A Unica System+ prewired modular power unit fitted with a two-pole residual current breaker, rated 16 A at 250 V. It is a made-up assembly rather than a loose device: the unit arrives wired, in a rectangular aluminium housing, with quick-connect (Mini-Wieland) power connections at each end so several modular units can be chained onto one and the same power circuit. It is designed for pole, post and desk mounting, which is where this style of protected power take-off belongs — office furniture, benches, workstations and similar installations where the earth-fault protection has to travel with the outlet. THIS ITEM IS THE ANTHRACITE VERSION, a dark grey. It is otherwise identical to the INS44216, which is the white version; colour is the only difference between the two. Supplied by cBallast on quote-to-invoice terms; lead time and freight are quoted per RFQ against the destination Incoterm.
