Product Introduction
This collection features genuine-equivalent NOV TDS electrical parts, spanning circuit breakers (CB-16AT, E3 series 1600AF/800AF), rectifiers, VFD inverter modules, fuses, contact blocks, power supplies, metering devices, and control PCBs. Each part is manufactured to replicate OEM form, fit, and function, with strict quality testing for high-amperage, high-voltage drilling environments. Covered part families include CB thermal-magnetic breakers, UVR (undervoltage release) coils, auxiliary contacts, DC power supplies, rectifier fan PCBs, and Profibus communication modules—all tailored for TDS drilling top drives.
Functional Capabilities
- Power Distribution & Protection: Circuit breakers and fuses deliver overcurrent, short-circuit, and undervoltage protection (6kIC–75kIC interrupt ratings), safeguarding TDS power trains and sensitive control electronics
- Motor Control & Variable Speed Regulation: VFD/inverter components (500KW drive modules, precharge boards) enable precise top-drive motor speed control, optimizing drilling torque and efficiency
- Voltage Conversion & Rectification: 3-phase rectifiers (2700A, 690V) and transformers (2KVA, 500VA, 150VA) convert AC to DC power and regulate voltage for TDS control circuits
- System Monitoring & Metering: Digital meters (KW, KVAR, AAC) and hour meters track real-time power usage, runtime, and operational performance for preventive maintenance
- Ground Fault & Sync Detection: Ground detection modules and sync check cards ensure safe rig operation, preventing electrical hazards and phase misalignment
Structural & Design Features
- DIN Rail & Panel Mounting: Compact, industry-standard mounting designs for easy installation in TDS control cubicles (600MM fixed breaker enclosures, vertical stabilizer kits for 3200A breakers)
- Lockout/Tagout Compatibility: Padlock covers and operator buttons enhance OSHA-compliant lockout procedures during maintenance
- Modular PCB Design: Plug-and-play control boards (rectifier fan power supply, motor control units) reduce repair time and simplify component replacement
- High-Current Termination: Heavy-duty terminal blocks (30-pin, 2-pin) support 26–10AWG wiring, handling maximum current loads without overheating
- Environmental Sealing: Rugged construction resists oilfield dust, moisture, and mechanical vibration, extending service life in extreme conditions
Applicable Operating Environments
These electrical parts are engineered foronshore and offshore drilling rigs operating in extreme industrial conditions, with certified performance for:
- Voltage ranges: 24VDC–690VAC, 1000VDC
- Current ratings: 0.6A–3200A
- Temperature ranges: -40°C to 85°C (industrial operating threshold)
- High-vibration, high-dust oilfield environments
- Fixed and mobile TDS top-drive systems (1600A generator/feeder cubicle configurations)
Preventive Maintenance Recommendations
- Regular Inspection Schedule: Conduct visual and electrical testing every 3 months to check for loose terminals, burnt contacts, and fuse degradation; document meter readings and breaker trip history
- Component Replacement Intervals: Replace wear-prone parts (fuses, contact blocks, surge suppressors) annually or after 2000 operating hours; replace circuit breakers and rectifiers every 5 years or post-fault
- Environmental Protection: Keep control cubicles sealed and dust-free; apply dielectric grease to terminal connections to prevent corrosion in humid offshore environments
- Calibration Checks: Recalibrate power meters and voltage transducers every 6 months to ensure accurate monitoring and compliance with industrial standards
- Spare Inventory Management: Stock critical fast-moving parts (fuses, CB auxiliary contacts, relays) on-site to minimize downtime during emergency repairs

Field Troubleshooting: Real-World Failure Cases
Case 1: CB-16AT Circuit Breaker Tripping Without Load
A land drilling rig experienced repeated nuisance tripping of the 16AT 2P circuit breaker (part 10040321-001) in the incomer module. Diagnosis revealed a faulty undervoltage release (UVR) coil and worn auxiliary contacts. Replacing the UVR coil (10633696-001) and auxiliary contact block (10633704-001) restored stable operation, eliminating unplanned tripping and 8+ hours of downtime.
Case 2: VFD Inverter Communication Failure
An offshore rig’s 500KW VFD inverter (part 10909468-001) lost Profibus communication, disabling top-drive speed control. Technicians identified a faulty Profibus module (10044500-001) and fiber optic module (10044530-001). Swapping the damaged control boards restored communication, resuming drilling operations within 4 hours.
Case 3: Generator Cubicle Fuse Bank Failure
A 1600A generator cubicle experienced a 30A fuse (10041043-042) blowout due to overcurrent. The fuse holder (10067465-001) showed signs of overheating, indicating a loose terminal connection. Tightening terminals and replacing the fuse bank and holder prevented repeat failures and avoided a full system shutdown.
