We are convinced of the versatility and capabilities of our TOPJOB® S range. But what do users who have to work with it day after day out in the world think of it? In conversation with Managing Director Michael Bieri of Bieri Elektrotechnik AG in Uetendorf, Switzerland.
The TOPJOB® S range includes rail-mounted terminal blocks with operating slots, levers and push-buttons. Which of these terminal blocks exactly do you use?
We use the terminal blocks with operating slots and levers – the latter primarily where measurements have to be performed. In some cases, we even use the measuring disconnect terminals for this purpose, since they allow easy disconnection. More and more, we’re seeing customers wanting a testing option, even for DALI installations.
The terminal blocks are available with different cross-sections. To what extent do you benefit from this variety?
Since we’re not exclusively a controller manufacturer, we need the complete width from the smallest to the largest cross-section. On the high current terminal blocks, we connect up to 160 A with stranded wires and single conductors.
What do you think of push-in termination? As with the 2273 Series Splicing Connector, rigid conductors can also be plugged into TOPJOB® S.
As a control cabinet manufacturer, we work exclusively with screwdrivers and stranded wires on the control cabinet side. But for electricians, being able to plug in rigid conductors without tools is a very good option.
The range also includes double- and triple-deck terminal blocks, as well as various specialty terminal blocks. Which of these solutions are you familiar with?
We’re familiar with the different variants, but we avoid them ourselves as far as possible, since they make the connection situation worse for the electricians. So, when planning the switchgear combination, we always use the normal terminal block to calculate the terminal block space and really only use double-deck terminal blocks in exceptional situations.
