Mechanical interlock for the FIX version, current rating A, between three EPLH-FWB2A circuit breakers/disconnectors. 004697209

What is it and how does it work

A mechanical lock designed for the FIX version, providing a physical linkage for three EPLH-FWB2A circuit breakers or disconnectors. Product with catalog number 004697209 protects the system against accidental disconnection, which is particularly important in installations requiring high reliability – e.g., in emergency power systems or industrial switchgear.

Benefits and applications

• Uniform protection – locks all three circuit breakers simultaneously, eliminating the risk of unintentional disconnection of any single unit.
• Easy operation – the locking and unlocking mechanism operates manually, without the need for additional tools, speeding up maintenance work.
• Compatibility – dedicated exclusively to the EPLH-FWB2A series, so the installer does not need to worry about matching dimensions or electrical parameters.
• Robust construction – the housing weighs 4.9 kg, ensuring stability at the installation point while remaining lightweight enough for transport (total package weight ≈ 5 kg).
• Use in critical circuits – ideal for motor control systems, emergency power supplies, and any application where three circuit breakers must operate synchronously.

Installation and compliance

Installation is performed on a standard mounting rail; the lock is screwed to the switchgear frame in the same manner as other components from the same catalog group. Thanks to its simple locking mechanism, it can be installed within a few minutes, and unlocking after completion of work requires only turning the lever. The product meets customs tariff requirements 85389099, confirming its classification as a protective component in electrical installations.
