LEGRAND DX3 4202 08

Legrand DX3 4202 08 Miniature Circuit Breaker Description The Legrand 4202 08 is a DIN rail mountable Miniature Circuit Breaker (MCB) from the DX3 series. This device provides essential overcurrent and short-circuit protection for electrical installations. It features a 1P+N configuration, a rated current of 4A, and a C-type tripping curve, making it ideal for general-purpose applications in commercial and industrial environments. Specifications Manufacturer: Legrand Part Number: 4202 08 Series: DX3 Rated Current: 4A Tripping Curve: C Number of Poles: 1P+N Rated Voltage: 230V AC Frequency: 50/60Hz Breaking Capacity (Icu): 6 kA (IEC 60947-2) Mounting: DIN Rail Label Info Legrand 4202 08 C4 / 6000 IEC 60947-2 Cat. A Application This MCB is commonly used in distribution boards to protect final circuits for lighting, sockets, and other general loads against overload and short-circuit faults. The 1P+N design ensures complete isolation of the circuit for maintenance and safety. Country of Origin Made in France. CO2 Impact By purchasing this reused Legrand MCB, you are contributing to a circular economy and helping to avoid 4.8 kg of CO2 emissions associated with the production of a new unit. This saving is equivalent to the emissions from driving a standard car for approximately 24 kilometers. Availability This item is a used, tested product in excellent working condition.

FAQ What is the difference between a C-curve and a B-curve circuit breaker?A C-curve breaker, like this Legrand 4202 08, is designed for general purpose applications with moderate inrush currents, like lighting and standard outlets. It trips between 5 and 10 times the rated current. A B-curve breaker is more sensitive, tripping between 3 and 5 times the rated current, and is used for resistive loads with little to no inrush current. What does the ‘6000’ and ‘Icu=6 kA’ rating mean?Both ratings refer to the breaker’s short-circuit breaking capacity. The ‘6000’ (or 6kA) under the IEC 60898-1 standard is for residential use, while ‘Icu=6 kA’ (Ultimate Breaking Capacity) under the IEC 60947-2 standard is for industrial applications. It means the device can safely interrupt a fault current of 6000 Amperes without being destroyed. Can this 1P+N breaker be used on a circuit without a neutral wire?No, this is a 1P+N (single pole + neutral) breaker. It is specifically designed for single-phase circuits that have both a phase (live) and a neutral conductor. The neutral pole is switched along with the phase pole, providing full isolation. Using it without a neutral would be incorrect and potentially unsafe. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
