EATON BW2175 Circuit Breaker, 120/240 VAC, 175A, 10 kA Interrupt, 2P

Eaton BW2175 circuit breaker is an Eaton Type BW main circuit breaker used for protecting connected devices from electrical damages due to overload (excess current) or short circuits. It controls power to the heating, air conditioning and refrigeration (HVAC) equipment.

Working Mechanism:

• Normally, this Eaton BW2175 circuit breaker's contacts pass current through them.
• When these contacts detect any fault, they move away from each other to trip the unit thermally or magnetically.
• Users can reset the breaker after troubleshooting the issue to restart the operation.

Features:

• Eaton BW2175 circuit breaker accommodates 2 AWG to 300 kcmil wires made of aluminium or copper.
• Its plug-on mounting style with line side terminals allows easy installation on panels or switchboards.
• This 2-pole circuit breaker is equipped with thermal & magnetic contacts for quick protection of connected circuits.
• It combines in series with BD, BR, BQ, BQC & GFCB type breakers for interrupt rating of 22kAIC (with BRH main) and 25kAIC (with BWH main).

Compatible Accessories:

• Eaton ECB Type Unit Enclosures: This Eaton BW2175 breaker can easily fit onto these unit enclosures for smooth operation, easy control and preventing accidental contact of energized parts.
• Load Centres And Panels: This circuit breaker installs on the load centres for quick control of the connected circuits.
