ACI Sparkle MCB 40A Double Pole (DP) C Curve Breaker
Ensure uncompromising electrical safety with the ACI Sparkle MCB 40A Double Pole (DP) C Curve Miniature Circuit Breaker. Designed for precise protection of low-ampere sub-circuits and delicate electrical installations, this Double Pole MCB safeguards appliances and cabling from hazardous thermal overloads and short circuits. Featuring a C-Curve tripping characteristic, it handles mild inrush currents—such as small inductive motor starts or transformer energizations—without nuisance tripping while providing rapid trip response during dead short conditions. Built to handle a 3kA breaking capacity across a 220V–415V AC range, it is an essential safeguard for modern distribution boards in residential, commercial, and industrial settings.
Key Highlights:
Precision Low-Current Protection: Rated at 40A to isolate low-power circuits, sensitive control electronics, and specialized equipment safely.
C-Curve Tripping Dynamics: Calibrated to trip between 5 to 10 times the rated current, absorbing moderate switching surges while instantly cutting dangerous faults.
Rapid Fault Isolation: 3kA short-circuit breaking capacity ensures fast arc suppression to prevent electrical fires and wire damage.
Flame-Retardant Housing: Constructed with durable, high-impact insulation materials for enhanced thermal stability and operator safety.
Compact DIN Rail Design: Fits standard distribution board enclosures with straightforward snap-on installation and clear ON/OFF status indication.
Why Choose This Product?
Protecting low-power sub-circuits requires an MCB that responds accurately without allowing over-current to compromise delicate wiring or sensitive control electronics. The ACI Sparkle 40A DP C-Curve MCB combines responsive thermal-magnetic protection with high-grade internal contact mechanisms to ensure immediate fault interruption. Engineered for smooth compatibility with standard AC distribution boards (220V–415V), it provides dependable, maintenance-free circuit security for residential homes, corporate offices, and commercial panel boxes.
Frequently Asked Questions (FAQ)
What does “C Curve” mean on a 40A MCB?
Answer: A C-Curve MCB is designed to trip magnetically at 5 to 10 times its rated current (200A to 400A for a 40A breaker). This makes it ideal for general lighting, control circuits, and equipment that experiences small initial current surges when turned on.
Where should a 40A Double Pole MCB be used?
Answer: A 40A breaker is typically used for low-wattage sub-circuits, control panels, electronic instrumentation, tiny fan circuits, or low-power lighting lines that require isolated current limits far below general household wall outlets.
What is the advantage of a 3kA breaking capacity?
Answer: Breaking capacity indicates the maximum short-circuit current the breaker can safely interrupt without failing or welding its contacts. A 3kA (3000A) rating ensures reliable protection against standard residential and commercial short-circuit fault levels.
