PRAGADA MUKESH Brass Castle Locks are engineered safety devices designed to provide secure key interlocking mechanisms in electrical switchgear. These locks feature a unique safety mechanism where the key remains trapped in the locked position while the switch is 'ON' (closed) and is only released when the switch is shifted to the 'OFF' (open/isolated) position. Ideal for applications in high-voltage (HV) substations, ring main units (RMU), and compatible with Siemens MCCB kits including models like 3VT and 3VA, these locks facilitate error-proof maintenance by enforcing a strict operational sequence. Available in various types such as FS, Q, and specialized interlock models for panel doors and access, the Brass Castle Locks incorporate a square spigot or similar mechanical connection for seamless integration with switches. Built to endure harsh environments, they ensure maximum safety and operational reliability in critical electrical infrastructure settings.

Yes, these locks are primarily designed for 3VT and 3VA but can be compatible with other Siemens MCCB models with similar mechanical fittings.
The locks typically use a square spigot or equivalent mechanical interfaces to ensure secure connection with switches.
Yes, constructed from durable brass, these locks are well suited for harsh environments including outdoor high-voltage substations.
Yes, the design ensures the key is trapped while the switch is on and only releases it when the switch is safely turned off, preventing accidental switch operation.
Minimal maintenance is needed; periodic inspection and lubrication are recommended for optimal mechanical performance.
