Electrical interlocking is a mechanism of electrical controls and devices designed to ensure the safe and orderly operation of electrical circuits, machinery, or equipment by preventing certain actions or conditions unless specific prerequisites are met.

Most interlock devices for electrical systems employ a mechanical device to manage the movement of circuit breakers. Some also allow for the use of padlocks to prevent someone from accidentally activating the main power system without authorization.

Mar 24, 2025 · Mechanical interlocks are physical and direct, while electrical interlocks use electricity to sense, control, and prevent actions. Why Choose an Electrical Interlocking System?

Aug 28, 2021 · Electrical interlocking. In this type of interlocking, there won’t be any manual operation all the interlocking processes will be carried out electrically and automatically. This interlock is done only by an electrical circuit and there won’t be any mechanical means for this type of interlocking.

Nov 7, 2009 · A mechanical interlock is sometimes needed to prevent that two contactors (e.g. a FWD and a REV) are actuated simultaneously. That can happen in certain installations (overhead cranes) when forces from a sudden deceleration like hitting a …

Apr 6, 2025 · These types of interlocks can be mechanical, electrical, or logic interlocks. A mechanical interlock is an interlock that is physically connected to another device to prevent unintended actions. A simple example of a mechanical …

Dec 16, 2024 · Electrical interlocking uses auxiliary contacts and relays, mechanical interlocking employs physical locks, keys, and cam-operated devices, while logical interlocking is implemented using PLCs (Programmable Logic Controllers) or SCADA logic.

Nov 27, 2014 · Mechanical interlock is physical prevention of concurrent operation. It is commonly implemented by physically preventing the contacts of one of two contactors from changing to the energized state, even if the defeated contactor's coil is energized.

Jan 3, 2025 · In general, the two major interlocking techniques used for hazard prevention are normally closed contact systems and electrically interlocked systems: mechanical interlocking and electrical interlocking.
