Siemens 3VA Series MCCB, 125A Current Rating, 690V Rated AC Voltage - 3VA1112-3ED36-0AA0

This moulded case circuit breaker (MCCB) from Siemens is designed to provide outstanding protection and reliability in industrial applications. The 3-pole configuration supports a current rating of 125A, along with an impressive breaking capacity of 25 kA at a maximum voltage rating of 690V. With a fixed mounting style, it ensures stability and durability in any environment.

Features & Benefits

• Thermal-magnetic circuit breaker combines overload and short-circuit protection

• High breaking capacity ensures effective protection against faults

• Designed for three-pole configurations for versatile system integration

• Capable of operating at 690V AC and 500V DC to meet diverse voltage needs

• Quick reset using a toggle switch for user-friendly operation

• Compact design allows easy installation in various industrial settings

Applications

• Used for line protection in electrical panels

• Suitable for industrial automation control systems

• Ideal for protecting motors and machinery from overloads

• Implemented in power distribution systems requiring high reliability

• Utilised in environments with high fault current scenarios

How does this MCCB manage overheating during continuous operation?

The thermal-magnetic mechanism responds to heat generated by excess current, allowing the device to trip and disconnect the circuit, preventing potential damage due to overheating.

What is the operational current range at different temperatures?

At 40°C, the operational current remains at 125A, while at higher temperatures, it gradually decreases to 114A at 70°C, ensuring performance stability under varying thermal conditions.

Can this circuit breaker be retrofitted for specific applications?

While primarily designed for fixed installation, it includes features for neutral conductors and is adaptable for various electrical configurations, though specific retrofitting options may depend on installation conditions.
