China 8PTSB-1(62) low - voltage switchgear spare parts Manufacturer, Supplier, Factory

At Richge, we specialize in innovative switchgear solutions designed to meet the highest industry standards. Our flagship product, the switchgear limit nail, is engineered to enhance the reliability and safety of electrical systems. This critical component ensures precise alignment and prevents mechanical failures by limiting the movement of switchgear elements.

KQ2C push-in caps are dedicated tube plugs for SOLH KQ2 one-touch pneumatic fittings, engineered as drop-in alternatives to SMC KQ2C. Featuring tool-free insertion, the caps lock into unused push-in ports to achieve reliable sealing for both vacuum and compressed air circuits. Constructed with PBT body and NBR sealing ring, they cover sizes Φ2 through Φ16. Widely used for equipment commissioning, manifold spare port closure and temporary circuit isolation in automation machinery, valve islands and vacuum systems.

The GN22-12 (C) (D)series indoor high-voltage disconnecting switch is designed for power systems with a rated voltage of 12kV and a frequency of 50Hz. This device is mainly used for opening and closing circuits in the power system under no-load conditions. With high current withstand capabilities, it is ideal for applications requiring high security and frequent operations. The device can be configured to meet various environmental needs. This product is a high-current isolating switch with a three-phase common bottom knife structure. It adopts a mechanical locking prototype with a two-step action of closing and contacting, achieving wear-free contact, small operating force, high contact pressure, and good dynamic thermal stability.

Richge is a manufacturer of Electric Interlock Mechanisms in China, specializing in sophisticated solutions designed to enhance the safety and reliability of electrical systems. Our electric interlock mechanisms are engineered to provide precise control and prevent unauthorized or unsafe operations in various switchgear applications.

SOLH MD multi-position free-mount compact cylinder is equipped with tapped mounting holes on six sides of the block body for bracket-free installation at any angle, 30%~50% thinner than standard round cylinders to fit narrow, high-density equipment layout. Five sub-models cover all working modes: standard single-rod double acting MD, single-rod single acting MSD (spring extend) / MTD (spring retract), anti-torsion double-rod MDD, and stroke-adjustable double-rod MDJ. Bore sizes range from 6 to 32 mm with standard strokes 5~60 mm. Each unit comes with built-in front rubber buffer and dual side slots for magnetic sensors; suffix-S stands for integrated permanent magnet compatible with CMSH/DMSH reed switches. The piston rod adopts integrated self-lubricating bushing for oil-free smooth operation. Double-rod variants eliminate lateral deflection from offset loads, while MDJ features rear adjustment screw for flexible stroke fine-tuning. Widely applied to light-duty clamping, ejecting, crimping and precise positioning of miniature jigs in 3C, semiconductor and general small automation machinery.

interlocking mechanism for switchgear Switchgear Interlocking Mechanism - Product Details and Applications The Switchgear Interlocking Mechanism is a critical safety and operational component designed to ensure the secure and coordinated operation of electrical switchgear. This mechanism prevents inadvertent or unauthorized operation of switches, breakers, and other electrical equipment by establishing a series of interlocking conditions. Typically installed within the switchgear panel, the interlocking mechanism is activated during specific operational sequences to prevent the opening or closing of certain parts unless predefined conditions are met.
