ABB 2P 40A 100mA RCCB (FW202) – Residential

The ABB FW202 40A-100mA is a 2-pole Residual Current Circuit Breaker (RCCB) specifically engineered for residential main incomer applications. Rated at 230V with a 40A current capacity, this Type AC device provides dedicated earth leakage protection to prevent fire hazards in domestic wiring systems.

Quick Answer

Absolutely, purchase the ABB FW202 40A 100mA RCCB for superior fire protection in your Indian home's main incomer. Its unique 100mA sensitivity is ideal for detecting significant earth leakages that cause fires, without the nuisance tripping of 30mA units. This 2-pole device offers robust 10kA breaking capacity, ensuring your household wiring remains secure and preventing major electrical hazards.

✓Prevents fire hazards in domestic wiring — 100mA residual current sensitivity initiates instantaneous tripping.
✓10kA conditional short circuit rating — provides high-level durability when paired with a coordinated backup MCB.
✓Durable mechanical life for long-term safety — tested for 10,000 cycles to provide years of reliable switching.
✓Type AC tripping characteristic — specifically designed to detect sinusoidal alternating earth leakage currents.
✓Safe installation with flame-retardant casing — UL94 V-2 flammability rating and 850°C glow wire test compliance.
✓2P configuration with solid neutral — fits a 35mm DIN rail and provides a dedicated path for 230V residential circuits.

Opt for the ABB FW202 40A 100mA RCCB if your primary need is robust fire protection at your residential main incomer in India, prioritizing stability over hyper-sensitive personnel protection. Skip it if you specifically require a 30mA device for direct human safety applications like wet areas.
