Openers & Closers 51B10 Electric Strike 6-14V AC/DC Fail-Secure With Switch EN 14846

Product Overview

The Elektrozaczep Openers & Closers 6-14V AC/DC with switch (51B10) is a fail-secure electric strike designed for controlled access on internal doors. With holding force of 4,800N and certified according to EN 14846:2008, it is used in commercial and residential environments where secure entry and operational cycles are required. The device operates with voltage from 6 to 14V AC/DC, and works reliably in temperature ranges from -25°C up to +70°C.

The integrated switch feature distinguishes the 51B10 from generic electric strikes, as it allows the strike to be mechanically locked when power is disconnected, eliminating risk of unauthorized access during power outages. This is especially relevant for property managers and security contractors responsible for entry systems in office buildings, apartments, and secured warehouses, who require compliance to EN 14846 and robust mechanical fail-secure protection.
