Product Description:

The 136G8763 refers to the MCD60063BT5S1X20CV2 product. This soft starter is part of the MCD 600 Soft Starter series. The 136G8763 is designed for high-reliability motor control and protection.

The Danfoss 136G8763 is designed to withstand harsh industrial environments. It has a rated nominal current of 63 A and can accommodate a wide mains voltage range of 200-525 V AC. It accepts control voltages of 110-120 V AC or 220-240 V AC, providing installation versatility. The major frequency range is 50-60 Hz. The gadget includes an internal bypass for increased energy efficiency, which can reach 99% while in operation. The dimensions are tiny, with a width of 152 mm, a height of 336 mm, and a depth of 231 mm. The weight is about 4.9 kg, making it easy to install in compact locations. Cooling clearance is greater than 100 mm at the top and bottom, and greater than 10 mm on the sides. The protection rating is IP20, making it suitable for conventional panel enclosures. It is certified for use up to 1000 m altitude, with derating required above that level. The inputs consist of two fixed and two programmable digital inputs that operate at 24 V DC and 8 mA each. The analog output can handle a maximum load of 600 Ω with an accuracy of ±5%. The relay outputs comprise a main contactor (usually open), changeover relay output A, and normally open relay output B, all with a capacity of up to 10 A at 250 V AC. Short-circuit protection satisfies Type 1 and Type 2 coordination. The unit has internal bypass contacts with a rated life of 100,000 operations.

The Danfoss 136G8763 is CE, UL and marine certified. Installation supports both in-line and inside delta configurations. Humidity tolerance is 5–95% RH. The unit can operate in temperatures ranging from -10°C to +60°C, with derating over 40°C. Vibration is compliant to IEC 60068-2-6.

Frequently Asked Questions about 136G8763:

Q: How does the internal bypass feature of product code 136G8763 improve efficiency?

A: The internal bypass reduces heat generation and power loss during normal running. This leads to higher energy efficiency and lower operational costs.

Q: How does the USB setup port benefit the user of product code 136G8763?

A: The USB port enables easy upload and download of configuration settings. This streamlines commissioning and parameter backup.

Q: Why is the vibration compliance to IEC 60068-2-6 important in the MCD60063BT5S1X20CV2?

A: This ensures reliable performance in environments with mechanical vibrations. It helps protect sensitive electronics from long-term mechanical stress.

Q: How does motor thermistor input enhance motor protection in product code 136G8763?

A: The thermistor input trips the soft starter if the motor overheats. This prevents potential motor damage from excessive temperature.

Q: Why is a pollution degree rating of 3 significant for the MCD 600 Soft Starter Series?

A: It indicates suitability for industrial environments with conductive dust. This ensures safe operation in demanding locations.
