BRA450 Escalator Electro Brake Magnet (Electromagnetic Holding Brake)

 
1. Product Overview
Model BRA450 electromagnetic brake is an exclusive brake magnet designed for escalators, also known as escalator electromagnetic holding brake. It adopts a structure of spring-actuated braking upon power loss and electromagnetic release when energized, integrated with an all-in-one manual release mechanism, serving as the core actuator of the braking system for escalator drive machines.
Equipped with Class F high-temperature resistant insulated coils and an IP55 sealed housing, the unit adapts to long-term continuous operation of both indoor and outdoor commercial escalators, delivering stable 450 N braking force. It perfectly fits the braking systems of drive machines for medium & small public transit escalators and shopping mall moving walkways.
This product is widely supplied to domestic and overseas elevator maintenance contractors, escalator OEM manufacturers, and foreign trade elevator parts distributors. It is compatible with mainstream escalator brands including KONE, Xizi Otis, ThyssenKrupp, Fujitec and SJEC.
During daily escalator operation and maintenance, brakes are safety components with frequent actuation, enduring long-term electromagnetic surges and mechanical wear. Coil aging, plunger jamming, spring fatigue or misadjusted clearance are the primary causes of slow brake response, insufficient braking force, abnormal noise, and even complete safety failure.
The BRA450 electromagnetic brake is widely applied for routine maintenance replacements, braking system overhauls and drive machine assembly retrofitting projects of all brand escalators. It is a frequently purchased spare part for elevator & escalator maintenance service providers, property operation teams and escalator retrofitting contractors worldwide.

2.Core Product Features

• Original Factory Quality： Manufactured by original factory, fully compliant with escalator brake design standards for reliable consistent quality.
• Stable Braking Performance ：Standard 450N braking force with adjustable armature stroke ranging 2.5~3mm, effectively preventing escalator sliding and weak braking faults.

• Power-off Safety Braking ：When the escalator operates normally, the coil is energized and attracted to retract the brake plunger, allowing free movement of the escalator. In case of power cut, emergency stop or fault shutdown, the internal spring instantly pushes the plunger to clamp the brake wheel and lock the steps, preventing escalator sliding or falling, fully complying with national safety standards for escalators.
•  Manual Brake Release for Maintenance ：Pull the external red lever to mechanically push open the brake plunger, releasing the brake manually under power-off status. This function is used for drive machine hand turning, step replacement and fault troubleshooting. The lever must be fully reset after maintenance work.
• Continuous Operation Under Overload Condition： Adopted Class F high-temperature resistant coils with low power consumption current design, eliminating risks of coil burnout from overheating under frequent start-stop scenarios such as shopping malls and transit stations.
•  Universal Replacement Compatibility： Standardized overall dimension and mounting hole positions enable direct replacement of imported and domestic brakes of the same specification, cutting maintenance and retrofitting costs.

• Model Verification：Before installation, verify that the brake model BRA450 matches the on-site escalator drive system, and confirm consistency of rated voltage (AC220V) and mounting dimensions.
• Power Isolation Operation： Cut off the main power supply of the escalator and perform lockout-tagout procedures before installing or replacing the brake to guarantee operational safety.
• Clearance Adjustment ：After installation, adjust the plunger clearance on both sides of the magnet to 1.5 mm and fasten with lock nuts to ensure reliable brake actuation.
• Manual Lever Reset： After installation and adjustment, the red release lever must be reset at an angle of approximately 30~35 degrees before power-on testing.
• Commissioning & Verification： Complete power-on brake release and power-off braking tests after installation and adjustment. Perform manual hand-turning of the drive machine to check smooth rotation and confirm proper brake performance.

• Original Factory Guarantee ：All supplied BRA450 escalator electromagnetic brakes are brand-new genuine original factory products with unique factory serial numbers attached.
• Bulk Foreign Trade Solutions： Available for single-unit retail and full-container bulk export stocking, catering to procurement demands of overseas elevator maintenance companies, spare parts distributors and escalator OEM manufacturers in Southeast Asia, Europe, Australia and other regions.
• After-sales Warranty ：12-month warranty for brand-new complete units; we offer assistance in sorting supporting foreign trade documents including packing lists, commercial invoices and more.
• Packaging & Logistics： Custom shock-resistant and pressure-proof export packaging is adopted, compatible with domestic express delivery, sea freight, air freight and cross-border logistics to reduce the risk of damage during transit.
