Information About 140MT-C3E-B40
The 140MT-C3E-B40 is a motor protection circuit breaker manufactured by Allen-Bradley for safeguarding motors in industrial electrical installations. It is designed in a compact DIN rail mount format, allowing easy installation within motor control panels and distribution boards. The device combines thermal overload protection with magnetic short-circuit protection to ensure reliable interruption under fault conditions. It is commonly used in motor starter assemblies, conveyor systems, pumps, and machinery where controlled motor protection and operational safety are required.
Key Features:
- Adjustable overload protection: Allows precise current setting between 2.5 and 4 A to match specific motor requirements.
- Integrated thermal protection: Protects motors from sustained overcurrent conditions that could lead to overheating and damage.
- Magnetic short-circuit response: Provides fast interruption during short-circuit events to minimize equipment stress.
- Wide voltage operating range: Supports rated operating voltages from 200 to 690 V for flexible industrial use.
- High breaking capacity: Rated for up to 100 kA at 400 V AC, suitable for high-fault-level installations.
- Three-pole configuration: Designed for three-phase motor circuits in industrial environments.
- DIN rail mounting design: Enables straightforward installation and integration into standardized control panels.
- Manual control interface: Uses a turn-button knob for simple operation, reset, and status indication.
The 140MT-C3E-B40 delivers the reliability and precision required for effective motor protection in industrial electrical and automation systems.
