Ask an expert
The Square D EJB14020 is a high-interrupting capacity molded case circuit breaker designed for commercial and industrial electrical distribution systems. Manufactured by Schneider Electric, this 1-pole, 20A breaker provides dependable thermal-magnetic protection against overloads and short-circuit faults while maintaining compatibility with Square D NF panelboards.
As part of the EJB Series E-Frame product family, the EJB14020 features a bolt-on mounting design for secure installation and long-term reliability. Its high interrupting capacity makes it well suited for applications where elevated fault current levels are present, delivering up to 65kA interrupting capacity at 277VAC and 240VAC, and 100kA at 120VAC.
The breaker incorporates a thermal-magnetic trip unit with long-time and instantaneous protection functions, along with a visual trip indicator for quick fault identification. Designed for operation in 40°C environments, it is both HID-rated and HACR-rated, making it suitable for lighting and HVAC applications.
