BF226 Description

Short technical summary and product information.

The COSEM BF226 is a 2-pole differential circuit breaker designed for electrical installations requiring reliable protection against earth leakage currents. It features a rated current of 25A and a residual operating current of 300mA, suitable for AC type protection.

 

This device operates at a nominal voltage of 230/400V with an insulation voltage of 500V and an impulse withstand voltage of 4000V. It has a rated frequency of 50 Hz. The circuit breaker has a compact design, with a width of 3.5 cm, height of 7 cm, and installed depth of 9.2 cm, fitting into 2 modules.

 

Installation is facilitated by a tightening torque of 1.7 Nm for the terminals, with a specific torque of 2.2 Nm for the lower terminal. It supports rigid cables up to 10 mm² and flexible cables up to 6 mm². The device has an IP20 protection rating, indicating protection against solid objects larger than 12.5mm but not against water.

 

Electrical endurance is rated for 2000 cycles, and mechanical endurance for 2000 maneuvers. The operating temperature range is from -5°C to 40°C, with storage temperatures between -25°C and 70°C. It is designed for use at altitudes up to 2000m.
