Summary

Forklifts' electrical systems need protection from electrical faults, short circuits, and overloads that can damage their components and cause accidents. For this purpose, forklifts have circuit breakers, interrupting the current flow when it exceeds a certain level. 

In this article, we will explain the need and functionalities of forklift circuit breakers, the types of circuit breakers used in forklifts, the wiring diagram of forklift circuit breakers, the factors to consider when buying circuit breakers, the replacement guide, and why you should choose Pallet Jackson to buy forklift circuit breakers.

Forklift Circuit Breaker - Need and Functionalities 

A forklift circuit breaker is a device that protects the electrical equipment and wiring in a forklift from overcurrent, short circuit, or overload. A circuit breaker detects when the current exceeds a predetermined level and interrupts the flow of electricity, preventing damage or fire. A circuit breaker can be reset manually or automatically after clearing the fault.

A forklift circuit breaker has several functions, such as:

• Protects battery, motor, controller, lights, horn, and other electrical components in a forklift.
• Disconnect or isolates the electrical power from the forklift when needed.
• Protect the electrical system from shortcircuits, voltage faults, or malfunctions.
• Provide a visual indication of the status of the circuit (on, off, tripped)

Types of Circuit Breakers Used in Forklifts

Different circuit breakers are used in forklifts, depending on the voltage, current, and application. Some of the common types are:

1. Thermal Circuit Breakers

These are the most basic circuit breakers that use a bimetallic strip or a thermistor to sense the temperature rise in the circuit. When the temperature exceeds a certain threshold, the strip bends or expands and breaks the contact, interrupting the current flow. Thermal circuit breakers are slow to react and have low accuracy, but they are cheap and easy to install. They are suitable for low-voltage and low-current applications such as lighting circuits.

2. Magnetic Circuit Breakers

These are more advanced circuit breakers that use an electromagnet to sense the current flow in the circuit. When the current exceeds a certain level, the electromagnet attracts a metal armature that breaks the contact, interrupting the current flow. Magnetic circuit breakers are fast to react and have high accuracy, but they are more expensive and complex than thermal circuit breakers. They are suitable for high-voltage and high-current applications such as motor circuits.

3. Thermal-magnetic Circuit Breakers

These hybrid circuit breakers combine thermal and magnetic elements to provide dual protection against the circuit's temperature rise and current surge. They have two contacts: one that breaks due to thermal expansion and one due to magnetic attraction. Thermal-magnetic circuit breakers are versatile and reliable but are more costly and bulky than thermal or magnetic circuit breakers. They are suitable for medium-voltage and medium-current applications such as battery circuits.

4. Electronic Circuit Breakers

These are modern circuit breakers that use electronic sensors and microprocessors to monitor and control the current flow in the circuit. They can be programmed to adjust their sensitivity and response time according to different conditions and requirements. Electronic circuit breakers are smart and precise but are also very expensive and require an external power supply and communication interface. They are suitable for sophisticated applications such as computerized controls.

Forklift Circuit Breaker Wiring Diagram 

A forklift circuit breaker wiring diagram is a schematic representation of how the circuit breakers are connected to the electrical system of a forklift. It shows the location, type, rating, and function of each circuit breaker and the wires, terminals, connectors, switches, fuses, relays, and other components involved in the circuit.

Moreover, the wiring diagram of a forklift circuit breaker is essential to understand the electrical system of the forklift. It shows how the components of the electrical system are connected and how they work together. 

Check out the following PDF to understand the wiring diagram of circuit breakers used in forklifts:

The wiring diagram may vary depending on the type, model, and configuration of your forklift and its components. You should always refer to the wiring diagram your forklift manufacturer or dealer provided before attempting to install, replace, or modify your forklift circuit breaker.

Factors to Consider When Buying Circuit Breakers

When buying circuit breakers, there are several factors to consider. Here are some of the most important factors to keep in mind:

Current Rating

This is the maximum amount of current that the circuit breaker can carry continuously without tripping. It should match the current requirements of the forklift and its components. The current rating is usually expressed in amps (A) or milliamps (mA).

Voltage Rating

This is the maximum voltage that the circuit breaker can withstand without breaking down. It should match the battery's voltage or the forklift's power source. Voltage ratings are usually expressed in volts (V) or kilovolts (kV).

Trip Characteristics

Circuit breakers have different trip characteristics, such as instantaneously or with a time delay. Consider the nature of the loads and your forklift's specific requirements when selecting the circuit breaker's trip characteristics. For example, a circuit breaker with time delay trip characteristics may be suitable if your forklift has high starting currents or frequent motor startups.

Interrupting Capacity

The interrupting capacity or short-circuit current rating indicates the maximum fault current the circuit breaker can safely interrupt. Ensure that the circuit breaker you choose has an interrupting capacity that exceeds the available fault current in your forklift system. This is crucial for safety and preventing equipment damage during fault conditions.

Size and Mounting

Consider the physical size and mounting options of the circuit breaker. Ensure that it fits within the available space in your forklift's electrical panel or enclosure. Also, check if it has the appropriate mounting features, such as DIN rail or panel mounting, for easy installation.

Replacement Guide

To replace a faulty or damaged circuit breaker in your forklift, you should follow these steps:

• Disconnect the battery from your forklift to avoid electric shock or fire
• Locate the circuit breaker that needs to be replaced by referring to your forklift's wiring diagram
• Remove any covers or panels that may obstruct access to the circuit breaker
• Disconnect any wires or connectors that are attached to the circuit breaker
• Unscrew or unclip any mounting hardware that secures the circuit breaker to its base or frame
• Pull out or slide out the old circuit breaker from its position
• Insert or slide the new circuit breaker into its position
• Screw or clip any mounting hardware that secures the new circuit breaker to its base or frame
• Connect any wires or connectors that are attached to the new circuit breaker
• Replace any covers or panels that were removed earlier
• Reconnect the battery to your forklift and test if the new circuit breaker works properly
