Circuit breaker iC60H-B20-1 20A 1-pole A9F06120

Circuit Breakers iC60 – Reliable Installation Protection

This single-pole circuit breaker iC60H-B20-1 with a rated current of 20A is a basic protection element in every electrical installation. It provides effective protection against the effects of overloads and short circuits, protecting both devices and the installation. It is an ideal solution for both installers and end-users who value safety and reliability.

Circuit breakers from the iC60 series are versatile – they meet the requirements of both IEC/EN 60947-2 (industrial application) and IEC/EN 60898-1 (residential construction) standards. This allows them to be used in a wide range of facilities: from residential homes, through commercial buildings, to industrial facilities. The breaker design allows for easy mounting on a DIN rail, and the removal of a single device does not require disconnecting the entire rail.

Constructional features and functionality

The iC60H-B20-1 circuit breaker stands out with several important features that facilitate its installation and use. Characteristic B means that the breaker reacts quickly to current increase – it will trip after 3-5 times the rated current. This makes it particularly useful in circuits with resistive loads, such as lighting or household appliances with low surge levels. The VisiTrip indicator allows for quick identification of the cause of the trip – a red color indicates tripping caused by a fault. Additionally, the VisiSafe indicator informs about the physical opening of the contacts, which increases safety during maintenance work. The possibility of connecting two wires of different cross-sections (from 1 to 25 mm² for solid and from 1 to 16 mm² for stranded) provides flexibility during installation.

Technical parameters ensuring safety

The circuit breaker has a rated voltage of 230V and a rated insulation voltage Ui of 500V. The rated short-circuit breaking capacity Icn is 10kA at 230V (according to EN 60898), and Icu is 15kA (according to IEC 60947-2). The rated impulse withstand voltage Uimp is as high as 6kV. The energy limitation class is 3, and the surge category IV – these parameters guarantee high resistance to working conditions in various electrical installations. Power losses are only 2.4W while maintaining high protection efficiency. The degree of protection is IP20, providing protection against accidental contact. The circuit breaker operates in an ambient temperature range from -35°C to +70°C.
