HIRD-BROWN Product Lines We Repair
Our engineers are trained on the full HIRD-BROWN product range. Below are the major product families we service.
Hird-Brown Relay Logic Assemblies
Hardwired relay-based control systems used for motor sequencing and industrial automation. Common issues include contact erosion, coil burnout, mechanical jams in relay stacks, and electromagnetic chatter affecting switching precision.
Motor Control Centres (MCC)
Integrated electrical distribution and motor starting units for industrial applications. Frequent faults include contactor failure, overload relay tripping, bus bar oxidation, and cable termination overheating in humid Indian factory environments.
AC Motor Starters
Electromechanical motor starting equipment for variable load applications in textile and sugar mills. Common repair issues include contactor wear, thermal overload calibration drift, and starter coil insulation breakdown.
Switchgear and Distribution Panels
Industrial-grade electrical switchgear for main distribution and feeder control in plants. Typical faults include switch mechanism stiffness, internal arc marking, fuse holder corrosion, and voltage reference instability.
Thermal Overload Relays
Bimetallic and electronic thermal protection devices for motor circuits. Repair needs include calibration reset, bi-metal element replacement, and adjustment of trip point settings to match motor nameplate ratings.

Common HIRD-BROWN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HIRD-BROWN equipment arriving at our workshop.
- ✓Relay contact erosion and sticking — High inrush currents in motor starting circuits cause arc damage and material transfer on Hird-Brown relay contacts, leading to incomplete switching and intermittent circuit interruption in legacy control systems.
- ✓Motor contactor coil burnout — Sustained overvoltage from sudden load disconnection, moisture ingress in humid Indian mill environments, or extended holding current draw in Hird-Brown contactors weakens coil insulation until complete failure occurs.
- ✓Thermal overload relay calibration drift — Continuous thermal cycling in plants operating 24/7 shifts causes bimetallic elements in Hird-Brown overload relays to lose accuracy, resulting in nuisance trips or inadequate motor protection at higher ambient temperatures.
- ✓Bus bar oxidation and connection resistance — Tropical humidity and industrial dust in Indian factories promote rapid oxidation of copper bus bars in Hird-Brown MCCs, increasing contact resistance and generating localized heating at connection points.
- ✓Mechanical jam in relay armature stack — Dust accumulation, corrosion products, or bearing wear in multi-relay assemblies found in Hird-Brown systems prevents free movement of armatures, causing failure to energise or release circuits.
- ✓Switchgear mechanism binding and sluggish operation — Years of operation in Indian industrial facilities cause lubricant breakdown, rust formation on switch mechanisms in Hird-Brown switchgear, and mechanical binding that extends switching time and increases arc duration.

Frequently Asked Questions — HIRD-BROWN Repairs
Do you repair Hird-Brown equipment anywhere in India?+
Yes. Synchronics repairs the full Hird-Brown industrial control range — relay logic systems, motor control centres, starters, and switchgear. We provide PAN India pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all major cities. All repairs are processed at our main facility in Vadodara, Gujarat with 24-48 hour turnaround on standard faults.
What is the typical turnaround time for Hird-Brown motor control centre repair?+
Standard MCC repairs typically require 5-7 working days including complete electrical testing, contactor replacement if needed, and bus bar inspection. Emergency repairs for production-critical systems can be expedited to 24-48 hours. Synchronics maintains stock of common Hird-Brown replacement contactors, overload relays, and starter components to minimise downtime.
Can Synchronics repair vintage Hird-Brown relay logic systems no longer manufactured?+
Absolutely. Our engineers specialise in restoring legacy Hird-Brown relay assemblies from the 1950s onwards. We have the expertise to wind replacement coils, fabricate contact assemblies, and recalibrate thermal elements to match original specifications. We provide full technical documentation and can advise on modernisation options if preferred.
What is your warranty on Hird-Brown relay and contactor repairs?+
All repaired Hird-Brown components carry a 12-month functional warranty covering parts and labour. We provide detailed test reports showing all electrical parameters and switching performance. If equipment fails within warranty, we repair or replace at no charge, plus cover any standard shipping costs.
Do you offer preventive maintenance for Hird-Brown switchgear in Indian mills?+
Yes. Synchronics offers planned maintenance contracts for Hird-Brown switchgear and motor control systems. We perform on-site inspections, thermal imaging to detect overheating connections, contact resistance measurement, and lubrication of mechanisms. This predictive approach helps textile mills, sugar plants, and heavy engineering facilities avoid unplanned shutdowns.
How do I send my HIRD-BROWN 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 HIRD-BROWN 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 HIRD-BROWN 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 HIRD-BROWN 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.
