CHINT DZ47-60 C25 25A Single-Pole Circuit Breaker – 6kA

The CHINT DZ47-60 C25 miniature circuit breaker is a single-pole electrical protection device designed for compatible electrical control systems and equipment. Rated at 25 amps with a Type C trip characteristic, it provides overload and short-circuit protection for appropriately designed circuits.

This compact breaker features a manual ON/OFF operating lever, screw terminal connections, and a DIN-rail mounting design. Its narrow, single-pole housing makes it suitable for installation in compatible electrical distribution and control enclosures.

The photographed breaker is manufactured by CHINT and carries a 230/400V AC voltage marking and a 6,000A short-circuit breaking capacity.

Whether replacing a damaged breaker or maintaining compatible laser equipment, the DZ47-60 C25 provides electrical protection when correctly selected and installed.

Important: This is a single-pole circuit breaker. It must not be substituted for a two-pole breaker or a residual-current protection device without verifying the equipment's electrical requirements.

Key Features

• 25A Rated Current: Designed for compatible circuits requiring a 25-amp protective device.
• Single-Pole Design: Provides overcurrent protection and switching for one circuit pole.
• Type C Trip Characteristic: Accommodates brief startup current in appropriately designed electrical circuits.
• Overload Protection: Trips when excessive current persists beyond the breaker's operating limits.
• Short-Circuit Protection: Responds to qualifying short-circuit faults to interrupt electrical current.
• 6kA Breaking Capacity: Marked for a 6,000-amp short-circuit interrupting capacity under specified conditions.
• Manual ON/OFF Lever: Allows manual switching and resetting after a fault has been corrected.
• DIN-Rail Mounting: Designed for mounting on compatible 35mm DIN rails.
• Screw Terminal Connections: Provides connection points at the top and bottom of the breaker.
• Compact Housing: Narrow construction for compatible electrical cabinets and control panels.

Understanding the C25 Rating

The C25 designation identifies two electrical characteristics of the circuit breaker.

25A Rated Current: The number 25 identifies the breaker's rated current of 25 amps. The breaker must be appropriately sized for the wiring, electrical load, and equipment requirements.

Type C Trip Curve: The letter C identifies its instantaneous magnetic trip characteristic. Type C breakers generally trip magnetically at approximately five to ten times their rated current.

This allows the breaker to tolerate certain brief startup currents from compatible electrical equipment while still providing overload and short-circuit protection.

Important: The Type C trip characteristic does not allow a circuit to operate continuously above its 25A rating.

Single-Pole Circuit Protection

The photographed DZ47-60 C25 is a single-pole miniature circuit breaker. Unlike a two-pole model, it contains one protected switching pole with one operating handle.

When an overload or qualifying short circuit occurs, the breaker trips and interrupts the conductor connected through its protected pole.

This configuration is intended for appropriately designed electrical circuits that require single-pole protection.

Note: This breaker provides overcurrent protection only. It does not provide dedicated electrical-leakage or ground-fault protection like a residual-current circuit breaker (RCCB) or an RCBO.

Understanding the 6kA Breaking Capacity

The 6,000A marking identifies the breaker's rated short-circuit breaking capacity under specified test conditions.

Breaking capacity refers to the maximum prospective short-circuit current a breaker is designed to interrupt safely under its rated conditions. It is different from the breaker's normal operating current.

A 25A breaker with a 6kA breaking capacity is not designed to carry 6,000 amps during normal operation.

The available fault current at the installation must be within the breaker's approved interrupting capability. Always confirm the required electrical ratings before replacing an existing breaker.

Compatibility

This circuit breaker is intended for compatible electrical systems requiring a 25A, Type C, single-pole miniature circuit breaker with the appropriate voltage, frequency, and breaking capacity.

Before ordering, compare the replacement breaker with your original component:

• Manufacturer and model designation
• 25A rated current
• Type C trip characteristic
• Single-pole configuration
• Rated operating voltage and frequency
• 6kA short-circuit breaking capacity
• Terminal arrangement and wiring requirements
• Physical dimensions and available mounting space
• DIN-rail compatibility
• Applicable electrical standards and equipment requirements

Important: The photographed unit is marked 50Hz. Compatibility with 60Hz electrical systems has not been established from the supplied product information. Verify the manufacturer's rating and suitability before installation.

The DZ47-60 model family includes breakers with different current ratings, pole configurations, and electrical characteristics. Do not assume that breakers with similar housings are interchangeable.

Do not install a breaker with a higher amperage rating, insufficient breaking capacity, or different number of poles as a substitute for the original protective device.

Installation & Safety

• Installation and replacement should be performed by a qualified electrician familiar with the equipment.
• Disconnect and isolate the electrical supply before opening the machine's electrical cabinet.
• Verify that the affected circuits are de-energized using appropriate test equipment.
• Confirm that the replacement breaker's current rating, voltage, frequency, trip curve, breaking capacity, and pole configuration match the application.
• Install the breaker onto a compatible DIN rail according to the manufacturer's instructions.
• Connect conductors according to the terminal markings, circuit diagram, and equipment requirements.
• Use correctly sized conductors and the manufacturer's specified terminal tightening torque.
• Inspect all connections and surrounding electrical components before restoring power.
• Complete the required electrical safety and functional checks before returning the machine to service.

Safety Note: If the replacement breaker trips repeatedly, do not continue resetting it. Repeated trips may indicate an overload, short circuit, damaged wiring, failed electrical component, or another condition requiring diagnosis.

Never bypass, modify, or oversize a circuit breaker to prevent it from tripping. Correct electrical protection is essential to equipment safety.
