Siemens ED41B040 is a molded case circuit breaker designed for reliable overcurrent protection in single-phase electrical systems. It features a 40A current rating and a 120V AC voltage rating, housed within a compact 125A/ED frame measuring 0.787" x 4.724" x 5.916" (20mm x 120mm x 150mm) and weighing 0.851 lb. The breaker provides thermal-magnetic protection with long-time and instantaneous (LI) trip functions, ensuring compliance with IEC and UL standards for safety and interoperability. Its 65kA interrupting rating at 120V and a wide operating temperature range of -25°C to 70°C make it suitable for installation in Sentron panelboards and SB switchboards, accommodating copper or aluminum conductors from AWG 10 to 4 via its load-side lug connection.
