SCHNEIDER A9R14491 RCCB Residual Current Circuit Breaker Type AC 4P 100A 300mA

RCD Circuit Breaker SCHNEIDER A9R14491 Residual Current Protective Device, RCCB Type AC 4P 100A 300mA
The Schneider circuit breaker is a residual current circuit breaker (RCCB) in the Acti 9 iID range, essential for electrical system safety. Designed to prevent fire hazards caused by earth leakage currents and protect against electric shock from indirect contact in 3-phase systems. It is a 4-pole (4P) type with a high current rating of up to 100A and a tripping sensitivity of 300mA. Being Type AC, it is ideal for use as a main or upstream leakage current protection device in large power distribution systems. Must be used with an overcurrent circuit breaker (MCB/MCCB) to provide overcurrent and short-circuit protection.

Specifications

- Fire protection and indirect contact electric shock protection

- Suitable for installation as an earth leakage protection device in main distribution boards 

- Capable of detecting pure sinusoidal AC leakage currents, which are common in standard electrical appliances

- The tripping mechanism operates independently of the supply voltage (voltage-independent, no electronic circuits), ensuring that the device trips immediately for safety upon an earth leakage current, even during low voltage or fluctuations

Applications & Usage

- Protects internal circuits in residential/commercial/light industrial buildings that require leakage current protection and reduced fire risk

- Used in systems requiring immediate power disconnection upon earth leakage (e.g., machine rooms, kitchens, water pump systems)

- Suitable for use in combination with branch breakers / MCCBs or other MCBs in control panels
