Allen Bradley 1492-SP1C130 Miniature Circuit Breaker

Product Overview

The Allen Bradley 1492-SP1C130 acts as a high-precision supplemental protector within the 1492-SP product line. This single-pole miniature circuit breaker provides essential overcurrent protection for sensitive control circuits, PLC I/O points, and small motor loads. We supply this component as 100% Brand New and Factory Original, ensuring that the factory-calibrated trip curves remain intact to safeguard your downstream automation assets.

Technical Specifications

The 1492-SP1C130 utilizes a compact thermal-magnetic architecture to manage AC voltage transients and sustained overloads:

Engineering Advantages

• Optimized C-Curve Response: The C-type magnetic trip characteristic handles moderate inductive inrush currents. This prevents nuisance tripping during the startup of small solenoids or control transformers while maintaining instantaneous protection against high-level short circuits.

• High-Density DIN Rail Integration: The slim 0.20 lb chassis minimizes the physical footprint on 35mm DIN rails. This allows engineers to increase the number of protected channels within standard control cabinets without expanding the enclosure size.

• Vibration-Resistant Terminals: The terminal design utilizes high-pressure clamping to secure wiring against industrial vibrations. This maintains a low-resistance path and prevents localized overheating, a common failure point in legacy control panels.

• Dual Trip Mechanism: This breaker combines a bimetallic element for time-delayed thermal protection with an electromagnetic coil for instantaneous magnetic tripping. This dual-action design ensures total circuit safety across both gradual overloads and sudden faults.

FAQs

• Is this 1492-SP1C130 unit genuinely new?

  Yes. We provide only 100% Brand New original Allen Bradley stock. Each unit arrives in its original factory packaging with all manufacturing stamps and safety certifications intact.

• What is the difference between a Supplemental Protector and a Branch Circuit Breaker?

  The 1492-SP series serves as a Supplemental Protector (UL 1077). You must install it downstream of a primary branch circuit protector (UL 489). It provides localized, fine-tuned protection for individual components inside the control panel.

• Can I replace a lower amperage 1492 breaker with this 13A model?

  Only if your conductor size and downstream load ratings support 13 Amps. Increasing the breaker rating without verifying the wire gauge (AWG) creates a fire hazard. Always consult your electrical schematics before upgrading amperage ratings.

• Does the "Discontinued" status affect the performance of new stock?

  Not at all. While the manufacturer may have moved to newer series, these Brand New units meet the original technical specifications. Sourcing original stock eliminates the need for expensive rewiring or panel modifications required by newer, differently-sized replacements.
