CB125A 1P,125A,DC110V Limit sensor

CB125A 1P,125A,DC110V Limit sensor
Key Specifications

• Type: 1-Pole (1P) Circuit Breaker
• Rated Current: \(125 \text{ A}\)
• Rated Voltage: \(110 \text{ V DC}\) (often supports \(60 \text{ V DC}\))
• Breaking Capacity: \(10\text{ kA}\) (handles both overload and short-circuit faults) 

Typical Use Cases

• Industrial Automation & Sensors: Used as a protective intermediary for high-amperage limit switches and sensors in heavy-duty conveyors, automotive lifts, and linear actuators.
• Telecommunications: Serves as a primary DC disconnect and overcurrent protector in cell towers.
• Solar & EV Applications: Frequently deployed in battery banks and electric vehicle charging setups. 

Important Notes for Installation

• Polarity: Ensure correct line (positive/negative) orientation if the specific breaker is polarity-sensitive, though many modern models offer non-polarity wiring.
• Accessories: Standard units (like those from Chint) allow the attachment of auxiliary contacts and shunt release modules.
• Safety: When designing limit-sensing circuits, size the wire gauge appropriately for \(125 \text{ A}\) loads to prevent thermal melting.
