Full Product List of the Same Series (Exclusive for T1/T2 160, Not Interchangeable with Other Frames)

This series consists of two independent categories: Shunt Release (SOR) and Undervoltage Release (UVR). Mixing usage is prohibited.

3.1 Shunt Release (Trips when energized, widely used for remote control & fire emergency cut-off)

1SDA054897R1: AC230V 50/60Hz (Main model)
1SDA054898R1: AC400V 50/60Hz

3.2 不足電圧解除 (Trips when power fails, for undervoltage protection)

1SDA054899R1: AC230V
1SDA054900R1: AC400V

Important Reminder

The above part numbers only fit T1 160 / T2 160. ABB T3/T4/T5/T6 large-frame MCCBs adopt another set of 1SDA codes and have incompatible physical structures.

Production Status & Original Replacements
Production Status: In regular mass production. No discontinuation, phase-out or upgrade plan.
Version Compatibility: R1 is the universal version for the whole series. Products of new and old batches are 100% interchangeable in hardware, wiring and functions, and can be mixed on site.
Original Replacements: No equivalent original models available. Use 1SDA054897R1 directly for procurement.

アプリケーションシナリオ & Operating Restrictions

✅ Recommended Applications

Fire Emergency Cut-off Circuit (最も一般的な): Linked with fire alarm control panel to cut off non-fire loads in buildings.
Intelligent Power Distribution System: Remote tripping via PLC, DCS and smart meters.
Remote Operation for Transformer Cabinets & Distribution Rooms: Power cut for unattended stations.
Industrial Safety Circuits: Main power disconnection linked with equipment emergency stop and safety signals.
Remote control of main power & lighting circuits in shopping malls, factories and buildings.

❌ Prohibited & Restricted Applications

直流制御回路: This product is designed for AC only. DC supply causes malfunction and permanent damage.
Continuous long-term energization: Violates short-time duty design and will burn out the coil.
High-frequency repeated operation: 以上 10 operations per minute will drastically shorten service life.
Outdoor exposed areas with rain, heavy corrosion or conductive dust: IP20 provides no water or corrosion resistance. A sealed cabinet is mandatory.
Operation above 2000m without derating: Insulation performance decreases at high altitude, leading to false tripping and creepage faults.
インストール, 配線 & Safety Regulations

7.1 Pre-installation Requirements

Cut off the upstream main power supply completely and verify zero voltage inside the cabinet before work. Live installation and disassembly are strictly forbidden.

Snap-fit installation: Align the accessory with the dedicated slot inside the circuit breaker and press to lock. No extra screws are needed.

Post-installation test: Manually close and trip the breaker 3 に 5 times to confirm smooth mechanical movement without jamming.

7.2 Wiring Regulations

The product is fitted with two flexible leads. The AC circuit is non-polarized; connect directly to the external control circuit.
Install a 1A~2A miniature fuse in series in the control circuit to prevent fault spreading caused by coil short circuit.
Separate strong and weak current wiring: Run control cables separately from main power cables to avoid electromagnetic interference.
制御ロジック: Adopt pulse triggering (energization duration: 1~3s). Continuous power supply is forbidden.

7.3 Working Principle Summary

Coil energized → Trigger tripping → Circuit breaker trips. The tripping mechanism remains locked after power cut; manual closing is required for reset.

トラブルシューティング & メンテナンス

故障 1: Circuit breaker fails to trip after energization

考えられる原因: No power / low voltage in control circuit, broken leads / loose connections, open coil circuit, 機械的な妨害

トラブルシューティングの手順:

Measure voltage across leads with a multimeter to ensure it is within AC161V~253V.
Check cable continuity and terminal tightness; replace damaged leads immediately.
Remove the accessory after power cut and clean dust and foreign objects inside the mechanism.
Replace with new 1SDA054897R1 if voltage and wiring are normal but no operation (coil burnout).

故障 2: Repeated coil burnout and overheated insulation

Root Causes: 連続通電, 過電圧, surge impulse

ソリューション:

Modify control logic and add an intermediate relay for short pulse triggering.
Install varistors or surge absorbers in the control circuit to suppress voltage spikes.
Inspect upstream power supply to eliminate three-phase unbalance and overvoltage issues.

故障 3: Accidental tripping without control signal

原因: Induced voltage from mixed strong/weak current wiring, cable leakage, loose assembly

ソリューション:

Run control cables in separate conduits or use shielding for physical isolation from power cables.
Connect a bleeder resistor in parallel with the control circuit to eliminate induced voltage.
Re-seat the snap fastener to ensure firm assembly.

故障 4: Slow or incomplete tripping

原因: Dust and debris trapped in mechanical mechanism

解決: Blow clean with dry compressed air after power cut. Do not disassemble the mechanism or add lubricant (Factory-applied grease is designed for full service life).

認証, ロジスティクス & Storage Requirements
認証: Approved with CCC (中国の強制認証) とCE (EU Certification), compliant with domestic projects and export to EU countries.
ストレージ: Store in cool and dry environment; avoid moisture and heavy compression.
Transportation: Pure electromagnetic coil component, no lithium batteries or magnetic dangerous goods. Classified as general cargo for air and sea transportation with no special restrictions.
