The NOARK B1N3C63 is a robust 3-pole circuit breaker designed for 63A capacity at 240VAC. Featuring a reliable 10kA short-circuit protection, this DIN rail-mounted breaker ensures optimal performance in various applications. Ideal for both residential and commercial use, it guarantees safety and efficiency in your electrical systems.
The NOARK B1N series breakers are designed to meet IEC 60947-2 standards. For use in Canadian installations, verify that the specific unit carries the required CSA or cUL certification, and confirm compliance with your local authority having jurisdiction (AHJ). Our team can help clarify certification details — contact us for documentation support.
The B1N3C63 may serve as a functional replacement for other IEC-standard 3-pole 63A DIN rail breakers, provided the voltage rating (240VAC), breaking capacity (10kA), and physical DIN rail dimensions are compatible. However, cross-brand replacements should always be verified against the original specification sheet and approved by a licensed electrician. Contact us with the original breaker's part number and we can help assess compatibility.
The 'C' in B1N3C63 denotes a Type C trip curve, which is designed to handle moderate inrush currents — typically 5 to 10 times the rated current before tripping. This makes it well suited for resistive and low-inductive loads such as lighting circuits, distribution boards, and general commercial or industrial loads. For motor-heavy applications with high inrush, a Type D curve breaker may be more appropriate. Not sure which curve suits your load? Contact our team and we'll help you select the right breaker.
