Ultra-low Loss & High Efficiency: SCB13 series has 20% lower no-load loss than SCB11, meeting the latest energy efficiency standards, significantly reducing long-term operating costs.

 

Fire & Explosion Proof, Eco-friendly: Epoxy resin casting, flame-retardant and self-extinguishing, no oil leakage, no harmful gas release, safe for indoor, high-rise, and public areas.

 

Low Partial Discharge & Noise: Vacuum-pressure casting, partial discharge ≤5 pC; optimized core lamination and structural design, noise 10–15 dB lower than conventional standards.

 

Excellent Moisture Resistance: Can operate in high humidity environments; no pre-drying needed after shutdown, ready to start.

 

Intelligent Temperature Protection: Equipped with multi-point temperature monitoring, automatic fan start/stop, over-temperature alarm and trip functions, ensuring reliable operation.

 

Robust Mechanical Strength: Cast coil structure resists short-circuit electrodynamic force, suitable for harsh grid conditions.

 

 

• Built-in PT100 probes in 3 phase windings to detect the real-time temperature of windings and cycle display them in the digital screen.
• Open circuit alarm and fault self-check alarm display and signal output.
• 3 stages automatically actions while the temperature reached to the set value, 1st stage the cooling fans start automatically, 2nd stage high temperature alarm,3rd stage over temperature trip.
• Fans manual/auto control switch, timing start/stop, history data output.
• 4-20mA current output
• RS485 Modbus communication protocol
• Environment temperature measurement
• Core temperature measurement
