BO-SHERREL CO Product Lines We Repair
Our engineers are trained on the full BO-SHERREL CO product range. Below are the major product families we service.
Electromagnetic Motor Starters
Heavy-duty NEMA-rated magnetic starters for motors up to 500 HP. Common failures include burnt coils from voltage surges, stuck armatures due to dust infiltration, and contact erosion from frequent switching cycles in textile and cement plants.
Industrial Contactors and Relays
DC and AC contactors with auxiliary relay blocks for process control. Typical issues include pole chatter, contact pitting from inductive loads, and coil burnout from inadequate varistors in motor control centers.
Overload Thermal Relays
Bimetallic and electronic overload protection devices for motor branch circuits. Failures often stem from calibration drift, bimetallic element fatigue, and nuisance trips from harmonic current in VFD-driven motors.
Control Transformers and Reactors
Step-down and isolation transformers for control circuits in legacy plants. Common faults include winding short-circuits from moisture ingress, core saturation under harmonic loads, and insulation degradation in high-vibration mill environments.
Soft-Start and Starter Enclosures
Enclosed combination starters with disconnects and fuses for Indian plant floor standards. Issues include contactor chatter under low-voltage conditions, thermal relay nuisance trips, and weathering of outdoor enclosure seals.

Common BO-SHERREL CO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BO-SHERREL CO equipment arriving at our workshop.
- ✓Burnt electromagnet coil in motor starter — Bo-Sherrel starters often experience coil burnout due to sustained over-voltage from grid fluctuations (common in Indian industrial zones), inadequate surge suppression, or incomplete contact closure causing continuous coil current draw.
- ✓Stuck armature preventing starter energization — Bo-Sherrel electromagnetic starters are prone to armature stiction in dusty textile mills, cement plants, and foundries. Fine dust particles settle in the air gap, and moisture creates a caked layer that prevents normal armature travel.
- ✓Contact erosion and arcing in contactors — Bo-Sherrel contactors fail when switching inductive loads (motors, inductors) without adequate arc suppression. High inrush currents cause contact material erosion, leading to pitting, increased contact resistance, and eventual failure to maintain connection.
- ✓Thermal relay nuisance tripping — Bo-Sherrel bimetallic overload relays calibrate drift over time, especially in hot mill environments (40-50°C ambient common in Indian plants). Harmonic currents from VFD-driven motors also cause disproportionate heating, leading to false trips.
- ✓Control transformer winding short-circuit — Bo-Sherrel control transformers suffer winding insulation breakdown from moisture ingress in humid Indian climates, physical vibration damage in mill environments, and voltage transients that stress insulation between primary and secondary windings.
- ✓Contactor chatter and intermittent operation — Bo-Sherrel contactors chatter when coil voltage drops below pull-in threshold due to weak grid, long cable runs to motor control center, or voltage sag events common during plant start-up. Mechanical wear also reduces spring tension needed for stable closure.

Frequently Asked Questions — BO-SHERREL CO Repairs
Do you repair Bo-Sherrel Co. equipment anywhere in India?+
Yes. Synchronics repairs the full Bo-Sherrel Co. product range — electromagnetic starters, contactors, overload relays, control transformers, and soft-start enclosures. We offer PAN-India door pickup and drop from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and all major industrial cities. All repairs are completed at our ISO-certified Vadodara facility in Gujarat.
What makes Bo-Sherrel electromagnetic starters fail in Indian textile mills?+
Bo-Sherrel starters in Indian textile mills fail primarily due to dust infiltration causing armature stiction, voltage surges from unstable grid supply causing coil burnout, and thermal relay drift from sustained high ambient temperatures (40-50°C in many mills). Synchronics specializes in diagnosing and repairing these mill-specific faults, recalibrating relays, and installing surge protection to extend equipment life.
Can you recalibrate Bo-Sherrel overload thermal relays?+
Yes. Synchronics recalibrates Bo-Sherrel bimetallic overload relays on precision test benches to match actual motor nameplate current and ambient temperature. If relays are aged or if your plant has VFD-driven motors causing nuisance trips, we recommend upgrading to electronic overload relays with true RMS sensing — we source and retrofit these into your existing Bo-Sherrel starter enclosures.
Do you source genuine Bo-Sherrel replacement parts or equivalent components?+
Synchronics sources equivalent industrial-grade replacement parts for Bo-Sherrel starters, contactors, and relays — coils, contacts, overload elements, transformers, and enclosures from certified suppliers. For critical OEM applications, we can special-order genuine Bo-Sherrel components through North American distributors. We document all parts used and provide warranty on repair work.
How long does a typical Bo-Sherrel starter repair take?+
Most Bo-Sherrel electromagnetic starter repairs — coil replacement, armature cleaning, contact resurfacing, relay recalibration — are completed within 3-5 business days at our Vadodara facility. Urgent mill shutdowns can be prioritized. We offer same-city pickup and delivery in major industrial centers and use insured courier for remote locations. We always provide detailed fault reports and test certificates.
How do I send my BO-SHERREL CO unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a BO-SHERREL CO drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on BO-SHERREL CO repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your BO-SHERREL CO unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
