Locks for electrical panels

OMR switchboard locks are designed to provide security, functionality and strength in technical cabinets, distribution boards and industrial plants. Ideal for LV, MV and HV applications, they are compatible with operator panels, HMIs, control cabinets and technical compartments. Available in 1/4-turn, cam or swing-handle versions, they offer extensive locking (deadbolt, espagnolette, latch) and keying (KA, KD, passe-partout) options. Materials range from stainless steel to die-cast metal, with chrome, galvanized or black finishes. Solutions include cipher keys or standard shapes (triangular, square, screwdriver), compatibility with varying door thicknesses, and plate-cylinder or pin tumbler mechanisms. Perfect for installation on metal and aluminum, they meet the needs of professional electrical designers and builders.

The electrical panel is the heart of any system, and it is important to protect its components with electrical panel locks so as to prevent unauthorized access or unintentional damage.

OMR Serrature manufactures in Italy locks for distribution, automation and on-board switchboards, LV (low voltage), MV (medium voltage) and HV (high voltage) industrial switchboards. We also recall locks for switchboards with microswitches, HMI (Human Machine Interface) device interfaces, operator panels and control cabinets of various types, elevator and air conditioning system controls, servers, cabins, technical compartments, water and gas meter boxes, and even machinery doors, public controls related to traffic lights and street lighting.

For electrical panels and similar elements, the company generally offers knobs, ¼-turn locks made of zinc alloy, ¼-turn locks with special keys, padlockable revolving handles, T-handle locks, selectors, budget locks, mechanical interlocking systems for electrical cabinets, and metal or plastic knob locks.

Approfondimento su: Locks for electrical panels

To choose the most suitable lock for an electrical panel, it is essential to evaluate the hole diameter (13 to 25 mm), the type of locking required (cam, espagnolette, multi-point cams), key extraction positions (in closed/open or closed position only), and the desired key code (KA, KD, or passe-partout). The choice of shape (triangular, hexagonal, screwdriver) affects security and compatibility with industry standards. For critical or outdoor environments, durable materials such as stainless steel or galvanized finishes are recommended. Systems can be installed on metal/aluminum using nuts, horseshoe clips or screws.

What are cabinet locks used for?

Panelboard locks are used to protect the internal components of technical cabinets and plants from unauthorized or accidental access. They are used in industrial environments to provide operational security on automation, distribution and control panels.

Which type of key is best suited for industrial applications?

It depends on the level of security required: non-reversible or tubular flat keys offer more protection than standard shapes (triangular, screwdriver). For public or multisite installations, keyed alike (KA) or passkey is useful.

How to choose the correct lock rotation?

Rotation depends on door position and locking mechanism: some locks offer 90°, 160° or 180° rotations, with specific options for left or right hand. It is important to check this at the design stage to ensure that the frame opens correctly.
