Square D EDB24020SA E-Frame Molded Case Circuit Breaker – 2 Pole – 20A – 480Y/277VAC – Bolt-On – Thermal Magnetic – Shunt Trip

The Square D EDB24020SA is a molded case circuit breaker designed for industrial and commercial power distribution systems. Manufactured by Schneider Electric, this 2-pole, 20A E-Frame breaker is intended for use in NF panelboards and provides reliable thermal-magnetic protection against overloads and short-circuit conditions.

This unit features a bolt-on mounting design for secure installation into NF panelboard assemblies, ensuring stable electrical connection and simplified integration. A factory-installed shunt trip allows for remote tripping functionality, while the built-in Visi-Trip indicator provides clear visual confirmation of fault conditions for faster diagnostics and maintenance response.

With fixed thermal and magnetic trip characteristics, the EDB24020SA is engineered for consistent protection performance in demanding environments. Its compact E-Frame construction and high interrupting capacity make it suitable for modern electrical distribution systems requiring both reliability and space efficiency.
