Siemens ED63A125 Motor Circuit Protector (MCP) – Sentron Series – ED Frame – 125A – 3 Pole – 600V – Magnetic Only – Bolt-On

The Siemens ED63A125 is a Sentron Series motor circuit protector (MCP) designed specifically for motor branch-circuit protection in industrial and commercial electrical systems. This 125A, three-pole device operates at 600V and uses a magnetic-only trip system, providing instantaneous short-circuit protection without thermal overload protection.

Built on the ED frame platform, the ED63A125 is intended for use in combination motor controllers where overload protection is provided separately. Its high interrupting capacity ensures reliable performance in demanding motor control applications.
