Description
Product Name: 1492-CB2H020 Allen Braley Input module
Product details:
The Allen-Bradley 1492-CB2H020 is a high-density, thermal-magnetic supplementary protector designed for precision circuit protection in industrial control systems. Part of the 1492-CB series, it is specifically engineered for applications requiring high vibration resistance and compact DIN rail mounting.
## Product Overview
The 1492-CB2H020 is a 2-Pole, 2 A circuit breaker featuring a High-Inrush (Type H) tripping characteristic. It serves as a supplementary protector, meaning it is intended to provide localized protection for equipment where branch circuit protection is already provided or not required.
## Technical Specifications
| Parameter | Specification |
| Catalog Number | 1492-CB2H020 |
| Number of Poles | 2-Pole |
| Rated Current ($I_n$) | 2 A |
| Trip Curve | Type H (High Inrush / Magnetic Trip 6–10x $I_n$) |
| Voltage Rating | 480Y/277V AC |
| Interrupting Capacity | 5 kA |
| Mounting Type | DIN Rail (35mm) |
| Terminal Type | Finger-safe screw terminals |
| Operating Temperature | -25°C to +55°C (-13°F to 131°F) |
## Key Product Advantages
-
High-Inrush Capability: The “H” curve is optimized for circuits with high peak currents, such as small motors or transformers, preventing nuisance tripping during startup.
-
Space Efficiency: Its slim profile allows for high-density installation in crowded control cabinets.
-
Thermal-Magnetic Trip: Combines a delay for sustained overloads (thermal) with an instantaneous trip for short circuits (magnetic).
-
Enhanced Reliability: Built to withstand industrial environments with high vibration and shock ratings.
-
Finger-Safe Design: Terminals are designed to prevent accidental contact with live parts, enhancing maintenance safety.
## Product Applications
This specific model is widely used in the following scenarios:
-
Industrial Control Panels: Protecting PLC (Programmable Logic Controller) I/O modules and power supplies.
-
Solenoids and Valves: Handling the inductive spikes common in pneumatic and hydraulic control.
-
Control Transformers: Protecting the secondary side of small transformers.
-
Heating and Cooling Systems: Providing localized protection for fans or small heating elements.
## Important Considerations & Precautions
-
Supplementary vs. Branch Protection: Note: The 1492-CB series is a UL 1077 Recognized supplementary protector. It should not be used as a primary branch circuit protector (which requires UL 489 rating).
-
De-rating: In high-temperature environments or when multiple breakers are mounted side-by-side without spacing, the rated current may need to be adjusted (de-rated).
-
Tightening Torque: Ensure terminals are tightened to the manufacturer’s specified torque to prevent overheating and arc faults.
-
Direction of Feed: Ensure the line and load sides are correctly wired according to the markings on the device for proper functionality.
