Eaton PLSI‑C10/3 MCB FAQs

Q: ❓ What is the Eaton PLSI‑C10/3‑GI MCB?

The Eaton PLSI‑C10/3‑GI is a Miniature Circuit Breaker (MCB) rated at 10A, with a C-curve tripping characteristic. It features a three-pole (TP) configuration, making it suitable for three-phase electrical systems commonly found in Indian homes, small businesses, and light-industrial setups. ⚙️ Key Technical Specifications Rated Current (In): 10A Trip Curve: C-Curve (5–10× In) Rated Voltage: 240/415 V AC Breaking Capacity: 10kA Poles: 3 (Triple Pole) Standards: IS/IEC 60898-1, ISI & CE Certified Mounting: DIN-Rail 🧠 Frequently Asked Questions

Q: 1. ✅ What is the use of a C-Curve MCB?

C-curve MCBs are designed to trip when the current reaches 5 to 10 times the rated current (In). They are ideal for inductive loads like motors, compressors, HVAC units, and pumps, which have higher inrush currents during startup.

Q: 2. ✅ Can I use this MCB in residential panels?

Absolutely! The Eaton PLSI‑C10/3‑GI is ideal for residential three-phase distribution boards, especially where individual neutral isolation and energy-limiting protection are required.

Q: 3. ✅ Is this MCB ISI certified?

Yes, it is ISI and CE certified and fully complies with IS/IEC 60898-1 standards, making it reliable and approved for use across India.

Q: 4. ✅ What makes it suitable for Indian conditions?

The MCB is engineered with fire-retardant housing, true isolation, and operates efficiently in a wide temperature range (–5 °C to +50 °C) with high humidity resistance (up to 95% RH). It’s truly a “Made for India” product.

Q: 5. ✅ Can this MCB be used in HVAC systems?

Yes. The C-curve tripping makes it perfect for inductive HVAC loads, ensuring protection during compressor startup without unnecessary tripping.

Q: 6. ✅ What are the wiring terminal specs?

It supports: Up to 25 mm² solid conductors Up to 16 mm² flexible wires Uses M5 combi-screws tightened to 2 Nm

Q: 7. ✅ Is there a visual trip/contact indicator?

Yes! A true contact position indicator helps clearly distinguish ON (red) and OFF (green) states, ensuring maintenance safety and easy troubleshooting.

Q: 8. ✅ Can I use this in OEM panels or retrofits?

Definitely. With its 17.5 mm per pole modular width, the unit fits snugly into compact panels. It’s a favorite among panel builders for OEM and retrofit jobs.

Q: 9. ✅ How long will this MCB last?

It offers: Mechanical Life: 10,000 operations Electrical Life: 4,000 operations That’s long-term reliability for years to come.
