SUNTREE AC Protection Devices are designed to protect electrical systems and equipment against overcurrent, short circuits, and voltage surges. This category includes Miniature Circuit Breakers (MCBs), Moulded Case Circuit Breakers (MCCBs), and AC Surge Protection Devices (SPDs) for residential, commercial, industrial, and solar power systems.
The right product depends on the type of electrical fault you need to protect against, the system current, and the application.
| Product | Type | Main Protection | Typical Application | Current / Rating |
|---|---|---|---|---|
| SUNTREE SCB8-63 | AC MCB | Overcurrent & short circuit | Residential and small electrical circuits | 6A–63A, up to 6kA |
| SUNTREE SUP1H | AC SPD | Voltage surge | Electrical panels, solar & sensitive equipment | Imax up to 65kA |
| SUNTREE SM8 | AC MCCB | Overcurrent & short circuit | Industrial and high-current systems | High-current applications |
| Device | What It Protects Against | How It Works | Where It Is Used |
| SCB8-63 MCB | Overload and short circuit | Automatically disconnects the circuit when excessive current is detected | Homes, offices, distribution boards, small solar systems |
| SUP1H AC SPD | Voltage surges and transient overvoltage | Diverts dangerous surge energy away from connected equipment | AC panels, solar systems, commercial buildings, sensitive electronics |
| SM8 MCCB | Overcurrent and short circuit | Interrupts high fault currents and protects larger circuits | Industrial systems, main distribution boards, large electrical installations |
Choose the SUNTREE SCB8-63 MCB when you need protection for individual circuits and smaller electrical loads. It is suitable for residential and commercial distribution boards and provides protection against overload and short circuits.
Choose the SUNTREE SUP1H AC Surge Protector when your main concern is voltage surges caused by lightning, switching operations, or disturbances in the electrical network. It is particularly useful for protecting sensitive electrical and electronic equipment.
Choose the SUNTREE SM8 MCCB for higher-current and industrial applications where a conventional MCB is not sufficient. MCCBs are commonly installed as main breakers or for protecting larger distribution circuits.
SUNTREE AC protection products can be used in:
For complete protection, different devices can be used together. For example, an MCB or MCCB can provide overcurrent protection, while an AC SPD provides surge protection. The correct combination depends on the electrical system and installation requirements.
AC protection devices are electrical components designed to protect AC circuits and equipment against faults such as overcurrent, short circuits, overloads, and voltage surges.
An MCB is generally used for smaller electrical circuits, while an MCCB is designed for higher-current applications and larger electrical distribution systems.
An AC Surge Protection Device (SPD) protects electrical equipment from short-duration voltage surges by diverting excessive transient energy away from the protected circuit.
Yes. They provide different types of protection and can be combined in an electrical distribution system when properly selected and installed.
It depends on the part of the system being protected. The SCB8-63 and SM8 can provide AC overcurrent and short-circuit protection, while the SUP1H is designed for AC surge protection. The correct model should be selected according to the system voltage, current, and installation design.
