£28.57
The Chint NB1-63CH3P10 is a compact and dependable miniature circuit breaker (MCB) designed to protect low voltage electrical circuits against overloads and short circuits. As part of the Chint NB1-63H series, it provides reliable circuit protection for residential, commercial and industrial electrical installations where a higher breaking capacity is required.
This 3 pole C curve MCB features a 10 A rated current, making it suitable for three-phase lighting circuits, control circuits, instrumentation systems, small transformers and lightly inductive loads. The C curve tripping characteristic allows for moderate inrush currents, making it suitable for mixed resistive and inductive applications.
With a rated short-circuit breaking capacity of 10 kA and a standard 35 mm DIN rail mounting format, the NB1-63CH3P10 is easy to install within distribution boards and electrical control panels. Its 3 pole design provides simultaneous isolation and protection across all three phases.
Miniature circuit breakers such as the Chint NB1-63CH3P10 automatically disconnect electrical circuits when overloads or short circuits occur. This helps protect wiring, connected equipment and electrical installations from excessive current and fault conditions.
The C curve characteristic trips between five and ten times the rated current, making it suitable for mixed resistive and inductive loads, lighting circuits, control circuits, instrumentation circuits, relays, small transformers and three-phase circuits with moderate inrush current.
