It provides remote electrical operation of the breaker — opening, closing, and reset — from a control panel or PLC output, eliminating the need for an operator to be at the panel door. Control voltage is 230 V AC, rated for both 50 Hz and 60 Hz supplies, with an initial operating range of 195.5 V and a final rated value of 253 V. Maximum operating frequency is 251 operations per hour. Mounting is by screw fixing in any position — no DIN-rail clip on this accessory. The mechanism measures 236 mm deep, 148 mm wide, and 224 mm high, with zero clearance required on all sides (upwards, forwards, backwards, downwards, and at the side).

Frequently asked questions
Where can I buy 3RV1946-3AP0 and how do I get a price?
This part is sourced to order against an RFQ through our independent distribution network. Submit a request for quote (RFQ) and we will confirm current availability and pricing at that time — no stock count or price is published here because supply is variable on a phased-out line.
What is 3RV1946-3AP0's listed depth?
The depth is 236 mm. Combined with the 148 mm width and 224 mm height, and zero clearance required on all sides, this mechanism needs a fairly deep enclosure — account for that when retrofitting into an existing panel.
