Eaton PXCE-B

Eaton PXCE-B is a modular low-voltage distribution circuit breaker, specially designed for residential premises, small commercial buildings, and industrial switchgear cabinets. Featuring a compact plastic enclosure and visual operation buttons, it delivers fast, reliable circuit protection and manual control functions.

Key Technical Specifications

• Rated Current: Multiple options available, including 6 A, 10 A, 16 A, 20 A, 25 A, and 32 A.
• Rated Voltage: Ue = 230 V (single-phase) / 400 V (three-phase), compliant with the IEC 60947-2 standard.
• Trip Characteristics: Selectable B, C, D curve types to meet diverse starting current requirements.
• Pole Count: Configurable with single-pole, double-pole, three-pole, and four-pole modules for flexible combinations.
• Short-Circuit Breaking Capacity: IC ≥ 6 kA, satisfying the short-circuit protection needs of conventional power distribution systems.
• Wiring Method: Screw-type or spring-type terminals for convenient on-site quick wiring.
• Dimensions: 18 mm in width and 70 mm in depth (per single module), suitable for side-by-side mounting on standard DIN-Rail to save installation space.

Product Features

1. Modular DesignEach circuit breaker functions as an independent module, allowing flexible addition or removal based on power distribution demands. This design facilitates easy later-stage capacity expansion or system modification.
2. User-Friendly OperationEquipped with yellow manual operation buttons on the front panel, it supports manual closing, opening, and testing functions, enabling quick and intuitive on-site commissioning.
3. High ReliabilityThe impact-resistant plastic enclosure and high-quality contact materials ensure stable electrical performance during long-term operation.
4. International Standard ComplianceIt meets safety and performance specifications such as IEC 60947-2 and EN 60947-1, making it suitable for global market applications.
5. Low Maintenance CostThe modular structure allows replacement of a single circuit breaker without disassembling the entire switchgear cabinet, significantly reducing maintenance downtime.

Structure and Components

• Enclosure: High-strength white plastic enclosure providing dustproof and moisture-proof protection.
• Operation Buttons: Yellow round buttons for manual closing/opening and function testing.
• Terminal Block: Screw-type or spring-type terminals on both sides, corresponding to input, output, and auxiliary wiring respectively.
• Trip Mechanism: Built-in mechanical trip mechanism that achieves overload protection based on the selected B/C/D curve.
• Indicator Light: A status indicator shows the on/off state of the circuit breaker, facilitating quick on-site status identification.

Typical Application Areas

• Residential Power Distribution: Overload protection for branch circuits such as kitchens, living rooms, and air conditioners.
• Small Commercial Buildings: Switchgear cabinets in offices, retail stores, and catering establishments.
• Industrial Switchgear Cabinets: Protection for low-power motors, lighting circuits, and control systems.
• Data Centers/Computer Rooms: Used for quick isolation and maintenance of low-voltage power distribution branches.

Installation and Maintenance Guidelines

Installation

1. Insert the module into the standard DIN-Rail and ensure the buckle is securely fastened.
2. Wire the device according to the electrical drawings: connect the neutral/ground wire first, then the phase wire to avoid incorrect wiring.
3. Verify that the operation buttons and indicator lights are functioning properly.

Commissioning

1. Perform closing/opening tests via the manual buttons to confirm smooth mechanical operation.
2. Use dedicated testing equipment to check if the trip characteristics conform to the selected B/C/D curve.

Daily Maintenance

1. Regularly inspect the tightness of terminals to prevent poor contact caused by loosening.
2. Remove dust and corrosive substances from the enclosure surface to maintain good heat dissipation.
3. In case of abnormal tripping, first check if the load exceeds the rated current, then consider replacing the corresponding module.
