Miniature motor circuit breaker GB 5A 1P GB2CB10

Installation and motor protection with circuit breaker GB2CB10

Miniature motor circuit breaker GB2CB10 is a reliable protection for electrical circuits, designed to protect motors and installations against overloads and short circuits. This single-pole (1P) circuit breaker with a rated current of 5A, from Schneider Electric, is a key element in ensuring the safety and continuity of device operation. Its compact size and 35mm rail mounting make it an ideal solution for both installers and end users.

Characteristics and application

The GB2CB10 circuit breaker with a "Other" tripping characteristic (in practice, this means a C characteristic), provides effective protection against the effects of sudden current surges, typical for starting motors. Thanks to this, the device is resistant to temporary overloads while ensuring a quick response in the event of a short circuit. The rated short-circuit breaking capacity (Icu) is 2kA at 230V AC, which guarantees safe disconnection of the circuit in the event of a failure. A width of 1 module allows for optimal use of space in the switchgear cabinet. This circuit breaker is used in a wide range of applications, from protecting electric motors in commercial and industrial buildings to protecting circuits in home installations.

Construction and technical parameters

The GB2CB10 circuit breaker is designed for durability and reliability. The housing made of high-quality materials provides resistance to mechanical damage and external factors. The ability to connect wires with a cross-section from 0.75 mm² to 4 mm² (multi-strand) and from 0.75 mm² to 6 mm² (solid) provides flexibility during installation. The IP20 degree of protection protects against finger contact and the ingress of solid objects larger than 12.5mm, which increases safety. The device operates in an ambient temperature range from -20°C to 60°C, allowing it to be used in various environmental conditions. The rated impulse withstand voltage Uimp is 4kV, which further increases resistance to overvoltages. The energy limitation class is 3 and the surge category is also 3 – standard values for this type of device.
