Features:
- Rapid Field Replacement with Zero Downtime
- SIL 3-Compliant Overcurrent Protection
- Hazardous Area Certification (Class I, Div 2)
The ICS Triplex T9902 utilizes an accessible surface-mount fuse block on the T9852 termination assembly. Unlike traditional soldered fuses, this design allows a technician to replace a blown fuse in under 60 seconds, restoring output channel functionality without removing the I/O module or disturbing field wiring—critical for maintaining high availability in business-critical processes.
Engineered specifically for safety instrumented functions, the ICS Triplex T9902 provides precise fast-acting interruption at 10A/125V. This exact rating ensures that diagnostic tests run by the T9110 processor do not falsely trip due to thermal drift or voltage sag, maintaining up to SIL 3 integrity for emergency shutdown (ESD) and fire & gas (F&G) loops without compromising channel safety accuracy.
The ICS Triplex T9902 is fully certified for use in explosive atmospheres when installed in the AADvance TA. It maintains the equipment’s suitability for Class I, Division 2, Groups A, B, C, D environments. The fuse’s robust ceramic body prevents arc flash hazards, complying with ATEX/IECEx requirements that the enclosure must remain "IP54 and tool-accessible."
The T9902 ICS Triplex Replacement Input Fuse Kit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Emergency Shutdown Systems (ESD): The ICS Triplex T9902 protects solenoid valves and actuators in high-risk oil & gas platforms, ensuring that a short circuit in one valve does not crash the entire logic solver power bus.
- Fire & Gas (F&G) Systems: In refinery fire panels, this fuse secures notification appliances (horns/strobes). Its fast-acting nature allows the T9451 module to clear faults before the 24V field supply collapses, maintaining alarm audibility.
- Burner Management Systems (BMS): For boiler shut-down valves, the ICS Triplex T9902 provides the precise overcurrent trip point required by NFPA 85/86, preventing welded relay contacts that could lead to burner explosions.
- Turbine Control: For critical auxiliary pumps, using the ICS Triplex T9902 ensures vibration tolerance, preventing nuisance fuse failures due to mechanical resonance that standard glass fuses would suffer.
- IEC 61508 SIL 3 Ready: While the fuse is a simple element, it is the only fuse qualified for use in TÜV-certified AADvance loops. Substituting a generic 10A fuse voids the SIL 3 rating for that channel due to unknown I²T melting integrals.
- ATEX/IECEx (Ex ec IIC T4 Gc): The ICS Triplex T9902 allows the T9852 assembly to retain its "Increased Safety" rating. It is designed to not produce sparks or excessive temperatures even under fault conditions up to 125V.
- UL 248-14 Recognition: Listed under File Number E251761, the ICS Triplex T9902 meets the requirements for Industrial Control Equipment in Non-Hazardous and Hazardous (Class I, Div 2) locations.
- RoHS/WEEE Compliance: The ICS Triplex T9902 is lead-free and fully recyclable, meeting the Waste Electrical and Electronic Equipment directive for disposal in European markets.
- Wide Ambient Operation: The ICS Triplex T9902 supports continuous operation from -25°C to +70°C (-13°F to +158°F), suitable for un-conditioned outdoor cabinets in the Middle East or Arctic drilling sites.
- Humidity Endurance: Rated for 10% to 95% relative humidity (non-condensing). The surface mount block material is hydrolysis-resistant, preventing the "green crust" corrosion seen in standard fuse holders after 5 years of tropical deployment.
- Vibration Resistance: Unlike glass fuses that fracture, the ICS Triplex T9902 ceramic body withstands 0.5g acceleration (10-150 Hz) and 15g shock pulses, making it ideal for reciprocating compressor skids and offshore wind turbine nacelles.
- Altitude Capability: Certified for operational use up to 2,000 meters (6,600 ft.) without de-rating, and transport up to 3,000 meters, ensuring global logistics compliance for high-altitude mining projects in the Andes.
