Information About 140MG-G8P-C50
The 140MG-G8P-C50 is part of Allen-Bradley's G-Frame series of motor protection devices, offering adjustable magnetic trip protection and high fault current interrupt capability. With a frame rating of 125 amps and a 3-pole configuration, it supports motor branch circuits requiring tailored short-circuit protection. The MCP is designed without thermal elements, making it suitable for applications where overload protection is provided externally or by electronic motor protection relays.
Key Features:
-
Adjustable Magnetic Protection: Allows setting flexibility for specific short-circuit trip thresholds.
-
High Interrupting Capacity: Rated at 65 kA at 480V AC for dependable circuit isolation during fault conditions.
-
No Thermal Trip Element: Provides short-circuit protection only, ideal for systems with separate overload protection.
-
3-Pole G-Frame Design: Supports motor circuits with up to 50A operational current and 125A frame capacity.
-
Auxiliary and Alarm Contacts: Built-in signaling options enhance monitoring and maintenance efficiency.
The 140MG-G8P-C50 is ideal for motor protection in automation systems, HVAC, pumping stations, and factory machinery that require flexible, high-performance short-circuit safeguarding.
