Information About 140MG-G8P-C30
The 140MG-G8P-C30 belongs to the Allen-Bradley Bulletin 140MG series, which is engineered for high-performance motor branch circuit protection in industrial control panels. As a Type MCP breaker, it provides magnetic-only protection, meaning it does not include thermal overload protection and is typically paired with an external overload relay.
Key Features:
-
30 A Rated Current: Reliable protection for small to medium motors.
-
Adjustable Magnetic Trip: Tailored short-circuit response for different load conditions.
-
65 kA Interrupting Capacity: High fault-current handling for safety and compliance.
-
Motor Circuit Protector (No Thermal Trip): Requires use with external overload relay.
-
3-Pole G-Frame (125 A Max): Supports balanced three-phase protection.
-
Auxiliary + Alarm Contacts: Built-in signaling for monitoring and safety systems.
-
80% Rating: Continuous operation at 80% of nominal rating.
The 140MG-G8P-C30 ensures selective coordination and motor circuit protection in demanding industrial applications.
