The BCH Tem Power-2 range of air circuit breakers ensures extremely fast interruption of short-circuit current due to its "double break" main contact system. A unique arc chamber design permits vertical stacking, which minimises switchboard height and saves valuable panel space in heavy-duty electrical installations.

The TemPower2 series comes equipped with RMS-sensing over-current releases (OCR), offering a wide range of protection functions and capabilities. Standard protection includes long time delay, short time delay and instantaneous tripping, while optional protection covers ground fault, reverse power trip, N-phase protection, earth leakage, two-channel pre-trip, an advanced LCD display, contact temperature monitoring and communication protocol support.
