Key Technical Specifications

Specifications are based on ABB product documentation and catalog data. The TVOC-2-240 base model includes an HMI; the communication module is a separate accessory.

Product Introduction (Anti-Template)

When an arc fault develops inside metal-enclosed switchgear, the time available to protect personnel and equipment is extremely limited. The ABB TVOC-2-240 is the main monitoring unit in the TVOC-2 Arc Guard System. It detects arc light through connected optical detectors and sends a trip signal to the associated circuit-breaker control circuit within 1 ms, helping reduce the duration of damaging arc-fault energy.

The base unit supports 10 optical detector inputs and can be expanded to support up to 30 detectors using compatible extension units. The TVOC-2-240 operates from 100–240 V AC or 100–250 V DC and includes an HMI with door-mounting accessories. Verify the supply voltage, detector arrangement, trip-circuit design, and exact order code before replacing an installed unit.

QC, Procurement & Logistics SOP

1. Inbound Verification
   Check the ABB nameplate, model TVOC-2-240, order code 1SFA664001R1001, housing condition, terminals, and included HMI/accessories. Confirm the ordered version against the existing switchgear documentation.
2. Live Rig Testing
   Where suitable test equipment and an approved setup are available, verify power-up behavior, optical detector response, trip-output operation, and alarm indications. Do not treat a power-on check alone as proof of complete arc-protection functionality.
3. QA & Anti-Static Packaging
   Inspect the enclosure and connection points for visible damage. Protect the unit against electrostatic discharge, moisture, and impact during packing and transport.
4. Global Logistics & Export Compliance
   Confirm destination, shipping method, documentation requirements, and applicable customs classification before dispatch. Pack the unit securely for international air or sea freight and provide tracking details after shipment.

Technical Pitfalls & Integration Warnings

1. Supply Voltage Mismatch

The TVOC-2-240 supports 100–240 V AC or 100–250 V DC. Do not substitute the TVOC-2-48 version, which is designed for a different supply range, without verifying the installation requirements. Applying an incorrect supply can prevent operation or damage the equipment.

2. Detector Cable and Extension Compatibility

The base unit supports 10 optical detector inputs. Additional detectors require compatible extension units, and some extension versions are intended for specific detector cables. If a retrofit increases the number of monitored compartments, check the extension-unit model and detector-cable requirements before installation.

3. Trip Circuit and Zone Selectivity Configuration

The sends a trip signal; it does not mechanically interrupt the fault current itself. The associated circuit breaker and trip circuit must be correctly wired and tested. If zone selectivity is used, verify the detector-to-zone mapping and breaker assignments. An optical detector that works correctly cannot compensate for an incorrectly wired or untested breaker trip circuit.

4. Firmware, Configuration, and ESD Precautions

This is an arc monitor rather than a general-purpose PLC CPU, so controller-style firmware or DIP-switch assumptions should not be applied without checking the relevant manual. Confirm the configuration and any optional communication hardware against the installed system. During unboxing and installation, use appropriate ESD handling and avoid touching exposed electronic connections.

Frequently Asked Questions (FAQ)

Q1: What does the ABB do?

It detects arc light inside protected electrical equipment and sends a rapid trip signal to the associated circuit-breaker control circuit to help limit arc-fault damage.

Q2: How many optical detectors can be connected?

The base unit supports 10 optical detector inputs. Compatible extension units can increase the total capacity to as many as 30 detectors. Check extension and detector compatibility before expanding an existing installation.

Q3: Does the include a communication module?

The specified 1SFA664001R1001 version includes an HMI and door-mounting accessories. The TVOC-2-COM communication module is a separate accessory for Modbus RTU connectivity. Confirm the required configuration when ordering.

Q4: Can the be replaced while the switchgear is energized?

Do not assume live replacement is safe. Arc-protection equipment is part of the switchgear protection scheme, and removing it may leave the equipment without the intended protection. Follow the site’s approved isolation and maintenance procedure, and verify the protection system before returning the switchgear to service.

Q5: Is the interchangeable with the TVOC-2-48?

No, not without checking the supply requirements. The supports 100–240 V AC or 100–250 V DC, while the TVOC-2-48 is designed for 24–48 V DC. Match the supply rating and complete order code before purchasing.

Q6: What is the typical international delivery time?

Lead time depends on confirmed stock, unit condition, inspection requirements, and destination. Contact us to confirm availability and the estimated dispatch date before placing an order.

Q7: Can you arrange international shipping and export documentation?

Shipping options and available documents depend on the destination and order requirements. Provide the delivery country, quantity, and preferred shipping method when requesting a quotation.
