front.
A green LED indicates the status of the channel.
It features 16 A bistable relays with contacts connected directly to the terminals, without phase sharing.
The screw terminals can accept cable sections up to 5 mm2. The relays used can withstand an inrush current of up to 320 A in the first 2 ms, making them particularly suitable for controlling inductive loads such as fluorescent or neon lamps.
