Electronics Manager

Job Summary

An Electronics Manager for Circuit Breaker Trip Units oversees the design, development, and testing of the "intelligent" core of a LV switchgear and it’s accessories. These electronic trip units (ETUs) are microprocessor-based systems that detect electrical faults—such as overloads, short circuits, and ground faults—and trigger the mechanical opening of the breaker.

Core Responsibilities

- Product Development: Lead the design of microprocessor-controlled trip units for low-voltage power circuit breakers.

- Firmware & Protection Logic: Oversee the development of protection algorithms, including Long-time (L), Short-time (S), Instantaneous (I), and Ground-fault (G) pickup and delay settings.

- Metering & Connectivity: Manage the integration of advanced features like real-time energy metering, event logging, and communication protocols such as Modbus, Profibus, or Ethernet.

- Regulatory Compliance: Ensure all electronic components and software meet industry standards like UL 489, IEC 60947-2, and EMC/EMI requirements.

- Testing & Calibration: Supervise primary and secondary injection testing to verify the accuracy of time-current trip curves and coordination.

- Project Lifecycle: Manage projects from initial concept through factory acceptance tests (FAT) and field release.

- Technical Leadership: Direct the development of microprocessor-based trip units, ensuring high precision in Long-time, Short-time, Instantaneous, and Ground-fault (LSIG) protection algorithms.

- Product Strategy: Define product roadmaps for smart breakers, integrating IoT connectivity (Modbus, Ethernet), energy metering, and advanced diagnostics.

- Compliance & Standards: Ensure all designs comply with UL 489, IEC 60947-2, and EMC/EMI requirements for industrial environments.

- Verification & Testing: Oversee primary and secondary injection testing,



time-current curve validation, and reliability testing (HALT/HASS).

- Team Management: Mentor a team of 5–10 engineers, managing project budgets, timelines, and vendor relationships for components like Current Transformers (CTs) and PCBAs.

Job Requirements & Qualifications

- Technical Expertise: Knowledge of low-voltage switchgear, circuit breaker fundamentals, and electrical distribution systems.

- Electronics Knowledge: Understanding of microprocessor-based controls and solid-state sensors.

- Software Familiarity: Experience with configuration software used for setting and calibrating ETUs.

- Testing Experience: Capability to perform secondary injection tests for troubleshooting and maintenance.

Key Technical Skills

- Hardware Design: Deep knowledge of analog and digital circuit design, including current transformers (CTs) for sensing and solid-state circuitry for tripping.

- Embedded Systems: Proficiency in C/C++ programming for microcontrollers and real-time operating systems (RTOS) used in safety-critical applications.

- Sensing Technology: Expertise in True RMS measurement techniques to ensure trip units are unaffected by harmonics or ambient temperature.

- Simulation Tools: Ability to use tools like MATLAB or SPICE for circuit simulation and Altium or Cadence or Eagle for PCB design.

Required Qualifications

- Education: Bachelor’s or Master’s degree in Electrical Engineering, Electronics, or a related field.

- Qualified Experience: 8–12+ years in LV switchgear, protection relays, or power electronics, with at least 3–5 years in a leadership or managerial role.

- Safety Certifications: Familiarity with high-voltage safety practices and standards like NFPA 70 or OSHA.

Key Skills

- Understanding time-current curves and coordinating protection devices.

- Troubleshooting electronic control modules.

- Programming protective settings.

- Interpreting fault diagnostics.
