Part #70130077 is a PKZMO-6.3T motor protection switch engineered specifically for Bullmer automatic cutting machines. This critical electrical component safeguards drive motors—such as those for the cutting head, conveyor, or sharpener—against overload, phase failure, and excessive current draw. By monitoring electrical conditions in real-time and interrupting power during fault states, it prevents motor burnout, reduces downtime, and ensures the long-term reliability of the cutter’s core motion systems in industrial production environments.

• Precise Motor Protection: Provides reliable thermal and magnetic overload tripping calibrated for Bullmer cutter motors, preventing damage from jams, excessive load, or electrical faults.
• Phase Failure Prevention: Detects phase loss or imbalance in three-phase systems, a common cause of motor failure, and disconnects power to avoid costly repairs.
• Easy Integration & Setting: Designed for straightforward installation in Bullmer control cabinets with adjustable current settings to match specific motor ratings.
• Durable Industrial Design: Built to withstand electrical noise, vibration, and temperature variations typical in textile and material cutting workshops.
• Safety & Compliance: Helps meet industrial safety standards by providing dedicated motor protection, reducing fire risks and improving overall system safety.

• Part Number: 70130077
• Device Model: PKZMO-6.3T Motor Protection Switch
• Rated Current: 6.3A (adjustable within range)
• Application: Protection of drive motors in Bullmer auto cutters (main cutter, conveyor, sharpener, etc.)
