Product Description:
The model MCD3018-T5-B21-CV4 is a compact soft starter designed to ensure smooth motor startup and shutdown. It features timed voltage ramp up to gradually bring motors to full speed. This device is suitable for applications requiring up to 25 A motor load and is optimized to minimize electrical and mechanical stress.
This MCD3018-T5-B21-CV4 Soft Starter supports a maximum motor load of 25 A and provides fully adjustable acceleration and deceleration times that ranges from 0 to 10 seconds. It includes an adjustable initial torque level of up to 85 % that allows precise control during motor startup. A breakaway function (kick start) is also included for applications requiring higher starting torque. The model offers universal control voltage compatibility from 24 to 480 V AC or DC. The device is capable of automatic phase loss detection and adapts automatically to both 50 Hz and 60 Hz power supply frequencies. The LED status indicators provide clear operational status that enables quick diagnostics. The soft starter allows unlimited start/stop cycles per hour for 15 A and 25 A models. The built-in varistor protection guards internal circuits from voltage spikes. This model implements a timed voltage ramp up system. This feature ensures the motor voltage gradually increases to full line voltage based on user set time through a rotary switch.
The housing of the MCD3018-T5-B21-CV4 soft starter is made of self extinguishing PPO UL94V1 material that ensures fire resistance. The heatsink is constructed from black anodized aluminum for effective thermal dissipation while the base is made of electroplated steel. These materials ensure long term reliability under industrial conditions. The unit’s modular design allows flexible panel mounting and space saving installations in control cabinets.
Frequently Asked Questions about MCD3018-T5-B21-CV4:
Q: How does the 175G4001 Soft Starter enhance motor reliability during frequent start-stop cycles in demanding applications?
A: It delivers adjustable ramp-up and ramp-down times from 0 to 10 seconds, which reduces mechanical stress. This control helps extend motor lifespan and improves overall system reliability.
Q: What kind of voltage flexibility does the 175G4001 Soft Starter offer for control circuit integration across global installations?
A: It supports control voltages ranging from 24 to 230 V AC/DC for 230 V systems and up to 480 V AC/DC for 400–600 V systems. This wide compatibility simplifies implementation in varied electrical environments.
Q: How does the 175G4001 Soft Starter manage initial torque for high-friction or loaded motor starts?
A: The initial torque is adjustable from 0 to 85% of nominal torque. An optional kick start function enhances performance during heavy mechanical loads or static friction conditions.
Q: How does the 175G4001 Soft Starter handle electrical stress in industrial environments with transient surges?
A: It is rated for insulation up to 660 V AC and withstands impulse voltages up to 4 kV. Its design complies with installation category III, supporting resilience under high-energy transients.
Q: What kind of operational responsiveness can be expected from the 175G4001 Soft Starter during control signal changes?
A: The unit ensures a maximum response time of 70 milliseconds for input signal recognition. This enables quick actuation and coordination in real-time automation or protection systems.
