Schneider 4P 125A 30mA Type B RCCB (16763) –

The Schneider Electric 16763 is a high-capacity 4P (4P) RCCB designed for industrial applications with a 125A rated current and 30mA sensitivity.

Quick Answer

Absolutely, you should consider the Schneider 16763 if your industrial setup in India requires advanced earth leakage protection for systems with AC and DC components. Its 125A capacity and 30mA Type B sensitivity are essential for safeguarding high-power machinery and personnel from severe electrical faults, including those generated by variable frequency drives. This RCCB ensures rapid tripping, preventing cardiac arrest and maintaining system integrity under fault conditions.

✓Protects workers from direct contact hazards — 30mA sensitivity triggers a shutdown in under 300ms at 1x Idn.
✓Heavy-duty 125A rated current capacity allows this 4-module (72mm) unit to manage large industrial power loads.
✓Prevents fire hazards in high-heat environments — Glow wire tested to 960°C with UL94 V 0 flammability rating.
✓10kA conditional short circuit rating provides high-level resilience when paired with a compatible backup MCB.
✓Simplifies troubleshooting and maintenance — Features a blue test button and a dedicated mechanical trip indicator.
✓Exceptional electrical longevity for heavy use — Rated for 10,000 electrical cycles at 50 Hz frequency.

Opt for the Schneider 16763 if you manage industrial facilities with heavy machinery, VFDs, or EV charging stations requiring robust Type B earth leakage protection. Avoid if your application only deals with standard AC loads, as its advanced features and price point are overkill for simpler residential or commercial setups, where a Type A RCCB would suffice.

Product Overview
The Schneider Electric 16763 is a high-capacity 4P (4P) RCCB designed for industrial applications with a 125A rated current and 30mA sensitivity. As a Type B residual current device, it is installed as a main incomer to provide comprehensive earth leakage protection across a 400V (184–440V) range. This instantaneous tripping device is essential for systems where DC components may be present, ensuring total circuit isolation during faults.

Engineering Analysis
The 30mA sensitivity is vital for industrial personnel protection as it ensures the device trips in ≤40ms at 5x Idn to prevent cardiac arrest. With a 10kA conditional short circuit rating and a 1250A making/breaking capacity, this RCCB maintains structural integrity during high-energy faults at the main incomer. The 4P configuration is necessary for 400V systems to ensure the neutral is disconnected alongside all three phases for complete galvanic isolation during a leakage event.
