Schneider Acti9 MCB 4 Pole 63A C Curve 10kA – Heavy-Duty Protection for Critical Three-Phase Systems
Ensure maximum safety and performance in high-load electrical systems with the Schneider Acti9 MCB 4 Pole 63A C Curve 10kA, designed for industrial, commercial, and heavy-duty residential applications. This Miniature Circuit Breaker (MCB) provides complete protection against overloads and short circuits across all three phases and neutral, ensuring total circuit safety.
Part of Schneider’s trusted Acti9 xC60 series, this MCB features a 63A current rating, making it ideal for main distribution boards, large machinery, HVAC systems, and high-power electrical installations. Its 10kA breaking capacity ensures reliable interruption of fault currents, protecting wiring and connected equipment from electrical damage.
The C curve tripping characteristic is designed for circuits with moderate inrush currents (typically 5–10 times the rated current), making it suitable for inductive loads such as motors, pumps, compressors, and air conditioners. This ensures fast response during faults while preventing nuisance tripping during normal operation.
With a 4-pole (4P) configuration (3P + N), this MCB provides complete isolation of all three phases and neutral, which is essential for safe maintenance and fault handling. It is widely used in industrial panels, commercial installations, and critical infrastructure systems where full circuit disconnection is required.
The breaker supports DIN rail mounting, allowing quick and secure installation in standard electrical panels. Built in compliance with IS/IEC standards, the Acti9 range ensures durability, consistent performance, and long service life even in demanding environments.
