Siemens B240 2 Pole 40A Circuit Breaker

Siemens General Application Circuit Breakers are industrial design thermal-magnetic breakers with valuable features for the global market. The BL breaker family features breakers like the EG that are well suited for OEM designed equipment in both light commercial and industrial applications. This breaker family also includes thermal-magnetic breakers, molded case switches and motor circuit protectors.

• All circuit breakers perform the following functions: sense when an over current occurs, measure the amount of over current ACT by tripping quickly enough to prevent damage to itself and associated conductors
• HID lighting - add suffix HID 15 - 30-Amp 1 and double-pole breakers for high-intensity discharge lamp loads having in-rush currents above the instantaneous trip setting of a standard breaker
• Tungsten lighting - add suffix T 15 - 20-Amp single-pole breaker used for high-wattage, tungsten-lamp loads having in-rush currents above the instantaneous trip setting of a standard breaker
• Molded case switch - add suffix S 100-Amp single-pole and 30, 60 and 125-Amp double-pole breakers for applications that do not require over current protection
• Switching neutrals - add prefix BG 15 - 30-Amp 2 and 3-pole breakers used where all conductors are required to be disconnected
• Neutral pole of the circuit breaker does not connect to load center bus one side is wired to neutral and the other side to the device
• Circuit breaker's compact size saves space and its field-installable accessories allow for last minute changes for all applications
