The Siemens 3VL9300-4WF30 is an undervoltage release designed for use with 3VL series molded case circuit breakers (MCCBs). This device provides protection against undervoltage conditions by automatically tripping the circuit breaker when the voltage drops below a predetermined level. This prevents damage to connected equipment and ensures safe operation of electrical systems.

Applications:

• Industrial automation systems
• Motor control centers
• Power distribution boards
• Critical power systems
• Applications requiring undervoltage protection

Features:

• Undervoltage protection for MCCBs
• Automatic tripping of the circuit breaker upon undervoltage detection
• Adjustable undervoltage release setting
• Compatible with Siemens 3VL series MCCBs
• Remote reset capability (optional)
• Compact design for easy integration

Benefits:

• Protects connected equipment from damage due to undervoltage conditions
• Ensures safe operation of electrical systems
• Reduces downtime and maintenance costs
• Improves system reliability
• Easy to install and configure

Additional Details:

The 3VL9300-4WF30 undervoltage release is designed to be installed within the 3VL series MCCB. It monitors the voltage level and, when the voltage drops below the set threshold, triggers the circuit breaker to trip, disconnecting the power supply. The undervoltage release setting is typically adjustable to allow for customization based on the specific application requirements. Some models may also offer remote reset capability, allowing the circuit breaker to be reset remotely after an undervoltage event. The undervoltage release is an essential component for protecting sensitive equipment and ensuring the safe operation of electrical systems in various industrial and commercial applications.
