Industrial Safety Solution – Honeywell 10310/3/1 | Earth Leakage Detector Series
Where This Product Is Used
The Honeywell 10310/3/1 Earth Leakage Detector is engineered for mission-critical electrical safety applications across heavy industry. Engineers and system integrators specify this module in environments where undetected ground faults can cause equipment damage, production downtime, or personnel injury.
- Motor Control Centers (MCC): Continuous ground fault monitoring on 3-phase motor feeders to prevent insulation breakdown and motor burnout.
- Industrial Distribution Panels: Installed upstream of critical loads in manufacturing plants, chemical facilities, and water treatment stations.
- Offshore & Marine Electrical Systems: Provides earth leakage protection in isolated power networks where conventional RCDs are insufficient.
- Building Management Systems (BMS): Integrated into LV switchgear for hospitals, data centers, and high-rise facilities requiring IEC-compliant leakage monitoring.
- Renewable Energy Installations: Ground fault detection in solar inverter output circuits and wind turbine electrical cabinets.
- PLC-Controlled Automation Lines: Paired with safety PLCs to trigger controlled shutdowns upon leakage threshold breach, protecting both personnel and process equipment.

Why Engineers Specify This Model
- Proven Honeywell Reliability: Honeywell’s industrial sensing and protection portfolio is trusted in over 100 countries across process, energy, and manufacturing sectors.
- 3-Phase Architecture: The /3/1 variant is purpose-built for three-phase systems, providing balanced leakage monitoring across all phases simultaneously — eliminating blind spots common in single-phase detectors.
- Relay Output Flexibility: Direct relay contact output integrates seamlessly with existing PLC I/O, SCADA alarm systems, or standalone trip coils — no additional signal conditioning required.
- Compact DIN-Rail Form Factor: Fits standard 35mm DIN rail inside existing control cabinets without requiring panel redesign.
- Deterministic Trip Response: Consistent, repeatable trip timing ensures compliance with safety system response-time requirements in SIL-rated applications.
Complete System Bill of Materials
For a complete earth leakage protection system, engineers typically pair the Honeywell 10310/3/1 with:
- Toroidal current transformer (core balance CT) — matched to cable diameter
- 24 VDC or 110/230 VAC auxiliary power supply
- DIN rail terminal blocks (e.g., Phoenix Contact or Weidmüller)
- Safety relay or PLC digital input module for trip signal processing
- Alarm annunciator or HMI for operator notification
- Circuit breaker or contactor for load isolation upon trip

Application-Specific FAQ
Q: Can the Honeywell 10310/3/1 be used on IT (isolated) power networks?
A: Earth leakage detectors are specifically designed for IT networks where conventional RCDs cannot operate. The 10310/3/1 is well-suited for this application — confirm the sensitivity setting matches your system’s leakage threshold requirements.
Q: What core balance CT ratio is required?
A: The CT selection depends on cable diameter and the desired trip sensitivity. Honeywell provides a CT selection guide for the 10310 series — contact our team for application-specific recommendations.
Q: Is this module compatible with Modbus or other fieldbus protocols?
A: The 10310/3/1 provides a hardwired relay output. For fieldbus integration, the relay output can be wired to a PLC digital input module connected to your Modbus/Profibus/EtherNet-IP network.
Q: What is the difference between the /3/1 and other 10310 variants?
A: The suffix /3/1 denotes the 3-phase, single-relay-output configuration. Other variants in the 10310 series may offer different phase configurations or dual output options. Contact us to confirm the correct variant for your application.
Q: Can I get a datasheet or wiring diagram?
A: Yes — email support@konmask.com with your order reference or inquiry and we will provide the official Honeywell technical documentation.
